Booster Heater Variables for Controlling DHW Tank
•
The FSV #3031 should be set to “1(On)” (Default) to use booster heater as an additional heat source for
DHW tank.
•
Booster heater startup delay timer : In case of DHW request, this timer will delay the operation of
booster heater compared to heat pump.
– FSV #3032 (Default 20 min., Range 20 ~ 95 min.), In “Power” DHW mode, the delay timer will be
neglected, and the booster starts immediately.
– In “Economic” DHW mode, the DHW heating will be conducted only with heat pump.
– #3032 should be smaller than the maximum H/P time (#3025). If the delay time is set too high, it
might take very long time for DHW heating.
•
Temperature difference determining the booster heater OFF temperature (T_BH OFF = Tu + #3033) :
FSV #3033, Default 0˚C, Range : 0 ~ 4˚C.
•
Temperature difference determining the booster heater ON temperature (T_BH ON = T_BH OFF - 2)
NOTE
•
The FSV #4022 for booster heater priority should be set to “0 (both)” (Default) or “2” (booster)
to use booster heater.
•
If not(backup heater priority), the booster heater can be operated in case of no backup heater
demand.
