8. System configuration
NOTE
• The FSV #4022 for booster heater priority should be set to "0" (both) 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.

• 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/Forced" 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 bsh OFF = T s + #3033) : FSV #3033,
Default 0 ˚C, Range : 0 ~ 4 ˚C.
• Temperature difference determining the booster heater ON temperature ( T bsh ON = T bsh OFF - 2)
