36 Return temperature inuence - min. limitation

Circuit Setting range Factory setting

I -9.9 ... 0 ... 9.9 0.0

Set the inuence from the return temperature on the desired DHW

charging temperature.

Set the inuence of the min. return temperature

limitation (set in line 30 or lines 31-34).

Inuence higher than 0:

The desired DHW charging temperature is

increased, when the return temperature gets

below the set limit.

Inuence lower than 0:

The desired DHW charging temperature is

decreased, when the return temperature gets

below the set limit.

Inuence

Min. limitation > 0

Return limit Return temp.

Min. limitation < 0

Example

The limitation temperature is set to 25 °C.

The inuence is set to 2.0.

The actual return temperature is 2 degrees too low.

Result:

The desired DHW charging temperature temperature is changed

by 2.0 x 2 = 4 degrees.

Normally, the setting in line 36 is 0 in district heating systems

because a lower return temperature is acceptable.

Typically, the setting in line 36 is higher than 0 in boiler systems to

avoid a too low return temperature (see also line 35).
