setpoint
Heating curve slope
The heating curve
(720,1020,1320)
generates the flow temperature setpoint, which is used to maintain a certain flow
temperature level depending on the prevailing weather conditions.
Notes:

An outside temperature probe model QAC34 should be added (supplied separately from the boiler and not
included in the price).

The set heating curve is based on a room temperature setpoint of 20°C. If this setpoint is changed, the
heating curve automatically adapts to the new value.
Additional parameters for the heating curve:
o
Heating curve displacement (721,1021,1321): 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. Default
value “0”.
o
Heating curve adaption (726,1026,1326): Adaption of the heating curve is used by the controller to
automatically adapt the heating curve to the prevailing weather conditions. In that case, a readjustment of
heating curve slope and parallel displacement is not required. An outside temperature sensor must be
connected and a correct adjustment of the “Room influence” (750,1050,1350). Default value “Off”.
Summer/winter heating limit
The summer/winter heating limit (730,1030,1330) is used to switch the heating on and off in the course of the year,
depending on the outside temperature. In Automatic operation, switching on/off takes place automatically, so there is
no need for the user to do this manually.
The Summer/winter changeover function switches the heating off when the attenuated outside temperature exceeds
the adjusted changeover temperature, in the last 24 hours. The heating system is switched on again (winter mode)
when the attenuated outside temperature drops 1 ºC below the adjusted value.
