Freeze Prevention for Indoor Coil (Cooling)
(Cooling Mode)
During the cooling operation, if the temperature of the indoor coil falls below 34°F for a period of
approximately 5 minutes, the compressor will shut off. This will prevent the indoor coil from freezing.
The compressor will start running again when the coil temperature reaches 50°F or above.
The safety restarting function will prevent the compressor restarting if the minimum 3-minute shutdown
time period has not elapsed. The indoor fan motor will continuously operate during this coil freezing
prevention mode.
The indoor coil freeze prevention function is also available in the Class 2 mode.
