SYSTEM OPERATION
COOLING OPERATION
How it works:
In cooling mode, your
neo
indoor unit will absorb heat from the room, then the
neo
outdoor unit will discharge the heat to the outdoors. The
neo
cooling capacity
decreases as the outdoor temperature increases. This causes the
neo
to work harder
and longer to hold the selected room temperature. Your
neo
unit will operate in
cooling down to 41°F (5°C)
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 to form on the
indoor coil and block airflow. If the
neo
indoor unit 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
neo
outdoor unit will absorb heat from the outdoor ambient,
then the
neo
indoor unit will discharge the heat to the room. The
neo
heating
capacity decreases as the outdoor temperature decreases. Your
neo
unit will heat
down to 5°F (-15°C).
During extreme cold outdoor temperatures, you may need an additional heating source
to supplement the
neo
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 on the outdoor coil
and block airflow. This will reduce the
neo
’
s heating capacity.
If the
neo
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
neo
indoor unit will flash the Defrost indicator. The compressor
will continue to run while indoor 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.
