Procedure Explanations and references
External heat generator
Operating mode, external
heat generator
■
Not active
Demands cannot be sent to the external heat generator.
■
Heating only
Room heating via the external heat generator; no room cooling
Note
DHW is always heated by the integral instantaneous heating water heater.
Operating mode
■
Mono mode
Heat generation only via the heat pump
■
Dual mode parallel
Demands can be sent to both heat generators (heat pump and external heat
generator) in parallel.
■
Dual mode alternative
Demands can be sent to both heat generators (heat pump and external heat
generator), but they never both run at the same time.
Note
DHW is always heated by the integral instantaneous heating water heater.
Dual mode point Dual mode temperature:
Temperature limit between heat pump-only mode and parallel operation of the
heat pump and external heat generator
Alternative point Alternative mode temperature limit:
Temperature limit between operation with the heat pump and operation with the
external heat generator
Note
DHW is always heated by the integral instantaneous heating water heater.
Control modes Control strategy settings:
■
Constant temperature limits
■
Economical control strategy for minimum running costs
■
Ecological control strategy for minimum CO
2
emissions
Temperature offset, exter-
nal heat generator
Offset for boiler temperature sensor:
For raising the set flow temperature to compensate for a slightly too low flow
temperature from the mixer.
