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.
