Outdoor Side Anti-Freezing Setting
Ground water with immediate heat exchanger system
AR11 (outdoor side low outlet water temperature protection), factory default setting is 5
℃
.
AR08 (low evaporator temperature protection), factory default setting is -2
℃
.
Ground loop system
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.
