Operating advanced function _39ENGLISHBooster Heater Variables for Controlling DHW Tank• The FSV #3031 should be set to “1(On)”(Default) to use booster heater as an additional heatsource for DHW tank.• Booster heater startup delay timer : In case of DHW request, this timer will delay theoperation of booster heater compared to heat pump.- FSV #3032(Default 20 min., Range 20 ~ 95 min.), In “Power” DHW mode, the delay timerwill 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 toohigh, 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_BHOFF - 2)• DHW compensation temperature in case of space heating/cooling priority : FSV #3034 willbe 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.If not(backup heater priority), the booster heater can be operated in case of no backupheater 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.Urgent DHW by User’s Input (Hot Key of Wired Remote Controller)• Urgent DHW mode can be activated by changing setting value from the default setting(#3011,”0”(No)).• Urgent DHW mode shall be working depending on Timer setting(#3051, #3052).RC120MHXGA_IB_E_34412A(1).indd 39 2012-02-08 오후 2:35:52
