Service parameter(s) 22-24
22 Pump exercise
Circuit Setting range
I / II ON / OFF
Exercises the pump to avoid blocking in periods without heat
demand.
ON: The pump is switched ON for 1 minute every
third day around noon.
OFF: The pump exercise is not active.
23 Valve exercise
Circuit Setting range
I ON / OFF
Exercises the valve to avoid blocking in periods without heat
demand.
ON: The valve receives a signal to open and close
every third day around noon.
OFF: The valve exercise is not active.
24 Gear motor / thermo actuator
Circuit Setting range
I ON / OFF
Choose the actuator type for your valve.
ON: Gear motor
OFF: Thermo actuator (ABV type)
Control parameters (lines 4-7) are overruled if thermo actuator is
chosen (OFF).

52 Closed valve / normal operation
Circuit Setting range
I ON / OFF
The mixing circuit can be closed during DHW heating.
ON: The valve in the mixing circuit is closed*
during active DHW heating.
OFF: The flow temperature control in the mixing
circuit remains unchanged during active
DHW heating.
*) The desired flow temperature is set to 10 °C.
For the DHW systems 10.1, 10.2, 10.5 and 10.7, priority operation =
ON is to be chosen as DHW is given priority over heating.
For heating systems 10.6 and 10.9, both settings can be chosen.
However, there must be stored enough energy in the tank if
parallel operation = OFF is chosen.
For heating system 10.6 (2 pumps instead of changeover valve),
it is possible to choose parallel operation = OFF without any
restrictions.
71 Min. ON-time of heat pump stage I
Circuit Setting range
II 0 ... 9 min.
Set the minimum operation time for the heat pump (compressor).
Even if the max. temperature at sensor S4 has been exceeded,
the compressor will keep running until the set min. ON-time has
elapsed.
0: The function is deactivated
1 ... 9: Min. ON-time of the heat pump
(compressor)
Heat pump stage I normally refers to compressor I. However, if
the setting ON is chosen in line 72, Compressor sequence, this will
apply to either of the two compressors which is currently active.
