ARD OPERA
TION:
Heat Pump operates in heating mode until the combination of outdoor ambient
and outdoor coil temperatures initiate a defrost cycle. The outdoor coil
temperature must be at or below 32˚F before the defrost cycle begins.
There must be a minimum of 20 minutes between defrost cycle
s.
After this
time, temperature conditions must call for defrost continuously for 4 1/2
minutes before a defrost cycle is initiated.
The defrost cycle ends when the outdoor temperature reaches 32˚F or the
defrost terminate time of 13 minutes 39 seconds is reached.
