8.2.17
Symptom: The inside of an outdoor unit is
warm even when the unit has stopped
This is because the crankcase heater is warming the compressor so
that the compressor can start smoothly.
8.2.18
Symptom: Hot air can be felt when the
indoor unit is stopped
Several different indoor units are being run on the same system.
When another unit is running, some refrigerant will still flow through
the unit.
