Mounting and installation
3.1 Regulations
Electrical installation
• Prior to installing the units, power must be turned off
• The connections for mains and low-voltage are separated
• The wiring must be made in compliance with the requirements of safety class II. This
means that sensor and mains cables must not be run in the same duct
3.2 Basic units 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 segregated from low-voltage cables (sensors)
observing a distance of at least 100 mm
Mounting location
• Boiler
• Control panel
• Housing for wall mounting

The room unit should be located in the main living room while giving consideration to
the following points:
• The place of installation should be chosen so that the sensor can capture the room
temperature as accurately as possible without getting adversely affected by direct
solar radiation or other heat or refrigeration sources (about 1.5 meters above the
floor)
• In the case of wall mounting, there must be sufficient clearance above the unit,
enabling it to be fitted and removed
When the unit is removed from its base, power is cut off so that the unit is out of
operation.

The switching times can be set in a combined way, that is, either commonly for several
days or in the form of separate times for individual days. When preselecting groups of
days like for instance Mo...Fr and Sa...Su that use the same switching times, setting of
the switching programs is simplified.

Heating curve slope
Heating curve displacement
Heating curve adaption
The heating curve is used to generate the flow temperature setpoint, which is used to
maintain a certain flow temperature level depending on the prevailing weather
conditions. The heating curve can be adjusted with a number of settings, thus matching
heat output and room temperature to individual needs.
Heating curve slope
As the heating curve slope is raised, the flow temperature increases the quicker the
lower the outside temperature or, in other words, if the room temperature is not correct
at low outside temperatures but correct at higher outside temperatures, the heating
curve slope requires readjustment.
Increase adjustment:
Raises the flow temperature, especially when outside
temperatures are low.
Decrease adjustment:
Lowers the flow temperature, especially when outside
temperatures are low.
The programmed heating curve is based on a room setpoint of 20°C. If the room
setpoint is adjusted, the heating curve automatically adapts to the new value.

displacement
Heating curve adaption
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 with the help
of the parallel displacement.
Adaptation of the heating curve is used by the controller to automatically adapt the
heating curve to the prevailing conditions. In that case, a readjustment of heating curve
slope and parallel displacement is not required. It can only be switched on or off.
To assure this function, following must be observed:
• A room sensor must be connected.
• The ”Room influence“ setting must be selected 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).

compensation.

Pure weather compensation *
Weather compensation with room

* Outside sensor required.
Weather compensation
only
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,
facilitating more accurate room temperature control. The effect of the 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:
Good reference room conditions
Approx. 60 %
Approx. 20 %
Unfavorable reference room
To activate the function, following must be considered:
• A room sensor must be connected.
• “Room influence“ must be set to a value between 1 and 99 %.
• 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).

During quick setback, the heating circuit pump is deactivated and, in the case of mixing
valve circuits, the mixing valve is fully closed.
• Function with room sensor:
When using the room sensor, the function keeps the heating switched off until the room
temperature has dropped to the level of the Reduced setpoint or the frost level.
When the room temperature has fallen to the Reduced level or the frost level, the
heating circuit pump will be activated and the mixing valve will be released.
• Function without room sensor:
Quick setback switches the heating off for a certain period of time, depending on the
outside temperature and the building time constant.

The function is used primarily in connection with heating systems with only little spare

long at low outside temperatures. When the Reduced setpoint is raised, the rooms are
prevented from cooling down to too low levels, thus shortening the heating up time
when changing to the Comfort setpoint.

In the case of heating plant with pump heating circuits, the flow temperature of the
heating circuit can be higher than the flow temperature demanded by the heating curve,
due to requests from other heat consumers (mixing heating circuit, DHW charging,
external heat demand), or a parameterized minimum heat generation temperature. As a
result of this too high flow temperature, the pump heating circuit would assume
excessive temperatures.

A low limit can be defined for the cooling flow temperature.
The limit curve is determined by defining two fixed points.
There is also a low limit for the resulting flow setpoint, which must not fall below 5 °C.
Min. flow setpoint
This defines the lowest permissible flow temperature at a composite outside
temperature of 25°C/25°C.

Compensation variants
When a room temperature sensor is used, there is a choice of different types of
compensation.

− − −%
1…99 %
Weather compensation only *
Weather compensation with room
influence
100 %
Room compensation only
* Outside sensor required.
Weather compensation
only
The flow temperature is calculated via the cooling curve as a function of the composite
outside temperature.
This type of compensation requires correct adjustment of the heating curve, since in
this case, the control does not take account of 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. In this way, account is taken of room
temperature deviations, to facilitate more accurate room temperature control. The effect
of the 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 selected 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).
Room compensation only
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 following
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
position).

Room temp limitation
The room temperature limitation function makes it possible to disable the cooling circuit
pump if the room temperature falls by more than the programmed offset from the
effective room setpoint (with summer compensation, operating line 920).
The cooling circuit pump is activated again as soon as the room temperature returns to
a level above the current room temperature setpoint.

Mixing valve cooling offset
The refrigeration demand from the mixing valve circuit to the heat source is reduced by
the programmed value. The purpose of this reduction is to enable the mixing valve
controller to compensate for the fluctuation in temperature caused by the heat source
(2-point control action).
Actuator type
2-position
The controller drives the actuator with only 1 relay output. When the output delivers a
signal, the valve opens. When there is no signal, the valve will close automatically.
3-position
The controller drives the actuator with 2 relay outputs. 1 of the outputs is used for
opening the valve and 1 for closing the valve.
Switching differential 2pos
For the 2-position actuator, the "2-position switching differential" must also be adapted.
Three-position actuators are not affected by the switching differential.
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 effect on two-position actuators.
Mixing valve in heating

Defines the position of the mixing valve (Y1/Y2) when heating mode is active.
This parameter has no effect in systems with hydraulically separate heating and cooling
circuits.

When the connected dewpoint monitor detects the formation of condensation it
closes the contact, thereby deactivating the cooling.
The "dewpoint monitor locking time" set here starts running as soon as the contact reopens. Cooling can only start after expiry of this locking time.
The dewpoint monitor must be assigned to the H.. input as "dewpoint monitor".
Flow setpt increase hygro
To prevent the formation of condensation due to excess indoor air humidity, a hygrostat
can be used to implement a fixed increase in the flow temperature.
As soon as the air humidity rises above the value set on the hygrostat, the contact is
closed and the flow temperature setpoint is increased by the amount programmed here.
The hygrostat must be assigned to the H.. input as "Flow setpt increase hygro".
Start flow increase at R.H.
To prevent the formation of condensation due to excess indoor air humidity, a
0…10 V humidity measurement can be used to implement a proportional increase in
the flow temperature.
If the relative humidity in the room exceeds the value defined by "Start flow increase at
R.H." the flow temperature setpoint is increased proportionally. The start of the increase
(BZ 948) and the maximum increase (BZ 947) can be programmed.
The humidity sensor must be assigned to the H.. input as "Relative room humidity 10V".

The function can be disabled with the setting – – –.
The humidity sensor must be assigned to an H.. input as "Relative room humidity 10V",

Pump H1 Q15
Pump H1 can be used for an additional consumer. Together with an external request
for heat at input H1, it is possible to operate an air heater or similar.
Alarm output K10
The alarm relay signals faults, should they occur.
Switching on takes place with a delay of 2 minutes.
When the fault is corrected, that is, when the error message is no longer present, the
relay will be deenergized with no delay.
If the fault cannot immediately be corrected, it is still possible to reset the alarm relay.
This is made on operating page “Faults“.
2nd pump speed
This function facilitates the control of a 2-speed heating circuit pump, allowing the
pump’s capacity to be lowered in Reduced mode (e.g. during night setback). In that
case, multifunctional relay QX is used to activate the 2nd pump speed in the following

Heat request K27
As soon as there is demand for heat, output K27 is activated.
Refrig demand K28
As soon as there is refrigeration demand, output K28 is activated.
In the case of the device with address 1, a refrigeration demand from the system can
activate output K28. For this purpose, operating line 6627 "Refrig demand K28" on the
operating page "LPB system" must be set to "Centrally".
Dehumidifier K29
An external dehumidifier can be enabled if the indoor air humidity rises. In this case, a
humidity sensor must be connected to the H… input.
The function of the dehumidifier depends on the cooling functions.
The operation of the dehumidifier is not affected by operating modes, holiday programs,
occupancy buttons etc.
Diverting valve, cooling Y21
With common distribution to the heating and cooling circuits, the inputs/outputs are
always on the mixing valve group on the basic unit. For a 4-pipe system, diverting valve
Y21 is also required.

• Heating circuit
The operating modes of the heating circuits are switched to Protection mode via the
H… terminals (e.g. using a remote telephone switch).
• DHW
DHW heating is locked only when using setting 1: HCs+DHW.
Heat generation lock
The heat source is locked via the H… terminals.
All temperature requests made by the heating circuits and by DHW will be ignored.
Frost protection is maintained.
The chimney sweep function can be activated although the heat generation lock is
switched on.
Error/alarm message
Input H1 generates a controller-internal error message.
If the “Alarm output” (relay outputs QX2-4, operating lines 5891 – 5894) is appropriately
configured, the error message will be forwarded or displayed by an additional contact
(e.g. an external lamp or horn).

Excess heat discharge
Active dissipation of excessive heat enables an external heat source to force
consumers (heating circuit, DHW storage tank, Hx pump) to draw excessive heat by
delivering a forced signal.
The parameter “Excessive heat draw“ can be used to determine for every consumer
whether or not it should take account of the "forced" signal, and hence whether or not
that consumer should participate in the dissipation of heat.
• Local effect
When using LPB device address 0 or >1, excessive heat dissipation only acts on the
local consumers connected to the controller.
• Central effect (LPB)
When using LPB device address = 1, excessive heat dissipation also acts on the
consumers connected to the other controllers in the same segment.
The distribution of excessive heat from segment 0 across other segments of the system
is not possible.
Dew point monitor
The dewpoint monitor detects the formation of condensate. If the dewpoint monitor
responds to condensation, the cooling switches off immediately.
The cooling is enabled when the monitor is no longer signalling condensation and when
a definable "locking time" (operating line 946) has expired.
Flow setpoint increase, hygrostat
If the hygrostat responds, the flow setpoint is increased by the fixed value defined in
"Flow setpt increase hygro" (operating line 947). As soon as the hygrostat reverts to
normal, the flow setpoint returns to the "normal value".
Refrigeration demand
The refrigeration demand is transmitted to the refrigeration generating plant via a
contact.
The setpoint must be set via operating line 5952.
Heat request 10 V
Heat generation receives heat requests in the form of voltage signals (DC 0...10V).
The linear characteristic curve is defined via two fixed points (voltage value 1 / function
value 1 and voltage value 2 / function value 2).
Refrig demand 10V
Refrigeration generation receives the refrigeration demand in the form of a voltage
signal (DC 0...10 V).
The linear characteristic curve is defined via two fixed points (voltage value 1 / function
value 1 and voltage value 2 / function value 2).
Pressure measurement 10V
The voltage signal present at input H… is converted into a linearized pressure value.
The linear characteristic curve is defined via two fixed points (voltage value 1 / function
value 1 and voltage value 2 / function value 2).
Relative room humidity 10V
The voltage signal present at input Hx is converted into a linearized relative humidity
value. This is used for the dewpoint calculation and dewpoint protection functions of the
cooling circuit and for control of the dehumidifier.

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).

Assignment of DHW
heating
Assignment of DHW heating is required only if it is controlled by a heating circuit
program (refer to operating lines 1620 and 5061).
Settings:
• Local HCs:
DHW is only heated for the local heating circuit
• All HCs in the segment:
DHW is heated for all HCs in the segment
• All HCs 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 demand
"Refrigeration demand K28" sets the relay parameter on the QX.. for the output of the
refrigeration demand.
Depending on the setting (local/central) the demand is transmitted by the local cooling
circuit or all cooling circuits in the system. This option applies only to the device with
device address 1.
Ext source with eco mode
Economy mode can be selected from menu ”Special operation / service” (operating line
7139).
In Economy mode, external heat sources on the LPB are operated as follows:
Off:
Remains locked
DHW only:
Released for DHW charging
On:
Always released.

This setting defines the impact of the system time on the controller’s time setting. The
impact is as follows :
• Autonomously: The time of day on the controller can be readjusted
The controller's time of day is not matched to the system time
• Slave without remote adjustment: The time of day on the controller cannot be
readjusted
The controller's time of day is constantly and automatically matched to the system
time
• Slave with remote adjustment: The time of day on the controller can be readjusted;
at the same time, the system time is readjusted since the change is adopted from the
master.
The controller's time of day is still automatically and constantly matched to the
system time
• Master: The time of day on the controller can be readjusted
The time of day on the controller is used for the system. The system time will be
readjusted

Simulation outside temp
To facilitate commissioning and fault tracing, outside temperatures in the range from –
50 to +50°C can be simulated. During simulation, the actual, the composite and the
attenuated outside temperature will be overridden by the set simulated temperature.
During simulation, calculation of the 3 mentioned outside temperatures continues and
the temperatures are available again when simulation is completed.
The function is deactivated by setting -.- on this operating line, or automatically after a
timeout of 1 hour.
