Reduced setp increase start
(800, 1100, 1400)
Red setp increase end
(801, 1101, 1401) For a relatively small required heating output, the reduced room setpoint can be
raised for cold outside temperatures. The increase is dependent upon the outside
temperature. The lower the outside temperature is, the higher the reduced set-
point for the room temperature is raised. The start of the increase and the end
point can be set. Between these two points there is a linear increase of the "re-
duced setpoint" up to the "comfort setpoint".

Continuous pump operation
(809, 1109, 1409) Using the continuous pump operation function switching off the pump can be
suppressed by the quick setback and when reaching the room set point (room
thermostat, room sensor or room model)
-
No : the heating circuit pump /boiler pump can be switched off by quick setback
or reaching the room set point
- Yes : the heating circuit pump/boiler pump remains switched on even during
the quick setback and after reaching the room set point
Overtemp prot pump circuit
(820, 1120, 1420) This function prevents overheating of the pumped heating circuit by switching-
on and switching-off the pump, if the flow temperature is higher than the flow
temperature required according to the heating curve (e.g. in case of higher de-
mands of other consumers).
Mixing valve boost
(830,1130, 1430) The heat demand of the mixer heating circuit to the generator is superelevated
above the set value here. This boost should be achieved so that the temperature
fluctuations can be corrected with the mixer valve.
Actuator running time
(834, 941, 1134) For mixing circuits, a kick-start of the mixer drive is carried out after a pump kick-
start (Pump is OFF). In this case, the mixer will be controlled in direction OPEN
and CLOSED.
The time of activation in direction OPEN corresponds to the drive running time.
