[Time variation control of Heat pump and booster heater of DHW]
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.
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/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_BH OFF = Tu + #3033) :
Temperature difference determining the booster heater ON temperature (T_BH ON = T_BH OFF - 2)
