CALLING UP THE MACHINE STATUS
Type of heat pump Type of heat pump
Software version of the heating and heat pump
regulator
Bivalent level Bivalent level:
1 = a compressor may operate
2 = two compressors may operate
3 = additional heat generator
may operate as well
Operation mode Current operation mode:
Heating
Domestic hot water
Defros
Only for output-controlled heat pump:
Current capacity Heating output currently provided by
the output-controlled compressor.
This heating output can be used to set
the overow valve in a storage tank
integrated in series according to the
setting diagram in the unit instructions.
Capacity demand Required output for output-controlled
compressor controlled by the heating
and heat pump controller.
Software version SEC Current software version of the inverter
controller of the output-controlled heat
pump
