COOLING OPERATION
How it works:
In cooling mode, your indoor evaporator will absorb heat from the room,
then the outdoor
condenser will discharge the heat to the outdoors. The
sophia cooling capacity decreases as the outdoor temperature increases.
This causes the
ali ce
to work harder and longer to hold the selected room
temperature.
Indoor Coil Freeze Protection:
Frost may form on the indoor coil during cooling operations when the
outdoor temperature below 50°F (10°C). Prolong operation may cause ice
indoor evaporator’s
microcomputer detects ice on the indoor coil it will stop the compressor to
defrost the coil and protect the unit.
HEATING OPERATION
How it works:
In heating mode, your outdoor condenser will absorb ambient heat from
outdoors, then the indoor evaporator will discharge the heat to the room. The
heating capacity decreases as the outdoor temperature decreases.
During extreme cold outdoor temperatures, you may need an additional
heating source to supplement the heating output.
Defrost Function:
In heating mode, frost may form on the outdoor coil during humid and low
outdoor temperature conditions. Prolonged operation may cause ice to form
on the outdoor coil and block airflow. This will reduce the heating capacity.
If the microcomputer detects ice on the outdoor coil, it will switch automatically
to defrost mode to melt the ice and clear the coil. During defrost mode,
heating will pause and the indoor evaporator will flash the Defrost indicator.
The compressor will continue to run while the indoor and outdoor fans will stop.
It is normal to see steam or vapor coming from the outdoor unit during defrost.
Defrost mode will terminate 12 minutes after it begins the cycle or when the
outdoor coil temperature is 50°F (10°C) or greater.
