37  Time constant for return temperature limitation

Circuit

Setting range

Factory setting

I / II

OFF / 1 ... 50

25 / 25

Controls how fast the actual return temperature adapts to the 

desired return temperature limitation.

Adjust the time constant for the return limitation. 
The setting will eliminate the difference
between the acceptable and the actual return
temperature. 
The difference is integrated to adjust the desired 
flow temperature.

OFF:

    The desired flow temperature will not be 

adjusted any further.

1: 

 

 The desired flow temperature will be 
adjusted quickly.

50: 

   The desired flow temperature will be 

adjusted slowly.

43   Parallel operation of DHW and heating circuits 

Circuit

Setting range

Factory setting

I / II

OFF / 1 ... 99 K

OFF / OFF

Choose whether the heating circuit is to operate in dependence of 

the DHW circuit.

OFF:

   Independent parallel operation, i.e. the 

DHW and the heating circuits operate 
independently of each other. It makes 
no difference whether the desired DHW 
temperature can be reached.

1 ... 99:

 

 Dependent parallel operation, i.e. the 
desired heating temperature depends on 
the DHW demand. 

 

Choose how much the DHW temperature 
(circuit   III) can drop before the desired 
heating temperature (circuit I / II) has to be 
decreased.

Parallel operation with decreased 

heating temp.

If the actual DHW temperature deviates more than the set value 
(line 43), the gear motors M1 / M2 in the heating circuits will close 
to such an extent that the DHW temperature stabilizes at the 
lowest acceptable value.
