Verify the proper operation of the system by running the In staller Test feature through the thermostat interface. Refer to the iComfort Wi-Fi® Installer System Setup Guide.
COMPRESSOR SHORT CYCLING DELAY
The outdoor control protects the compressor from:
– Short cycling (five minutes) during initial power-up.
– Interruption in power to the unit.
– Pressure or sensor trips.
– Delay after demand is removed.
The delay is set by default for 300 seconds (five minutes) but can be changed through the thermostat interface.
Available settings are 60, 120, 180, 240 and 300 seconds.
CRANKCASE HEATER (HR1)
Compressors in all units are equipped with a 40-watt belly-band-type crankcase heater. HR1 prevents liquid from accumulating in the compressor. HR1 is controlled by the crankcase heater thermostat.
CRANKCASE HEATER THERMOSTAT (S40)
Thermostat S40 controls the crankcase heater in all units.
S40 is located on the liquid line. When liquid line temperature drops below 50°F, thermostat S40 closes, energizing HR1. The thermostat opens, de-energizing HR1, once liquid line temperature reaches 70°F.
