→ ADDITIONAL HEATING
Freezing protection only
The electric heater will be switched on only when heating water temperature falls
below +5 °C. The freezing protection function monitors the temperature in the
condenser, buffer tank, and the heating circuits. Once the temperature exceeds
+10 °C, the electric heater will be switched off. In freezing protection, space heating
takes precedence over heating domestic hot water.
● If this option is selected, the electric heater won’t be switched on during a
fault, unless the temperature falls below the Freezing protection limit.
Backup use only
The electric heater will be switched on, if:
1. The outdoor temperature is below 5 °C (freezing protection).
2. An alarm prevents the compressor from starting (backup operation).
In backup use, space heating takes precedence over heating domestic hot water.
Select this option, if the fuse for the heat pump power supply is not rated for running
the compressor and the electric heater in parallel.

With compressor (parallel operation)
The electric heater will be switched on, if:
1. The outdoor temperature is below 5 °C (freezing protection).
2. An alarm prevents the compressor from starting (backup operation).
3. The target temperature for flow water from the heat pump has not been
reached, and the start delay for the electric heater has elapsed.
Select this option, if the fuse for the heat pump power supply is rated for running the
compressor and the electric heater in parallel.
NOMINAL OUTPUT
OF POWER
STAGES
The rated output for the power stages in the condenser circuit’s in-line heater.
There can be three power stages. The value is used for assessing electrical power
consumption and in functions that restrict the heat pump’s electrical current.
