Mounting and installation
3.1
Regulations
•
•
•
•
Prior to installing the units, power must be turned off
The connections for mains and low-voltage are separated
For wiring, the requirements of safety class II must be satisfied.
One and the same sensor cannot be connected to several inputs
Sensor and power cables must not be run in the same cable duct
3.2
Heat pump controller RVS..
Planning
• Air circulation around the controller must be ensured, allowing the unit to emit the
heat produced by it.
A clearance of at least 10 mm must be provided for the unit's cooling slots at the top
and bottom of the housing.
That space should not be accessible and no objects should be placed there. If the
controller is enclosed in another (insulating) casing, a clearance of up to 100 mm
must be observed around the cooling slots
• The controller is designed conforming to the directives for safety class II devices
mounted in compliance with these regulations
• Power to the controller may only be supplied when completely fitted. If this is not
observed, there is a risk of electric shock hazard near the terminals and through the
cooling slots
• The controller must not be exposed to dripping water.
• Permissible ambient temperature when mounted and when ready to
operate: 0…50 °C
• Power cables must be clearly separated from low-voltage cables (sensors) observing
a distance of at least 100 mm
Mounting location
• Heat pump
• Control panel
• Housing for wall mounting

Heating curve slope
Heating curve displacement
Heating curve adaption
The heating curve generates the flow temperature setpoint, which is used to maintain a
certain flow temperature depending on the prevailing weather conditions. The heating
curve can be adjusted via a number of settings, thus matching heat output and room
temperature to individual needs.
Heating curve slope
The steeper the heating curve slope, the greater the change of flow temperature at low
outside temperatures. In other words, if the room temperature is not correct at low
outside temperatures, but at higher outside temperatures, the heating curve slope
needs readjusting.
Increasing the setting:
Raises the flow temperature, especially when outside
temperatures are low.
Lowers the flow temperature, especially when outside
temperatures are low.
Decreasing the setting:
The set heating curve is based on a room temperature setpoint of 20 °C. If the room
temperature setpoint is adjusted, the heating curve adapts automatically to the new
value.

displacement
Parallel displacement of the heating curve is used to change the flow temperature
evenly across the entire outside temperature range or, in other words, if the room
temperature is always too high or too low, a readjustment must be made via parallel
displacement.
Adaption
Adaption of the heating curve is used by the controller to automatically adapt the
heating curve to the prevailing weather conditions. It can only be switched on or off. In
that case, a readjustment of heating curve slope and parallel displacement is not
required.

* Outside sensor required
Pure weather
compensation
The flow temperature is calculated via the heating curve, depending on the composite
outside temperature.
This type of compensation calls for a correct adjustment of the heating curve since in
that case the control gives no consideration to the room temperature.
Weather compensation
with room influence
The deviation of the actual room temperature from the setpoint is measured and taken
into account when controlling the temperature. Heat gains can thus be considered,
ensuring more accurate room temperature control. The authority of deviation is set as a
percentage figure. The better the reference room (correct room temperature, correct
mounting location, etc.) the higher the value can be set.
• Example:
Approx. 60%
Approx. 20%
Good reference room conditions
Unfavorable reference room
To activate the function, following must be considered:
• A room sensor must be connected
• The ”Room influence“ setting must be between 1 and 99
• There should be no thermostatic radiator valves in the reference room (mounting
location of room sensor) (If such valves are present, they must be set to their fully
open position)
Pure room compensation
The flow temperature is controlled depending on the room temperature setpoint, the
current room temperature and the progression of the room temperature. For example, a
slight increase of the room temperature causes an immediate drop of the flow
temperature.
To activate the function, following must be considered:
• A room sensor must be connected
• “Room influence“ must be set to 100%
• There should be no thermostatic radiator valves in the reference room (mounting
location of the room sensor). (If such valves are present, they must be set to their
fully open position)

Overtemp prot pump heating circuit
In the case of heating plants with pump heating circuits, the flow temperature of the
heating circuit can be higher than the flow temperature called for by the heating curve,
the reason being higher requests from other heat consumers (mixing heating circuit,
DHW charging, external heat demand), or a parameterized minimum heat source
temperature. As a result of this too high flow temperature, the pump heating circuit
would assume excessive temperatures.
Function "Overtemperature protection for pump circuits" ensures that the energy supply
for pump heating circuits corresponds to the demand from the heating curve by
activating / deactivating the pump.

signal, the valve opens. When there is no signal, the valve closes automatically.
3-position
The controller drives the actuator with 2 relay outputs. One of the outputs is used for
opening the valve, the other for closing the valve.

For the 2-position actuator, the "2-position switching differential" must also be adapted.
The switching differential has no impact on 3-position actuators.
Actuator running time
For the 3-position actuator, the running time of the mixing valve actuator can be
adjusted. The actuator running time has no impact on 2-position actuators.
Floor curing function
The floor curing function serves for controlled drying of the floor. It controls the flow
temperature according to a certain temperature profile. Drying of the floor is ensured
via the floor heating system by the mixing or pump heating circuit.
• Observe the relevant standards and regulations of the company supplying the floor!
• Proper functioning is ensured only when the plant is correctly installed (hydraulic
system, electrical installation, settings)!
If not observed, the floor might get damaged!
• The function can be aborted prematurely by selecting Off
• Maximum limitation of the flow temperature remains active

The temperature change always takes place at midnight. The start day (day 0), that is,
the period of time from activation to midnight does not count as a functional day.
The setpoint used for the start day is the value of the first functional day.
During "Floor curing mode", the profile temperature is limited within the 2 limit values
“Flow temperature setpoint maximum“ (TVMax) and “Flow temperature setpoint
minimum“ (TVmin).
The function is terminated when the functional days have elapsed or when it is
deactivated with the parameter.
There is only one profile which applies to all 3 heating circuits.
Start in the summer
In the case of heat pumps controlled according to the return temperature, the switch-on
point for the heat pump may not be reached in the summer.
For this reason, the return temperature needed for switching on the heat pump is
calculated based on the flow temperature setpoint minus the required temperature
differential (parameter 5801). If the temperature acquired by the return temperature
sensor lies above that temperature, the heat pump is not put into operation and,
therefore, the floor curing function started too late (only when the temperature increase
resulting from the floor curing function requires the heat pump to be switched on).
Manually
In manual operating mode, no temperature profile is completed. The required flow
temperature is set individually for every heating circuit, using parameter “Floor curing
setp manually”.

During the time the floor curing function is performed, the heating circuit flow
temperature is compared with the flow temperature setpoint according to the profile or
the manually selected flow temperature setpoint.
In the case of mixing heating circuits, the flow temperature sensor is monitored. With
pump heating circuits, the common flow temperature is used in place of the flow
temperature.
The temperature is regarded maintained if the deviation from the setpoint is less than 2
K. The period of time during which the flow temperature is correct is added up by a
meter.
If the required temperature is not reached after more than 1 hour, the meter is stopped
until the deviation is smaller again than 2 K.
If the floor curing process is terminated, the days completed are saved and retained

When using a 2- or 4-pipe system with heat pump and process reversing valve, the
controller acquires the current room temperature and compares it with the room
temperature setpoint in order to calculate the required flow temperature setpoint. If the
buffer storage tank temperature is sufficiently low, the cooling circuit draws the required
cooling energy from that buffer. If the temperature is not low enough, or if there is no

begins when there is no heating request from heating circuit 1. Heating requests from
heating circuit 2 or heating circuit P are not taken into consideration.
The locking time is aborted by switching the operating mode button off and on again.

In summer, the cooling Comfort setpoint (902) is shifted upwards as the outside
temperature increases. This saves cooling energy, and prevents too great a differential
between the room and the outside temperature.
The resulting room temperature setpoint (cooling) can be displayed on the info level.
Summer comp start at OT
Summer compensation starts to take effect at the outside temperature set here. If the
outside temperature continues to rise, the Comfort setpoint is raised continuously.

Weather compensation
with room influence
The deviation of the actual room temperature from the setpoint is measured and taken
into account when controlling the temperature. In this way, account is taken of room
temperature deviations to facilitate more accurate room temperature control. The
authority of deviation is set as a percentage figure. The better the reference room
conditions (correct room temperature, correct mounting location, etc.) the higher the
value can be set.
• Example:
Approx. 60%
Approx. 20%
Good reference room conditions
Unfavorable reference room
To activate the function, following must be considered:
• A room sensor must be connected
• The ”Room influence“ setting must be between 1 and 99
• There should be no controlled valves in the reference room (mounting location of
the room sensor) (If such valves are installed, they must be set to their fully open
position)
Pure room compensation
The flow temperature is controlled depending on the room temperature setpoint, the
current room temperature and the progression of the room temperature. For example, a
slight increase of the room temperature causes an immediate drop of the flow
temperature.
To activate the function, following must be considered:
• A room sensor must be connected
• “Room influence“ must be set to 100%
• There should be no controlled valves in the reference room (mounting location of
the room sensor) (If such valves are installed, they must be set to their fully open

Room temperature limitation
The “Room temperature limitation” function makes it possible to deactivate the cooling

The heating circuit pump will be activated again as soon as the room temperature
returns to a level below the current room temperature setpoint.
During the time the “Room temperature limitation“ function is active, no cooling request
is sent to the source.

Mixing valve decrease
The refrigeration request from the mixing valve circuit to the source is reduced by the
preset value. The purpose of this reduction is to enable the mixing valve controller to
compensate for the variation in temperature caused by the source (2-position control).
Actuator type
2-position
The controller drives the actuator with only one relay output. When the output delivers a
signal, the valve opens. When there is no signal, the valve closes automatically.
3-position
The controller drives the actuator with 2 relay outputs. One of the outputs is used for
opening the valve, the other for closing the valve.
Switching differential 2pos
For the 2-position actuator, the "2-position switching differential" must also be adapted.
The switching differential has no impact on 3-position actuators.

For the 3-position actuator, the running time of the mixing valve actuator can be
adjusted. The actuator running time has no impact on 2-position actuators.

Flow temp setp incr hygro
To prevent condensation due to high levels of air humidity in the room, a hygrostat can
be used to ensure a fixed flow temperature increase. As soon as the air humidity
exceeds the value set on the hygrostat, the contact closes and the flow temperature
setpoint is increased by the amount set here.
The hygrostat must be assigned to one of the Hx inputs as "Flow setp increase hygro".
Flow setp incr start at r.h.
To prevent the formation of condensation due to excess indoor air humidity, a DC
0…10 V humidity measurement can be used to implement a continuous increase in the
flow temperature.
If the relative humidity in the room exceeds the value defined by "Flow setp incr start at
r.h." the flow temperature setpoint is increased continuously. The start of increase (949)
and the maximum increase (947) can be set.

Absolute priority
The mixing and pump heating circuits are locked until the DHW has reached the
required temperature level.

If the capacity of the heat source is no longer sufficient, the mixing and pump
heating circuits are restricted until the DHW has reached the required temperature
level.
No priority
DHW charging and space heating take place at the same time.
In the case of tightly sized heat sources and mixing heating circuits, the DHW
setpoint might not be reached if space heating calls for considerable amounts of
heat.

If there is a buffer storage tank, it must be stated whether the Hx circuit can draw heat
from it.
When making use of alternative heat sources, the buffer storage tank temperature is
used as a control criterion for the release of additional heat sources.
No
Hydraulically speaking, the consumer group is connected upstream of the buffer
storage tank and cannot draw any heating or cooling energy from it. The heat or
refrigeration request is forwarded to the heat / refrigeration source upstream of the
buffer storage tank.
Yes
The consumer group is connected downstream from the buffer storage tank. It draws
heating or cooling energy from the buffer storage tank and its temperature request is
taken into account by buffer management.
With primary controller /

The setting defines whether the primary controller / system pump has an impact on the
consumer group.
No
Hydraulically speaking, the consumer group is connected upstream of the primary
controller / system pump and cannot draw any “precontrolled” heating or cooling
energy. The heat or refrigeration request is always forwarded to the heat / refrigeration
source upstream of the primary controller.
Yes
The consumer group is connected downstream from the primary controller / system

No
Swimming pool heating through solar charging does not give consideration to any

Yes
Swimming pool heating through solar charging is given priority. This also applies if
storage tank charging priority (3822) would have to give preference to other heat
exchangers.
If none of the Hx inputs is used to release the swimming pool, the swimming pool
priority is determined by the parameter setting. For solar heating, the swimming pool is
always released.
If the swimming pool is enabled via one of the Hx inputs, swimming pool priority is
equivalent to the parameter setting. For solar heating, release at input Hx is now
required.
If 2 Hx inputs are used to enable the swimming pool, the swimming pool is given priority
when both Hx inputs are enabled. If only one of the Hx inputs is enabled, the swimming
pool priority is determined by the parameter setting. If none of the Hx inputs is enabled,
solar heating of the swimming pool is disabled.

The condenser pump can also be activated by the following functions:
Frost protection for the plant
Frost protection for the heat pump
Storage tank recooling
Passive cooling
Prerun time condenser
pump
Prior to starting the compressor, the condenser pump must be activated, enabling the
sensors to acquire the correct temperature.
Overrun time cond
pump
When the compressor is switched off, the condenser pump continues to run for the set
overrun time.
In the event of a heat pump fault, the condenser pump is deactivated until the fault is
corrected.
However, if activated, frost protection for the plant, the heat pump or the electric
immersion heater K25/K26 can still put the condenser pump into operation.

This function prevents the heat pump from operating at too low source outlet
temperatures. It is intended for plants that use water as the heat source.
If, during operation, the source outlet temperature drops below the “Source temp min
water”, the pumps and the compressor are switched off for the “Time limit source temp
min” (2822).
Source temp min brine
This function is intended for plants that use the ground as a heat source and is aimed
at preventing the source temperature from dropping excessively. With the exception of
the following 2 points, this function is identical with function “Source temp min water”:
Function 5804 is used to select whether the temperature at the source inlet or source
outlet shall be considered
During the time the floor curing function is carried out, the controller raises
automatically the minimum source temperature by the value set on operating line 2818
The source protection function for brine-to-water heat pumps also applies to setting
“Heat source = external” on operating line 5800.
Switching diff source
prot
After the set maximum source startup time (2821), the source temperature must
exceed the source protection temperature (2815 or 2816) by at least the “Switching diff
source prot” (2817) , enabling the compressor to be switched on when there is a valid
heat request.
Increase source prot
temp
In the case of brine-to-water heat pumps, the controller raises automatically the
minimum source temperature (2816) by the adjustable value “Increase source prot
temp” during the time the floor curing function is performed.
Prerun time source
Before putting the compressor into operation, the source pump (or the fan in the case
of an air-to-water heat pump) must be activated, ensuring that the refrigerant passes
through the evaporator, enabling the sensors to acquire the correct temperature.
Overrun time source
When the compressor is switched off, the source pump (or the fan in the case of an airto-water heat pump) continues to operate for the set overrun time.
Source startup time
max
If, during the adjustable “Source startup time max“, the source temperature does not
reach the required level (2815 or 2816 plus 2817), the heat pump goes to lockout. The
fault must be reset, either manually or automatically.
Time limit source temp
min
Refer to the description of ”Source temp min water“ (2815) or “Source temp min brine”
(2816).
In the event of a heat pump fault, the source pump will be deactivated until the fault is
corrected.
The parameters described above – with the exception of prerun and overrun time
source – have no impact on air-to-water heat pumps.
During “Time limit source temp min“ (2822), the electric immersion heaters installed in
the flow are activated.

Compressor control in plants without buffer or combi storage tank
The settings apply to compressor 1 and – if present – to compressor 2.
Control
If there is no buffer or combi storage tank installed, the compressor is switched
according to the return temperature (B71) and the “Switching diff return temp”
(operating line 2840).
The return temperature setpoint is used for calculating the switch-on or switch-off point.
The return temperature setpoint is calculated based on the required flow temperature
setpoint and the “Differential HC at OT –10 °C“ (5801). The adjustable “Switching diff
return temp“ (2840) lies symmetrically about the calculated return temperature setpoint.

To enable the controller to put the heat pump into operation without control of a buffer

If the return temperature setpoint drops below 30 °C, the switching differential is
reduced in a way that the switch-on point approaches the setpoint. With a return
temperature setpoint of 20 °C, the switch-on point is identical with the return
temperature setpoint.

The calculation of the return temperature setpoint is explained on operating line 5810
(“Differential HC at OT –10 °C”).
The function is not active when heat compensation is switched on.
Compressor control in plants with buffer or combi storage tank
The settings apply to compressor 1 and – if present – to compressor 2.
Control
If a buffer or storage tank is connected to the same controller as the heat pump, the
controller uses sensors B4 and B41 for control of the compressor. The switching
differential (2840) has no impact.
If there is no sensor B41, heat pump return temperature sensor B71 is used.
The setting on operating line 2841 defines whether the minimum compressor running
time (2842) is observed.
As soon as the temperature at both sensors (B4 + B41) drops 1 Kelvin below the flow
temperature setpoint, a heat request is forwarded to the heat pump. This heat request
is maintained until the temperature at both sensors reaches the flow temperature
setpoint.

The heat pump is switched off as soon as the buffer or combi storage tank temperature
has reached the setpoint. The minimum off time is always observed, however, even if
the temperature at the upper buffer storage tank sensor drops below the switch-on
point.
Required sensors:
Bin the case of control with buffer or combi storage tank, the upper buffer storage tank
sensor (B4), the lower buffer storage tank sensor (B41) and the relevant source sensor
must be installed.
If the lower buffer storage tank sensor (B41) is missing, the controller uses the return
temperature sensor (B71) for switching the heat pump off.

If the flow or the return temperature (B21 / B71) exceeds this level, DHW charging or
forced buffer storage tank charging is prematurely aborted and a change to space
heating takes place, provided space heating calls for heat.
In this case, the heat pump continues to operate with no interruption.
If there is no demand for heat from space heating, the heat pump is switched off.
It can resume operation only when the minimum off time (2843) has elapsed, provided
the flow or return temperature (B21 / B71) has dropped below the reduced maximum
switch-off temperature by the amount of the adjustable switching differential (2840).
If an electric immersion heater is installed, DHW charging can be completed.
Otherwise, for DHW charging to be resumed, the DHW storage tank temperature (B3)
must drop by the amount of the DHW switching differential (5024).
If a second compressor is in operation, it is always switched off when the reduced
switch-off temperature is reached, and no status message is displayed. During DHW
charging, or in the case of forced buffer storage tank charging, compressors 1 and 2
are switched off at the same time.

Locking time stage 2
The second stage can be released only when the locking time has elapsed and when
the release integral has been filled. The locking time starts to run on release of the first
compressor. Calculation of the release integral begins only on completion of the locking
time.
The locking time enables compressor 1 to reach a stable operating state before
compressor 2 is switched on. It was preset by the supplier of the compressor.
When compressor 2 is released, compressor 1 is always in operation. Compressor 2
cycles if the output of both compressors together exceeds the demand.
Release integral stage 2
As soon as the locking time for the second compressor stage has elapsed, the
controller starts calculating the heat deficit, if there is any.
If the release integral is filled, the anticipated actual value is calculated on completion of
a further locking time, based on the current temperature gradient.
The second stage is released only if, on completion of the second locking time, the
actual value to be anticipated lies below the required setpoint.

In the case of flow temperature control, the controller uses the flow temperature for

return temperature is used for making the calculation.
To ensure correct switching on of the second stage with storage tank charging (buffer
or DHW storage tank), a flow temperature sensor must be connected. If that sensor is
missing, the controller makes the calculation with a backup value of 0 °C.
Reset integral stage 2
If there is excess heat, the controller generates an integral. As soon as the set value for
the integral is reached, release of the second stage is withdrawn and the first stage
switched off. If the temperature returns to a level below the switch-on point, the first
compressor is switched on again.

If both stages together deliver too much heat, the second stage is immediately switched

Compr sequence
changeover
Automatic changeover of the compressors ensures that both compressors operate
pretty much the same number of hours.
If the difference of operating hours between the first and the second compressor
exceeds the limit (h) set here, the order of startup changes as soon as both
compressors are switched off. This means that compressor 1 becomes compressor 2,
and vice versa. The current compressor sequence appears on operating line 8446.
Electric immersion heater in the flow
Relays K25 and K26 are intended for using an electric immersion heater in the flow.
They are controlled by 2 appropriately configured multifunctional relay outputs QX1 –
QX6.
If both relays are present, the electric immersion heater is controlled in 3 stages (1st
stage K25, 2nd stage K26, and 3rd stage K25 and K26).
If a flow temperature sensor (B21) is connected, it is used for control to the flow
temperature setpoint. The switching differential is 1 °C.
If the flow temperature sensor is missing, but a common flow temperature sensor (B10)
is available, that sensor is used for conrol.
If no flow temperature sensor is present, the electric immersion heater is controlled
based on the return temperature (B71) and the return temperature setpoint. The
switching differential is set with parameter “Switching diff return temp” (2840).

3-stage electric immersion heater, both stages (K25 and K26) are switched on at the
same time.
Control of the electric immersion heater must take place by an external thermostat.
With DHW charging: If the heat pump is not capable of completing DHW charging, the
electric immersion heater is not switched on and DHW charging will be aborted.
Complement to heat pump operation
With this setting, the electric immersion heater is used as described under "Substitute",
and in cases where the heat pump is not capable of satisfying the demand for heat.
In the case of DHW charging, the electric immersion heater is locked, however, except
when the compressor had to be switched off due to the maximum switch-off
temperature, high-pressure or hot-gas problems. In these cases, the electric immersion
heater is released for DHW charging when the maximum permissible number of
charging attempts (2893) has been reached.
With DHW charging: If the heat pump is not capable of completing DHW charging, it will
be completed by the electric immersion heater. In that case, the current DHW charging
temperature is saved when switching to the electric immersion heater occurs.
With diagnostics, the saved temperature appears as “Curr DHW charg temp HP”
(7093).
If there is no control sensor (B21, B10, B71), the electric immersion heater is locked
when controlling to the return temperature sensor and can only be activated via
emergency operation.
Substitute and complement to heat pump operation
In the following cases, setting “Use electric flow” has no impact on the use of the
electric immersion heater:
• With frost protection
• With air-to-water heat pumps during the defrost process
• During active limitation due to too low source temperature (see “Time limit source
temp min” for water-to-water heat pumps (2822))
If the flow switch on the consumer side responds, or if the water pressure is too low, the
electric immersion heater will be switched off.
Locking time electric flow
The electric immersion heater may be switched on only when the locking time after the
compressor start set here has elapsed. If there are 2 compressors, the locking time
starts to run after startup of the second compressor.
The locking time is considered only if the electric immersion heater is used as a
“Complement to HP operation” (2880). It is not taken into consideration when using the
“Substitute” setting.
Release integral
electric flow
When using a 2- or 3-stage electric immersion heater, the stages are released in
accordance with the release and the reset integral (2882 and 2883).
Release integral with “Substitute” setting (2880)
After release of the electric immersion heater’s first stage (K25), the controller
compares the actual temperature value with the switch-on point and generates an
integral based on the heat deficit, if there is any. As soon as the value of the integral
reaches the set maximum value (2882), the second stage is released (K25 off, K26
controls).

The controller continues to compare the actual value of the temperature with the
switch-on point and calculates again the heat deficit in the release integral.
When the release integral reaches the set value (2882), the third stage of the electric
immersion heater is released (K25 fixed on, and K26 controls).
Release integral with setting “Complement HP operation“ (2880)
On completion of “Locking time electric flow“, the controller starts calculating the heat
deficit, if there is any. The first stage of the electric immersion heater (K25) is released
only when the heat deficit has reached the level set here.
For the second and third stage of the electric immersion heater, the locking time is not
taken into consideration, but the release integral must again reach the set value.

(2883).
For a new release, the release integral must be filled again.
Release el flow below OT
The electric immersion heater is released only when the attenuated outside
temperature lies below the temperature set here.
This setting is considered only if the electric immersion heater is used as “Complement
to HP operation” (2880). With the “Substitute” setting, the electric immersion heater is
always released.
Heat pump protection during DHW charging
The heat pump switches off, when the high-pressure switch response during DHW
charging or because the hot-gas or flow temperature approaches its maximum value.
Parameter "Number DHW charg attempts" (2893) is used to select whether charging
shall immediately be aborted or whether the heat pump shall make a certain number of
charging attempts. In the case of several attempts, the heat pump starts the next
charging attempt each time the minimum off time has elapsed.
If the heat pump shall make only one charging attempt or if, after the selected number
of attempts, the DHW has still not reached the required temperature, DHW charging will

diagnostics, the saved temperature appears as “Curr DHW charg temp HP” (7093). The
value is maintained until – due to limitation – the heat pump must again abort DHW
charging.
If the “Curr DHW charg temp HP“ lies below the adjustable value of “DHW charg temp
HP min” (7092) a maintenance message appears.
If the reduced setpoint lies below “DHW charg temp HP min“ and the heat pump can
terminate DHW charging, the controller will not generate a service message.
In the case of sudden setpoint changes, the switch-on point changes to setpoint minus

This function compensates for excess heat and heat deficits.
These can occur in the following situations:
•
Minimum compressor on and off times
•
In the case of low temperature requests, the flow temperature can lie below the
required setpoint, but the return temperature may not drop below the switch-on
point for a longer period of time. In this situation, the heat pump must be
switched on to prevent heat deficits
The controller compares continuously the flow temperature setpoint with the actual
value and integrates excess heat and heat deficits. Differences are compensated for by
extending the compressor on and off times.
If the compressor is not switched on or off due to excess heat / heat deficits, the
controller displays an appropriate status message.
The function can only be used when control is based on the return temperature. In the
case of plants with buffer or combi storage tanks, the setting (on / off) has no impact.
“Compensation heat deficit“ only acts in heating mode. The parameter is inactive in
cooling mode.
The maximum switch-off temperature is given priority over the compensation function.
In the case of sudden setpoint changes, both integrals will be deleted.
Behavior in connection with the floor curing function
When activating the floor curing function, the integral is set to a level representing 1.5
times the predefined value (default setting). If the actual temperature lies at least 2 K
below the required setpoint, the heat pump will immediately be switched on.
If compensation of excess heat / heat deficits shall act only when the floor curing
function is active, the respective setting is to be selected. This means that the
parameter is deactivated in normal heating mode.

Calculation of integral
If a flow sensor (B21) is connected and the heating curve is set to the flow temperature
setpoint, the controller uses the actual flow temperature and the flow temperature
setpoint for computing the integrals.
If sensor B21 is not present and the compressor does not operate, the temperature at
the return sensor (B71) is used and, when the compressor runs, the temperature at
B71 plus parameter “Req temp diff condenser” (2805).
If the heating curves are set to the return (BZ5810), the return temperture sensor (B71)
and the return setpoint are used for calculating the integral.
If that is not the case, the return sensor (B71) and the return temperature setpoint are
used.
In the following situations, the integral is set to 0:
•
•
•
•
No valid temperature request delivered
Setpoint change >2 K
Frost protection for the HP is active
The heat pump has gone to lockout or cannot deliver any heat for a longer
period of time
The heat pump is in active cooling mode
A buffer storage tank is being charged
The function is deactivated.
•
•
•
With active DHW charging, the integral value is frozen in.
In the following example of compensation, excess heat occurs during the minimum
compressor on time. Excess heat is reduced again on completion of the set minimum
compressor off time in that the compressor will not yet be released:

Delay 3-ph current error
The compressor is switched off if the 3-phase current error is constantly present for the
period of time set here. On completion of “Min off time“, the heat pump is switched on
again. If, within “Duration error repetition”, the 3-phase current error occurs again for at
least the delay time, the heat pump will initiate lockout, if the permitted preset number
of faults has been exceeded.
Delay flow switch
source / consumers
The compressor is switched off if the flow switch signal is constantly present during the
period of time set here. On completion of “Min off time“, the heat pump is switched on
again. If, within “Duration error repetition”, the flow switch trips again, the heat pump
initiates lockout, if the permitted preset number of faults has been exceeded.
If the relevant input EX1 – EX7 is configured for use with a pressure switch, a fixed
delay of 3 seconds applies.
Release above OT
The heat pump is released only when the composite outside temperature lies above the
value set here. Below this outside temperature level, the amount of heat required must
be delivered by some other heat source (bivalent operation). This prevents poor
efficiency and thus uneconomical operation of the heat pump.

This defines the behavior of the heat pump in the case of forced buffer storage tank
charging.

The heat pump can be put into operation for forced buffer storage tank charging.
Full charging of buffer

This defines the behavior of the heat pump in the case of full buffer storage tank
charging.
Off
The heat pump remains locked until the buffer storage tank is fully charged by some
other heat source. It is released only when there is not enough heat for satisfying the
current demand (4720).
On
The heat pump is released when the buffer storage tank is fully charged.

Defrost function for air-to-water heat pumps
Defrosting of an iced-up evaporator is effected either with the fan or the compressor by
reversing the process – independent of the outside temperature:
•
•
Above the set outside temperature with the fan
Below the set outside temperature by reversing the process
The example below shows a heat pump in heating mode and in defrosting mode with
process reversal.
Plant in heating mode
In normal heating mode of an air-to-water heat pump, condensation can occur at low
temperatures, causing the evaporator to ice up. This reduces the heat pump’s output
and can lead to low-pressure malfunctions or damage to the evaporator.

Plant in defrost mode (process reversal)
The evaporator is defrosted either with the fan or – as shown in the example below –
with process reversing valve Y22. For process reversal, a HP partial diagram with
process reversing valve (Y22) must be used.
Demand-dependent defrost control ensures that the defrost energy drawn from the
heating circuit in the case of process reversal will be kept at a minimum. During the
defrost process with process reversal, the fan remains deactivated.

Automatic defrost function
When the compressor is in operation, “Duration defrost lock“ (2962) and “Time up to
forced defrost“ (2963) elapse. If the source temperature (B91) drops below the defrost
release temperature (2951), the defrost release function will be released. The heat
pump can change to defrost operation mode after ”Duration defrost lock” at the earliest,
and on completion of “Time up to forced defrost” (2963) at the latest.
When, due to icing up during this period of time, the temperature difference (8477)
between incoming outside air (B91) and evaporator (B84) exceeds the setpoint (8478),
the defrost function is triggered.

When defrosting is successful, the evaporator temperature (B84) rises. If the
evaporator temperature exceeds “Evapor temp defrost end“ (2954 OEM), the defrost
process can be successfully completed and the compressor is switched off during the
dripping time (2965). Then, heating mode is resumed.
Defrost end when
defrosting with the fan
Defrosting with the fan is considered completed when one of the 2 following conditions
is satisfied:
• The temperature difference (8477) between incoming outside air (B91) and
evaporator (B84) is smaller than that set by your supplier
• When defrosting with the fan, the defrost time is reached
The defrost process at low outside temperatures takes more time than at higher outside
temperatures.
Resuming heating
mode and preparing
the next defrost
process
Heating mode is resumed after successful completion of the defrost process either
through process reversal or with the fan. “Duration defrost lock“, “Time up to forced
defrost“ and “Defrost settling time“ (2959 OEM) start to run again.
On completion of “Defrost settling time“ (2959 OEM), “Temp diff defrost icefree“ is
acquired and used to generate the new setpoint (8478).
When there is a heat pump lock pending, any active defrost process is completed.
Manual defrost
Defrosting by reversing the process can also be accomplished manually, either via
input Ex1..7 or via the operating line (7152). With manual defrosting, no consideration
is given to the release temperature (2951) and to “Duration defrost lock“ (2962).

The defrost function can be released only when the source inlet temperature (B91) lies

If the defrost process could not be successfully completed, another attempt is made
after a preheating phase (see “Duration defrost lock”). If, during the number of attempts
set here, it was still not possible to successfully complete the defrost process, the heat
pump is switched off and generates an error message.
For the heat pump to resume operation, the fault must be manually reset.
Duration defrost lock
When the heat pump is switched on in heating mode, “Duration defrost lock” begins to
run. It is at the end of this period of time at the earliest the controller is allowed to start
the next evaporator defrost attempt.
Prerequisite for defrosting is that the source temperature (B91) lies below the set
release temperature (2951).
After a prematurely aborted defrosting attempt (see “Defrost time max“), the heating
water is preheated during the period of time “Duration defrost lock”. If an electric
immersion heater is installed in the flow or in the buffer / combi storage tank, it is
switched on to support preheating. Then, a direct change to defrost mode is made.
Time up to forced defrost
If the heat pump was in operation during the period of time set here, without defrosting
in the meantime, forced defrosting will take place.
The same prerequisite applies here: the source temperature (B91) must lie below the
set release temperature (2951).
Defrost time max
If, in the case of defrost through process reversal, it was not possible to successfully
defrost during “Defrost time max“, the controller aborts the defrost process and tries
again after the preheating phase (see “Duration defrost lock”).
The permitted number of defrost attempts is limited by “Numb defrost attempts max“
(2958).
Dripping time evapor
Before the heat pump is allowed to resume heating mode after successfully defrosting
through process reversal, the “Dripping time evapor“ set here must elapse. The heat
pump resumes operation only on completion of this period of time and the fan is
switched on after a delay time preset by the supplier.
Frost protection for
the heat pump
Frost protection for the heat pump leads to release of the heat pump as soon as the
flow or the return temperature falls below 5 °C. After both sensors have reached the
level of 6 °C, the heat pump’s release is maintained for 5 minutes.
If an electric immersion heater is installed in the flow, it is switched on for this period of
time.
In the case of a 3-stage electric immersion heater (K25 and K26), both relays are
energized.

Cooling
Active cooling
In the case of active cooling, the heat pump operates as a refrigeration machine by
reversing the process in the summer. Process reversal requires a heat pump equipped
with a 4-port valve (Y22) and a HP partial plant diagram which supports this function
(HP18, 19, 38, 39, 50, 51).
Cooling circuit (5711) and refrigeration (5807) can be in the form of a 2- or 4-pipe
system

Passive cooling
with brine-to-water or
water-to-water heat
pump
In the case of passive cooling, cooling is accomplished by letting the cold water
circulate through the system without putting a refrigeration source into operation. For
that purpose, the heat pump’s source pump and the cooling circuit are switched on.
Cooling circuit 1 (5711) and refrigeration (5807) can be in the form of a 4-pipe system.
The HP partial plant diagram must support passive cooling (HP 14, 15, 22, 23, 34, 35,
42, 43).

Active and passive
cooling
In the case of plants that support both passive and active cooling, the controller
switches automatically from passive to active cooling, and vice versa. Simultaneous
active and passive cooling is not possible.
As long as the temperature acquired by the source inlet sensor (B91) lies below the
cooling request, cooling is passive.
If the source temperature exceeds the cooling request, the controller switches to active
cooling.
The HP partial diagram used must support this function (HP 22, 23, 42, 43).
If a source inlet sensor (B91) is used, the temperature acquired by the source outlet
sensor (B92) is used as the changeover criterion.
Parameter setting
examples with active
and passive cooling
The 3 following parameter setting examples show heat pump plant diagrams that make
possible automatic changeover between active and passive cooling mode.
The actively produced cooling energy is delivered to the consumers via the heating /
cooling pipes.
For the passively produced cooling energy, parameter “During compressor operation”
can be used to select indirectly the pipes via which cooling energy shall be delivered to
the consumers:
Passive cooling while the compressor is off
The passive cooling enery is diverted to the heating / cooling pipe.
If there is a DHW request, it is satisfied by the heat pump via the common heating /
cooling pipe. If there is a cooling request at the same time, it cannot be satisfied.
Passive cooling while the compressor is on
Passive cooling is effected via the cooling pipe. If there is a DHW request, it is satisfied
by the heat pump via the heating / cooling pipe. If there is a cooling request at the same
time, it can simultaneously be satisfied via the cooling pipe.
If passive cooling is effected via the heating / cooling pipe, parameter “In passive
cooling mode” (3007) can be used to define whether the condenser pump shall be
switched on or off.
Prerequisites for the 3 examples
• Setting “Heat source” (5800) must read "Brine" or "Water"
• Setting “Refrigeration” (5807) must read “4-pipe system”
• A process reversing valve must be configured

If the return temperature (B71) lies above “Switch-off temp max cooling“, the
compressor must not be put into operation. If it is running, it will be switched off.
On completion of the set pump prerun times – but not before 2 minutes have elapsed –
the pumps are deactivated if the temperatures are still too high.
Another compressor startup attempt is made on completion of the minimum
compressor off time (2843).
This function is only active in the case of active cooling. It has no impact with passive
cooling. For more detailed information about active / passive cooling, refer to page 94.
Source temp min cool
mode (frost protection)
To prevent the formation of ice in the heat exchanger for separating the media in
passive cooling mode, a minimum source temperature can be entered. If the
temperature at the source outlet sensor (B92) falls below the value set with parameter
“Source temp min cool mode”, the consumers will be locked until the source outlet
temperature exceeds the minimum temperature by 1 °C.
SD ch’over cooling pas/act
If the source temperature drops below the cooling setpoint minus the switching
differential set here and the minimum compressor on time has elapsed, the controller
switches to passive cooling.

Electric immersion heaters in the cascade
Many heat pumps are equipped with an electric immersion heater (K25) in the flow
(directly after the condenser). The electric immersion heaters can be of the 2- or 3stage type (K25 and K26).
If all compressor stages of the cascade are released, the electric immersion heater of
the heat pump with first priority is released. Electric immersion heaters are released
according to the same criteria as heat pumps (release and reset integral). The heat
pump reports to the source master when all stages of the electric immersion heater are
released, or when no electric immersion heater is available.

Locking time
The temperature-time integral is a continuous summation of the temperature differential
over time. In this case, the decisive criterion is the difference by which the temperature
lies above or below the common flow temperature setpoint.
Through generation of the temperature-time integral, it is not only the period of time that
is considered, but
the extent of the deviation also. This means that when the crossing is significant, the
supplementary source is released earlier, or locked earlier, than with minor crossings.

The priority circuit for the swimming pool (2065) can impact the storage tank priority of
solar charging and possibly charge the swimming pool before charging the storage
tanks.
Charging prio storage tank
If a plant uses several heat exchangers, it is possible to set a priority for the integrated
storage tanks, which defines the charging sequence.
None
Every storage tank is charged alternately for a temperature increase of 5 °C at a time,
until every setpoint of level A, B or C (see below) is reached. The setpoints of the next
higher level are approached only when all setpoints of the previous level have been
reached.
DHW storage tank
During solar charging, preference is given to the DHW storage tank. At every level A, B
or C (see below), it is charged with priority. Only then will the other consumers of the
same level be charged. As soon as all setpoints of a level are attained, those of the
next level are approached, whereby priority is again given to the DHW storage tank.
Buffer sensor
During solar charging, preference is given to the buffer storage tank. At every level A, B
or C (see below), it is charged with priority. Only then will the other consumers of the
same level be charged. As soon as all setpoints of a level are attained, those of the
next level are approached, whereby priority is again given to the buffer storage tank.

Level
When priority for the swimming pool is activated (2065), the swimming pool is
charged before the storage tanks.
If the preferred storage tank cannot be charged in accordance with charging control,
priority is transferred to the next storage tank or the swimming pool for the period of
time set (e.g. temperature differential between collector and storage tank too great).
As soon as the preferred storage tank (according to setting "Charging prio storage
tank") is again ready to be charged, the transfer of priority will immediately be stopped.

If the parameter is deactivated (---), priority always follows the settings “Charging
priority storage tank”.
Waiting time relative prio
During the period of time set, the transfer of priority is delayed. This prevents relative
priority from intervening too often.
Waiting time parallel op
If solar output is sufficient and solar charging pumps are used, parallel operation is
possible. In that case, the storage tank of the priority model can be the next to be
charged at the same time, in addition to the storage tank to be charged next. Parallel
operation can be delayed by introducing a waiting time. This way, in the case of parallel
operation, switching on of the storage tanks can be effected in steps.
Setting (---) disables parallel operation.

To remove any existing cold water from the primary circuit, operation of the secondary
pump of the external heat exchanger can be delayed.

Summary
B4
A buffer storage tank can be integrated in the plant. It can be
charged via the heat pump, by solar energy or by an electric
immersion heater. In the case of active cooling, it can also be
used for storing cooling energy.
The controller controls heating / cooling and forced charging
of the buffer storage tank, protects it against
overtemperatures and maintains stratification whenever
possible.

Forced charging time

To save electricity costs or to fully charge the storage tank before the heat pump is
locked, forced charging of the buffer storage tank can be triggered. This way, operation
of the heat pump is maintained until the required temperature setpoint for forced
charging (heating / cooling) in the buffer storage tank is reached, or until forced
charging is no longer released, or until the heat pump must be switched off.
When the plant is operating in cooling mode, “Forced charging setp cooling” is used. In
heating mode, the slave point is used for the setpoint. It can be limited with ”Forced
charg setp heat min” (4709) and “Forced charg setp heat max” (4710).
Forced charging can be triggered either via low-tariff input E5 or operating line “Forced
charging time” (4711).
If forced charging is stopped because the heat pump had to be switched off, it will be
resumed as soon as the buffer storage tank temperature has dropped by 5 °C (heating)
or risen by 5 °C (cooling). At this point in time, forced charging must still be released,
and the number of permissible charging abortions must not be exceeded (2893).
Otherwise, the controller waits until forced charging is regularly triggered the next time.
In summer operation, or when all heating circuits are in protective mode, forced
charging is locked.
Forced charging setp
cooling
Forced charging of the buffer storage tank is completed when the “Forced charging
setp cooling“ (4708) is reached. When using setting “---“, forced charging cooling is
deactivated. For forced charging to start, the storage tank temperature at the bottom
must lie at least 2 K above the adjusted setpoint. If there is no sensor at the bottom, the
storage tank sensor at the top is used.

The electric immersion heater ensures DHW charging should the heat pump go to
lockout, should it be off, or should DHW charging be aborted by the heat pump.
If the electric immersion heater must ensure DHW charging because the heat pump
was not able to complete the charging process, the controller saves the DHW
temperature at which the electric immersion heater took over on operating line “Curr
DHW charg temp HP”(7093).
Also, at the changeover point, the switch-on temperature is readjusted. If the DHW
temperature increases due to the electric immersion heater or some other heat source
(e.g. solar), the switch-on point also increases according to the slave pointer principle.
The switch-on point increases to a maximum of current DHW setpoint minus switching
differential. If the DHW temperature falls below the switch-on point, the heat pump will
be put into operation.
Summer
When all heating circuits have switched to summer operation, the electric immersion
heater ensures DHW charging from the next day. This means that the heat pump
remains deactivated during summer operation.
DHW heating via the heat pump is resumed only when at least one of the heating
circuits has switched to heating mode.
In heating mode, the electric immersion heater is operated as described above under

Summary
The controller supports DHW heating via an external heat exchanger. The heating
energy required is delivered by the buffer, DHW or combi storage tank.
A speed-controlled pump (left) or pump with fixed speed plus mixing valve (right) are
used to supply heat to the DHW circuit, depending on demand.

Q34
Q34
When the flow switch (FS) detects flow, sensor B38 ensures that the current DHW
nominal setpoint is maintained. But since heat losses across the external heat
exchanger always occur, parameter 5406 (Min setp diff to tank temp) is used to allow
an adjustable differential for sensor B38. This means: The speed-controlled pump (left)
or the mixing valve (right) tries to reach or maintain the nominal setpoint minus the
setting of parameter 5406 at sensor B38. As soon as the flow switch detects no more
flow, pump Q34 stops.
Configuration
When using the speed-controlled pump without mixing valve (left), pump Q34 must be
configured to multifunctional output QX4mod. Sensor B38 must be assigned to a
multifunctional input Bx.
In that case, flow switch (FS) is automatically assigned to digital input H1.
If, in place of modulating pump Q34, a pump with fixed speed (on / off) is used,
parameters 5530 (Pump speed min) and 5531 OEM (Pump speed max) must be set to
100%.
When using a mixing valve and a pump with fixed speed (right), parameter 6014
(Function mixing group 1) must be configured to “Instantaneous DHW heater“. In that
case, the outputs used with the mixing heating circuit are assigned according to the
table on page 172 (parameter 6014).
In place of the mixing group in the controller, this function can also be assigned to an
extension module. In that case, parameter 6021 or 6022 must be configured to function
“Instantaneous DHW heater“ and the assignment table on page 172 applies
(parameters 6020 and 6021).

Procedure
First, make use of the presetting choices and enter the plant diagram that comes
closest to the plant in question. Then, modify manually the individual partial diagrams to
match them to the actual requirements.
After that, select the extra functions and make the fine-tuning via the operating lines of
the individual parameters.

Preselection
The plant diagrams shown in chapter “Applications“ can be preselected by entering a
diagram number. The plant diagram is the result of preselection plus the connected
sensors.
The sensors contained in the selected plant diagram must be connected to ensure that
automatic sensor identification will not detect some other plant diagram.
Manual setting /
adjustment of partial diagrams
The plant diagrams consist of several partial diagrams.
The required partial diagrams can be used to manually produce the required final plant
diagram.
But it is also possible to modify and adjust partial diagrams of a plant diagram
generated via “Presetting” (5700).
A catalog with partial diagrams, which is separately available, contains the partial
diagrams implemented in the controller – classified according to groups. Also listed in
the catalog are the required operating lines which must be set to produce the
respective partial diagrams, plus the sensors required for the relevant partial diagram.
On operating lines 6212 through 6217 (see page 175), you can check whether the
adjustments led to the right partial diagram. The check number shown there must
accord with the relevant components group.

Separate DHW circuit
In the case of multiboiler plants (cascades), one of the heat sources can temporarily be
used for DHW charging only. When DHW charging is activated, the respective heat
source hydraulically decouples itself from the system by means of the so-called
separate circuit and is not available for space heating during that period of time. On
completion of DHW charging, the heat source is again available for space heating,
which means that it informs the cascade about it.
When the separate circuit is activated with the RVS61.843, condenser pump Q9 is
deactivated when parameter “DHW control element” (5731) is set to "Charging pump”.
The plant diagram below shows a possible application of this function.
This type of plant can also be implemented without using system pump Q14.

The external heat pump can be controlled via the Hx outputs (on / off).
Connection of heat pump sensors to the Siemens controller is optional.
Sensors connected to the controller are used and the associated functions are enabled.
When B71 is connected, use can be made of the controller’s internal compressor stage
control. In that case, the compressor stages must also be connected directly to the
controller.

For the heat pump to be controlled according to the return temperature setpoint, the
latter must be determined first.
For that purpose, the flow temperature setpoint (according to the heating curve) is
reduced by the expected temperature differential across the condenser and used as the
return temperature setpoint.

Diverting valve cool strat2 Y28
Control of optional diverting valve cooling Y28 for changeover to passive cooling. In the
case of simultaneous heating mode, this ensures hydraulic disconnection of the heating
circuit from the cooling circuit.
System pump Q14
The connected pump serves as a system pump for supplying heat to other consumers.
The system pump is put into operation as soon as one of consumers calls for heat. If
there is no heat request, the pump will be deactivated followed by overrun.
Cascade pump Q25
Common pump for all heat sources in a cascade.
Heat generator shutoff valve Y4
If the buffer storage tank holds a sufficient amount of heat, the consumers can draw
their heat from it, and the heat sources need not be put into operation.
Automatic heat generation lock locks the heat sources and hydraulically disconnects
them from the rest of the plant with the help of shutoff valve Y4.
This means that the heat consumers draw energy from the buffer storage tank and
wrong circulation through the heat sources is prevented.
El immersion heater DHW
Using the connected electric immersion heater, the DHW can be charged according to
operating lines “El imm heater optg mode” (5660) and “El immersion heater release”
(5061).
The electric immersion heater must be equipped with a safety limit thermostat!
“El imm heater optg mode” must be appropriately set.

When the contact closes, the temperature setpoint adjusted on operating line 5952 /
5962 is demanded.
Heat request 10V
Heat generation receives heat requests in the form of voltage signals (DC 0...10 V).
The associated setpoint is calculated on the basis of the straight line defined with
operating lines 5953 through 5956 (for H1), or 5963 through 5966 (for H3).
Dewpoint monitor
To detect the formation of condensation in the cooling circuit, a dewpoint monitor can
be connected to input Hx.
If the dewpoint monitor trips, the cooling circuit is immediately switched off.
The cooling is enabled again when the dewpoint monitor reverts to normal and an
adjustable locking time (946) has elapsed.
Flow temp setp inc hygro
To prevent the formation of condensation due to high indoor air humidity, a hygrostat
can be connected to input Hx.
If the hygrostat trips, the flow temperature setpoint is increased by the fixed value of
"Flow temp setp incr hygro" (947). As soon as the hygrostat reverts to normal, the flow
temperature setpoint returns to the "normal value".
Refrigeration request
If the connected contact closes, the controller drives the heat pump to the fixed
temperature setpoint adjusted on operating line 5952 (for H1), 6048 (for H2), or 5962
(for H3). If the refrigeration request made is lower, consideration is given to it.
Refrigeration request 10V
Refrigeration generation receives the refrigeration request in the form of voltage signals
(DC 0...10 V).
The respective setpoint in °C is determined via the linear characteristic which is defined
by 2 fixed points (voltage value 1 / function value 1, and voltage value 2 / function value
2).

Pressure measurement 10V
The controller receives the pressure signal in the form of voltage signals (DC 0...10 V).
The respective pressure value is calculated via the linear characteristic which is defined
by 2 fixed points (voltage value 1 / function value 1 and voltage value 2 / function value
2).
If the pressure value crosses one of the set limit values, an error or maintenance
message is delivered. If the value falls below the critical pressure limit, the heat pump is
shut down.
The values of the maximum, minimum and critical water pressure for H1 can be set
under 6140 OEM...6142 OEM, foür H2 under 6150 OEM…6152 OEM, and for H3
under 6180 OEM…6182 OEM
Rel room humidity 10V
The controller receives the relative humidity signal in the form of voltage signals (DC
0...10 V).
The respective room humidity is calculated via the linear characteristic which is defined
by 2 fixed points (voltage value 1 / function value 1 and voltage value 2 / function value
2).
The controller compares room humidity with the limit values set on operating lines 6137
and 6138 and switches external air dehumidifier K29 connected to an appropriately
defined output QX1 – QX6 (5890 – 5896).
Room temp 10V
The controller receives the room temperature signal in the form of voltage signals (DC
0...10 V). The room temperature in connection with relative room humidity is used to
calculate the dewpoint temperature in the cooling circuit.
If there is no room unit with a room sensor (BSB) connected for heating / cooling circuit
1, the room temperature measured at Hx is also used for room heating / cooling 1
(variant with compensation and room influence).
The respective room temperature is calculated via the linear characteristic which is
defined by 2 fixed points (voltage value 1 / function value 1 and voltage value 2 /
function value 2).
Release swimming pool
This function is to be used to enable direct heating of the swimming pool from
externally via the heat pump and Hx pumps (e.g. with a manual switch).
For direct charging, a release signal is always required at input Hx.
Configuration: Set the function of input Hx to "Release swimming pool" and select the
associated Hx pump at one of the OX outputs.
This function can be used to enable solar heating of the swimming pool from externally
(e.g. with a manual switch) or to define solar charging priority over storage.
Configuration: Set the function of input Hx to "Release swimming pool". For a
description of the function, refer to operating line 2065 "Charging priority solar".

Switch-on command HP stage 1 (heating only)
By closing a contact connected to this input (e.g. by an external controller or a
superposed building automation and control system), stage 1 of the heat pump is put
into operation. It remains in operation until contact Hx opens again or until the heat
pump is shut down by a safety function (e.g. due to high-pressure, low-pressure, or hotgas temperature).
Internal requests, DHW requests and requests via bus are suppressed. No
consideration is given to minimum off time and minimum running time. The prerun and
overrun times of the condenser pump and source pump are taken into account. Normal
defrost is possible.
Switch-on command HP stage 2 (heating only)
By closing a contact connected to this input (e.g. by an external controller or a
superposed building automation and control system), stage 2 of the heat pump is put
into operation. It remains in operation until contact Hx opens again or until the heat
pump is shut down by a safety function (e.g. due to high-pressure, low-pressure, or hotgas temperature).
Internal requests, DHW requests and requests via bus are suppressed. No
consideration is given to minimum off time and minimum running time. The prerun and
overrun times of the condenser pump and source pump are taken into account. Normal
defrost is possible.
Type of contact Hx
NC contact
The contact is normally closed and must be opened to activate the selected Hx
function.
NO contact
The contact is normally open and must be closed to activate the selected function Hx.
The descriptions given on the functions of contact Hx refer to the setting as NO contact.
Function value contact Hx
If input H1, H2, H3 (5950, 6046, 5960) is used as a contact input (”Min flow temp setp”
or “Refrigeration request”), the controller uses the value set here as the setpoint.
The heat pump is controlled constantly at the temperature level set here, either until
contact Hx opens again or until a higher heating / cooling request is delivered.
If several requests for heating or cooling are received at the same time (contact Hx,
DHW or from the controller itself), the highest or lowest of them is automatically
selected.

None
Activation of input Ex has no impact.
Electrical utility lock
Accepts an external locking signal (e.g. from the electrical utiliy) for the heat pump and
locks it. If, in the case of air-to-water heat pumps, locking occurs during defrost, the
controller completes the defrost process before locking the heat pump.
Low tariff
The low tariff signal delivered by the electrical utility can be routed via an Ex input. As
soon as the input is activated, forced charging of the storage tanks is triggered.
The point in time for forced storage tank charging can also be set as a fixed time on
operating lines 4711 and 4712.
Overload compressor 2
Takes the overload message from compressor 2 and shuts it down.
If overload protection responds several times within the preset “Duration error
repetition”, the heat pump initiates lockout and must be manually reset to resume
operation.
When the compressor is started, no consideration is given to overload protection for 3
seconds.
Overload source
Takes the overload message delivered by the source pump / fan. As soon as the
contact is closed, the controller switches the heat pump off. For the heat pump to
resume operation, the minimum off time must have elapsed.
If, within the preset ”Duration error repetition“, “Overload source” responds several
times, the controller locks the heat pump. Operation can only be resumed by making a
reset.
Pressure switch source
Takes the signal delivered by pressure switch source. If, during source pump operation,
the contact closes for at least 3 seconds, and preselected monitoring (always or in
heating mode only) is active, and the prerun time has elapsed, the heat pump is shut
down.
On completion of “Min off time“, the heat pump is switched on again. If the pressure
switch trips again within “Duration error repetition”, the heat pump initiates lockout and
operation can only be resumed by making a reset.
Flow switch source
Takes the signal delivered by flow switch source. If, during source pump operation, the
contact closes for at least the preset delay time (2895), and preselected monitoring
(always or in heating mode only) is active, and the prerun time has elapsed, the heat
pump is shut down and operation can only be resumed by making a reset.
On completion of “Min off time“, the heat pump is switched on again. If the flow switch
trips again within “Duration error repetition”, the heat pump initiates lockout.

Flow switch consumers
Takes the signal delivered by flow switch consumers.
The flow switch is active only when the condenser pump runs and the prerun time has
elapsed. The compressor is not switched on when, on completion of the prerun time
and the preset delay time (2895), the flow switch signal is present.
On completion of “Min off time“, the heat pump is switched on again. If the flow switch
trips again within “Duration error repetition”, the heat pump initiates lockout. Operation
can only be resumed by making a reset.
Defrost manual
Manual defrost is triggered by activating the appropriately defined Ex input.
Common fault HP
Takes a common fault and sets the heat pump to the fault state.
For the heat pump to be switched on again, the common fault must disappear and “Min
off time” (2843) must have elapsed.
Fault soft starter
Takes the fault status signal delivered by an external compressor soft starter.
In the event of an active fault, the controller switches off both compressors.
When the fault status message is no longer present, the heat pump is released again.
3-phase current
For monitoring the 3-phase current, the 3 phases must be connected to inputs Ex5, Ex6
and Ex7 in the correct order (L1, L2, and L3). The controller monitors the correct
temporal order of the 3 phases. Any phase asymmetry, phase interruption or too low
rated voltage of one or several phases is regarded as a 3-phase error.
If a 3-phase error is continuously present during the period of time set under “Delay 3phase error” (2894), the compressor is switched off for the minimum off time. The
controller delivers status message 180: 3-phase current asymmetrical.
If the 3-phase error occurs again within “Duration error repetition” (2889) for at least the
delay time, the heat pump initiates lockout, if the preselected number of errors has
been exceeded. The controller delivers error message 355: 3-phase current
asymmetrical. The heat pump must be manually reset.

Low-pressure switch E9
Input of a low-pressure switch (AC 230 V) upstream of the compressor.

Frost protection on the extension module
Heating circuit
Frost protection for the heating circuit on the extension module operates the same way
as frost protection for the heating circuit connected to the controller (see page 94).
Frost protection for the plant (see page 174) also acts on the heating circuit of the
extension module.
Cooling circuit
If the frost protection function on the extension module responds, its pump (Q24) is
activated and the mixing valve (Y23 / Y24) maintains the frost protection setpoint (10
°C). But the cooling circuit does not send a request to the heat source.
For monitoring frost protection on the extension module, sensor B16 is used. When
there is no flow temperature sensor installed, the frost protection function for the
heating circuit is performed with the common flow temperature (B21).
Frost protection for the plant (see page 174) also acts on the cooling circuit of the
extension module. The function can be activated / deactivated.

Speed-controlled pump
The output signal at UX corresponds to the speed required for the selected pump.
Heat pump setpoint:
The output signal at UX corresponds to the heat pump setpoint for heating or
cooling.
Output setpoint:
The output signal at UX is proportional to the demand for output on the common
flow.
Heating and cooling request:
The output signal at UX corresponds to the common flow temperature setpoint.
Signal logic output UX
The voltage signal can be inverted. It can thus also be used to control pumps with
variable speeds, or temperature request receivers that use inverted signal logic.
Signal output UX
Determines whether the signal shall be delivered as a DC 0...10 V signal or pulse

Time constant building
When the outside temperature varies, the room temperature changes at different rates,
depending on the building's thermal storage capacity (type of building construction).
The above setting is used to adjust the rate of response of the flow temperature
setpoint to varying outside temperatures.
• Example:
>20
The room temperature will respond more slowly to outside temperature variations.
10 - 20
This setting can be used for most types of buildings.
<10
The room temperature will respond more quickly to outside temperature variations.

The range of action of central changeover can be defined.
This concerns:
• Changeover of operating mode via input H (when selecting “Centrally“ on operating
line 6623)
• Summer changeover (when selecting ”Central“ on operating line 6621)
The possible settings are the following:
• Segment: Changeover takes place with all controllers in the same segment
• System: With all controllers, changeover takes place in the entire system (in all
segments). For that, the controller must be located in segment 0!
Summer changeover
The range of action of summer changeover is as follows:
• Local entry:
Local action; the local heating circuit is switched on the basis of operating lines 730,
1030 and 1330
• Central entry: Central action; depending on the setting made on operating line
“Action changeover functions“, either the heating circuits in the segment or those of
the entire system are switched based on operating line 730

• Central entry:
Central action; depending on the setting made on operating line “Action changeover
functions“, either the heating circuits in the segment or those in the entire system are

DHW assignment
Assignment of DHW heating is required only if it is controlled by a heating circuit time
program (refer to operating lines 1620 and 5061).
Settings:
• Local heating circuits:
DHW is only heated for the local heating circuit
• All heating circuits in the segment:
DHW is heated for all heating circuits in the segment
• All heating circuits in the system:
DHW is heated for all heating circuits in the system.
With all settings, controllers in holiday mode are also considered for DHW heating.
Refrigeration request
"Refrigeration request K28" sets the relay parameter at the QX.. for the output of the
refrigeration request.
Depending on the setting (locally / centrally) the request is delivered by the local
cooling circuit or all cooling circuits in the system. This option only applies to the device
with device address 1.
• Local entry:
Consideration is only given to local refrigeration requests
• Central entry:
Consideration is given to all refrigeration requests from the system
Cascade master
When creating a cascade, the controller having address 1 is assigned the role of the
cascade master. That controller then activates the required functionality and displays
the additional operating menus including the cascade-related parameters.
Identification as the cascade master is made either automatically, depending on the
selection made, or can be ready assigned by selecting “Always”.
In the case of a cascaded plant, it is recommended to select “Always” on the cascade
master. This selection ensures that the cascade operating menus and common
functions (e.g. common return temperature control) will not be lost should a power
failure occur.

error.
If indicated in table “Number”, it can be selected how many times the error shall be
reset before the heat pump triggers lockout.
Heat pump operation
This indicates whether or not the heat pump can continue to operate should a fault
occur.
Yes
The heat pump continues to operate although an error message was delivered.
No
Error causes the heat pump to shut down.
No with brine
In the case of brine heat pumps, the error causes the heat pump to shut down; in the
case of water or air heat pumps, the heat pump will continue to operate.
No with water
In the case of water heat pumps, the error causes the heat pump to shut down; in the
case of brine or air heat pumps, the heat pump will continue to operate.
No with air
In the case of air heat pumps, the error causes the heat pump to shut down; in the case
of brine or water heat pumps, the heat pump will continue to operate.
Plant diagram-dependent
Heat pump shutdown depends on the plant diagram currently used.
Alarm messages
The errors are assigned priorities. From priority 5 (that is, priorities 5 - 9), alarm
messages are delivered, which are used for remote monitoring (OCI). In addition, the
alarm relay is set.

Economy mode
During intermediate seasons, the demand for heat can possibly be covered by
ecological heat sources, such as solar or wood-fired boilers. Conventional heat
sources, such as heat pumps or electric immersion heaters, will be locked. This option
can be enabled or disabled via operating line “Economy function“. Using operating line
“Economy function“, the enduser can switch off the heat pump or the electric immersion
heater for any desired period of time.

6.28 Pump kick
To ensure that pumps and valves do not get damaged during off times, they are
operated for short periods of time at regular intervals.
The kick function is triggered every Friday at 10:00 (not adjustable).
The relay outputs for pumps and mixing valves are activated one by one for 30 seconds
at an interval of 1 minute.
With the multifunctional relay outputs QX, it depends on the setting made whether or
not the kick function acts on the relay.
If the pump is speed-controlled, modulation output QX4 (only RVS61) or UX used is set
to the maximum pump speed.

Basic diagrams
The following plant diagrams can be preselected by entering a number (5700). The
plant diagram is the result of preselection plus the connected sensors.
The sensors contained in the selected plant diagram must be connected to ensure that
automatic sensor identification will not detect some other plant diagram. Components
shown with broken lines are optional.
To reach the plant diagram in the case of applications with RVS41.813, extension
modules AVS75.300 (max. 2) must be added on certain applications.
