• Temperature difference determining the heat pump OFF temperature :
FSV #3022, Default 2˚C, Range : 2 ~ 10˚C.
• Temperature difference determining the heat pump ON temperature :
FSV #3023, Default 5˚C, Range : 1 ~ 20˚C.
• DHW heating mode timer : I f there is simultaneous requests of space heating/cooling and
- F SV #3024(minimum DHW operating time, Default 5 min., Range 0 ~ 20 min.),
#3025(maximum DHW time, Default 30 min., Range 5 ~ 95 min.), #3026(time interval
between two consecutive DHW mode operations, Default 3 hour, Range 0 ~ 10 hour)
