72 Compressor sequence
Circuit Setting range
II ON / OFF
To ensure an even load of two compressors in a heat pump, one
compressor is active all the time and the other compressor is cut-
in when needed. After midnight the role of the two compressors
is interchanged. The currently active compressor corresponds to
heat pump stage I.
ON: The changeover sequence is active.
OFF: The changeover sequence is deactivated.
78 Desired temperature for anti-bacteria function
Circuit Setting range
II OFF / 1 ... 100 °C
Set the desired temperature for the anti-bacteria function.
The DHW will be charged once a week at the set temperature
to protect against bacteria. The function is always active on
Mondays from 00:00 and the DHW is charged according to the
period set in line 80.
OFF: The anti-bacteria function is not active.
1 ... 100:
The anti-bacteria function is active at the
desired temperature.
80 Anti-bacteria function period
Circuit Setting range
II 5 ... 250 min.
Set the period for the anti-bacteria function. When the set time
expires, the anti-bacteria function is stopped.
5 ... 250:
The anti-bacteria function is active for the
set period.
The function is activated in line 78 by setting the desired anti-
bacteria temperature.

85 Application type selection (heat pump stage II)
Circuit Setting range
II
Choose whether the heat pump is to be operated with one
compressor and additional electric heater / boiler or with two
compressors. At too low outdoor temperatures (section 27), heat
pump stage II is activated. In heat pump stage II either the electric
heater, boiler or the second compressor is activated.
0:
Heat pump / electric heater in the flow:
During bivalent operation the heat pump is
cut-out and the electric heater cut-in. Pump
P2 remains ON to circulate the heat.
1: Heat pump / electric heater in hydraulic
shunt or heat pump / boiler (oil / gas):
During bivalent operation the heat pump
and pump P2 are cut-out. The electric
heater or boiler is cut-in and heats up the
water in the hydraulic shunt.
2: Heat pump with two compressors:
During monovalent operation the second
compressor is cut-in. Pump P2 remains ON
to circulate the heat.
86 Pre-run of the ground coil pump P3
Circuit Setting range
II 1 ... 250 sec.
The cut-in command for the compressor will be given when the
set time has elapsed.
Set the desired pre-run time.
91 Forced standstill period of compressor I after cut-out
Circuit Setting range
II 0 ... 99 min.
The forced standstill period time is the min. time that compressor I
must be cut-out before it is cut-in again.
Set the desired time for forced standstill period of
the heat pump (compressor I).
92 Forced standstill period of compressor II after cut-out
Circuit Setting range
II 0 ... 99 min.
The forced standstill period time is the min. time that compressor
II must be cut-out before it is cut-in again.
Set the desired time for forced standstill period of
the heat pump (compressor II).
If the heat pump only has one compressor, and an electric heater
or a boiler is present, a cut-in delay of 0 min. must be chosen in
line 92.
