11.5.4. Freeze Prevention Control
• After compressor starts operation for 4 minutes, the outdoor unit will stop its operation if indoor pipe temperature falls below 2ºC
for 6 minutes.
• After 3 minutes stops, compressor restarts operation if indoor pipe temperature is 3ºC or more.
• This phenomenon is to protect the indoor heat exchanger from freezing and to prevent higher volume of refrigerant in liquid from
returning to the compressor.
