room temperature is decreased. The cooling capacity will increase or decrease according
to outdoor ambient temperature.
F reeze Protection:
If the unit is operating in COOL mode and in low ambient temperature, frost may form
on the heat exchanger. When indoor heat exchanger temperature decreases below zero,
compressor will stop operation to protect the unit.
