Note: Subcooling information is valid only while the unit is operating at
100% capacity or 100% of compressor speed in CHARGE MODE.
Compressor speed is displayed under STATUS menu in the thermostat.
NOTE: Not more than 3/8 lb. (6 oz.) of refrigerant be added
to the system at a time to achieve the target subcooling. It
is recommended adding 1 oz. refrigerant each time, then
wait 10 minutes to stabilize the system.

heat pump WIth outdoor temperature
lockoutS
It is recommended to set the outdoor temperature lockouts
during the initial thermostat set up. Compressor lockout
temperature will enable the compressor to be turned off and
switch heating source from refrigeration to auxiliary/secondary
heating under low outdoor ambient conditions.
In case of 30 ft. or longer line set application, refrigerant may
be accumulated inside line set pipe. Select 15°F or higher
compressor (heat pump) lockout temperature to set heat
pump lockout.
Backup heat lockout temperature will enable auxiliary/sec-
ondary heating to be turned on when outdoor temperature
is much higher than indoor temperature, compressor might
stop operating under this circumstance.
