Set the time constant for the sensor S1 input. A low setting
is equivalent to a fast sampling time and a high setting is
equivalent to a slow sampling time.

43 Parallel operation of DHW and heating circuits
Circuit
Setting range
Factory setting
I
OFF / 1 ... 99 K
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 II) can drop before the desired
heating temperature (circuit I) has to be
decreased.

Time
Parallel operation with decreased
heating temp.
If the actual DHW temperature deviates more than the set value
(line 43), the gear motor M1 in the heating circuit will close to
such an extent that the DHW temperature stabilizes at the lowest
acceptable value.
52 Closed valve / normal operation
Circuit
Setting range
Factory setting
I
ON / OFF
OFF
The heating circuit can be closed when the controller acts as slave
and when DHW charging is active in the master.
ON:
The valve in the heating circuit is closed*
during active DHW charging in the master
controller.
OFF:
The flow temperature control remains
unchanged during active DHW charging in
the master controller.
*) The desired flow temperature is set to 10 °C.
The setting in line 52 must be considered if this controller is a
slave.
