When:
Decrease of suction pressure by more than 5.8 PSI
Outdoor temperature below 50˚F, coil temperature below 39˚F
Leaving water temperature is more than 86˚F (to reach confort quickly in cold starts)
Defrost end by suction pressure rise or maximum time
How:
Reverse cycle: under severe condition:
If the defrost is called in a shorter time for 3 times
If the suction pressure is less than 40.6 PSI
