Booster Heater Variables for Controlling DHW Tank (FSV#3031~3033)
• 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.
–
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) :
• 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)" 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 model "AE200DN****" does not have the booster heater but is alternatively controlled by the backup
heater. If you want an alternative control, FSV#3031/FSV#6051 should be set to 1.
