Cooling, dry and fan modes (outdoor logic)
What happens, in order
- Cooling room at or above setpoint starts indoor fan, outdoor fan and compressor; 4-way valve stays off
- Room at or below setpoint minus 2C compressor stops and the outdoor fan stops 30 s later; between the two the unit keeps its previous state
- If the compressor stops on a fault in cooling, the indoor fan and swing carry on as before
- Dry room above setpoint starts compressor and outdoor fan with the indoor fan low; room at or below setpoint minus 2C stops the compressor, outdoor fan 30 s later; protections as in cooling
- Fan mode indoor fan runs at the selected speed (not Turbo); compressor, outdoor fan and 4-way valve stay off
