This function prevents freezing of the indoor heat exchange coil.
When the compressor has been running for 10 minutes or more and the temperature of the indoor heat
exchange coil falls below 30°F, the control circuit stops the compressor for at least 6 minutes. The compressor
does not start again until the temperature rises above 46°F or 6 minutes has elapsed.

This function prevents overheating of the indoor heat exchange coil.
When the temperature of the indoor heat exchange coil rises above 139°F, and if the indoor fan is L (low
speed), then the fan speed changes from L (low speed) to M (medium speed).
When the temperature of the indoor heat exchange coil rises above 141°F, the outdoor fan stops.
