COOLING OPERATION
How it works:
In cooling mode, your
sophia indoor unit
will absorb heat from the room,
then the
Sophia outdoor unit
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 Free
z
e 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

HEATING OPERATION
How it works:
In heating mode, your
Sophia outdoor unit
will absorb heat from the outdoor
ambient, then the
Sophia indoor unit
will discharge the heat to the room. The
Sophia
heating capacity decreases as the outdoor temperature decreases.
During extreme cold outdoor temperatures, you may need an additional
heating source to supplement the
Sophia
heating output.
Defrost Function:
In heating mode, frost may form on the outdoor coil during humid and low
outdoor temperature conditions. Prolong operation may cause ice to form

heating capacity.
If the
sophia
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 be discontinued and the
Sophia indoor unit
will
and outdoor fans will stop. It is normal to see steam or vapor coming from
the outdoor unit during defrost mode. Defrost mode will terminate 12
minutes after initiation of defrost cycle or when the outdoor coil temperature
is 50°F (10°C) or greater.
