If brine is adopted as an outdoor side heating medium, AR11 needs to be changed
according to brine freezing point. AR11 parameter set value should be 10°C
higher than the brine freezing point. If the brine freezing point is -15°C, then
AR11 could be set to -5°C.
At this condition, AR08 set value could be 2°C lower than AR11. If AR11= -5°C,
AR08 could be set to -7°C.
