Samsung NH300WHXES Backup Heater Variables for Space Heating, Operating advanced function

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.
