Backup Heater Variables for Space Heating
The FSV #4021 should be set to “1(On)”(Default) to use 2-stage electric backup heater in
hydro unit as an additional heat source.
To compensate the lowered heat pump heating performance under very cold weather
conditions, the FSV #4023 should be set to “1(On)”(Default).
- The threshold temperature to use backup heater for cold weather compensation:
FSV #4024, Default “0˚C”, Range -15 ~ 35˚C
- Above the threshold temperature, the backup heater usage is restricted to save energy
consumption.
The FSV #4022 for backup heater priority should be set to “0(both)”(Default) or “1”(backup)
to use backup heater. If not(booster heater priority), the backup heater can be operated in
case of no booster heater demand.
To use both heaters together at the same time, please check the capacity of the power
circuit breaker of your house before.
External Backup Boiler for Space Heating (Field Option)
The FSV #4031 should be set to “1(Yes)” to use a backup boiler as an additional heat
source. By default option(“0(No)), no installation.
Under the installation of backup boiler in your house, you can freely choose the boiler
priority(FSV #4032, Default “0(Off)”).
To compensate the lowered heat pump heating performance under very cold weather
conditions, the backup boiler will be operating instead of heat pump under the threshold
temperature(FSV #4033, Default “-15˚C”, Range -20 ~ 5˚C).
