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
• For wiring, the requirements of safety class II must be satisfied. Sensor and power
cables must not be run in the same cable 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.

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 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.

Heating curve
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.

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
Deviations of the actual room temperature from the setpoint are acquired and taken into
account when controlling the temperature. Heat gains can thus be considered,
facilitating 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 %
Good reference room
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).
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 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 thermostatic radiator valves in the reference room (mounting
location of the room sensor). (If such valves are present, they must be set to their

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 boiler temperature. As a result of
this too high flow temperature, the pump heating circuit would assume excessive
temperatures.

operating line 3544; the other boilers are then switched on and off in the same order as
the LPB device addresses.
Order according to the number of operating hours
On completion of the number of hours set, the boiler sequence in the cascade changes.
It is always the boiler with the next higher device address which assumes the role of the
lead boiler.

Level
When priority for the swimming pool is activated (operating line 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. too great temperature differential between collector and storage tank).
As soon as the preferred storage tank (according to setting "Charging priority storage
tank") is again ready to be charged, the transfer of priority will immediately be stopped.
If the parameter is off (---), setting Charging tank priority is used as a rule.
Waiting time relative prio
During the period of time set, the transfer of priority will be delayed. This prevents
relative priority from intervening too frequently.
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
simultaneously charged, 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 (---) switches off parallel operation.

To remove any existing cold water in the primary circuit, operation of external heat

condensing boiler, leads to higher efficiency.

Partial charging setpoint
By hydraulically decoupling the lower buffer storage tank section, the chargeable
storage volume is reduced. As a result, the upper storage tank section is charged in a
shorter period of time. The lower storage tank section is only charged when charging of
the upper section is completed.
As soon as the temperature acquired by the temperature sensor (B4/B42) reaches the
setpoint of partial charging, the diverting valve change over to “through-port” and the
rest of the storage tank is charged also.
For changeover, a fixed switching differential of ¼ °C is used.
If the slave pointer is higher than the adjusted setpoint of partial charging, charging to
the slave pointer value takes place.

temperature setpoint. If the boiler temperature stays in the neutral zone for more than
16 seconds, the neutral zone becomes active and positioning pulses are no longer
delivered. As soon as the boiler temperature leaves the neutral zone again, control is
resumed. If the boiler temperature does not stay long enough in the neutral zone,
positioning pulses will also be delivered within the neutral zone.

2 x 1 cascade
The 2x1 cascade is a special configuration of the basic unit, where the 2-stage boiler is
operated as 2 cascaded 1-stage boilers.
Due to the temperature differential between boiler temperature setpoint and boiler
temperature sensor B2 (common, mandatory cascade flow temperature sensor),
switching on / off of the lag boiler (release and reset integral) takes place according to
the control of a 2-stage burner. The same parameters are used.
If a boiler pump is required, QX1 and QX2 (operating lines 5890 and 5891) must be
appropriately set.
A common boiler pump can be operated at any other multifunctional relay output QX
parameterized as boiler pump Q1. The boiler pump of the lead boiler is always mapped
on these outputs.
With the configuration of the 2x1 cascade (parameter “Type of heat source”), the
following outputs and functions will be ready used or assigned.

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).
Minimum flow temperature setpoint TVHw
The adjusted minimum flow temperature setpoint will be activated via terminals H1/2
(e.g. an air heater function for a warm air curtain) closes its contact.
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.
Using parameter “Excessive heat draw“, it is possible to select for every consumer
whether or not the forced signal shall be considered, thus deciding whether or not the
consumer shall contribute to 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.

Chimney sweep function
The burner will be switched on. To ensure continuous burner operation, the only switchoff point used is the boiler temperature's maximum limitation (TKmax).
First, all connected loads will be locked, enabling the boiler temperature to reach the
setpoint of 64 °C as quickly as possible.
When the minimum temperature of 64 °C is attained, the available heating circuits are
switched on one by one, using a dummy load, to make sure that the heat generated by
the boiler is drawn off so that the burner will remain in operation.
For safety reasons, maximum limitation of the boiler temperature (TKmax) remains
active as long as the chimney sweep function is active.
