Circuit Setting range Factory setting
I -9.9 ... 0 ... 9.9 0.0
Set the inuence from the return temperature on the desired DHW
charging temperature.
Set the inuence of the max. return temperature
(set in line 30).
Inuence higher than 0:
The desired DHW charging temperature is
increased, when the return temperature gets
higher than the set limit.
Inuence lower than 0:
The desired DHW charging temperature is
decreased, when the return temperature gets
higher than the set limit.
Inuence
Max. limitation > 0
Limit Return temp.
Max. limitation < 0
Example
The limitation temperature is set to 25 °C.
The inuence is set to -2.0.
The actual return temperature is 2 degrees too high.
Result:
The desired DHW charging temperature is changed by -2.0 x 2 =
-4 degrees.
Normally, the setting in line 35 is lower than 0 in district heating
systems to avoid a too high return temperature.
Typically, the setting in line 35 is 0 in boiler systems because a
higher return temperature is acceptable (see also line 36).
