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 either the outdoor coil temperature sensor reaches
the defrost terminate set point, or 13 minutes, 39 seconds of compressor run time
has elasped with the control in the defrost mode. (See installation instructions for
available terminate temperatures and their specific jumper location)
