Description
Operator unit 1 : The control system unit is installed on the boiler.
Room unit 1 : The control system unit is configured as a room tem­
perature unit for heating circuit 1.
Room unit 2 : The control system unit is configured as a room tem­
perature unit for heating circuit 2.
Room unit 3 : The control system unit is configured as a room tem­
perature unit for heating circuit 3.
As Room Temperature Unit 1, the action of the control system unit can
be assigned to CH1 or to two heating circuits:
Temps / mode CH1
Central heating 1 and 2
Central Heating 1 and 3
All central heatings
Locally : The room temperature unit controls only the respective

Parameter Description
Frost protection
setpoint
Heating curve Heating curve gradient: The regulator calcu­
slope lates the flow temperature set point which is
used for the control system, according to out­
side weather conditions.
Summer/winter Limit temperature for switching between Heat­
heating limit ing/Protection mode. Triggers or shuts down
the heating in the course of the year according
to variations in outside temperature. This
switch is made automatically in Automatic
Mode.
24-hour heating The heating is shut down when the outside
limit temperature is equal to the room temperature +
parameter 732 (deactivated in Comfort mode).
Flow temp setpoint The flow set point calculated is limited by the
min set value.
Flow temp setpoint The flow set point calculated is limited by the
max set value.
Flow temp setpoint The set flow value is applied in room tempera­
room stat ture thermostat mode. ' ---' the boiler is running
