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)
• DHW compensation temperature in case of space heating/cooling priority : FSV #3034 will be explained in next page.
• The FSV #4022 for booster heater priority should be set to "0(both)"(Default) or "2"(booster) to use booster
heater.
NOTE
• If not(backup heater priority), the booster heater can be operated in case of no backup heater demand.
Disinfection Function
• The FSV #3041 should be set to "1(On)"(Default) to use disinfection function.
- Scheduling : Day(#3042, Default "Friday"), starting time(#3043, Default "23:00"), target tank temp. (#3044, Default
"70˚C"), duration(#3045, Default 10 min.)
• Disinfection function can be performed only with Samsung's DHW tank installation.
NOTE
Forced DHW by User's Input
• Forced DHW mode can be activated by changing setting value from the default setting (#3011, " 0"(No)).
• Forced DHW mode shall be working depending on Timer setting(#3051, #3052).
Additional Solar Panel Installation for DHW with Heat Pump (Field Option)
• Solar panel and heat pump are able to operate simultaneously by default setting value. (FSV #3061, "1")
• When using DHW thermostat, set the FSV #3061, "2".
• Zone #1 and #2 valve always keep open except DHW mode in "ON" when the power is "ON" unless changing the FSV #3071.
Default: Room direction valves are open and DHW valve is closed.
• Zone #1 and #2 can be open separately or simultaneously but all three zone valves can not be open or closed at the same
time.
• There is one minute delay of 2-way valve closing whereas no delay of valve opening.
• Individual zone control is only available with external thermostat.
