8-3. Freeze Prevention (Cooling and Dry)
This function prevents freezing of the indoor heat exchange coil.
When the temperature of the indoor heat exchange coil falls below 2 °C for 2 minutes, the control circuit stops the outdoor fan and compressor (The compressor stops 3 seconds after the outdoor fan stopped). During this period, Indoor fan operates in LL. The outdoor fan does not start again until the temperature rises above 6°C. (The compressor starts 2 seconds after the outdoor fan started.)
