8.3. Heating Mode Operation

Heating in operation according to Remote Control setting.

Time Delay Safety Control

When the compressor is stopped by Remote Control, it restarts after 3 minutes when the Remote Control is turned ON.

•

When the setting temperature is reached during heating operation, the compressor stops and it will not start for 4 minutes.

•

30 minutes Time Save Control

The compressor will start automatically if it has stopped for 30 minutes even if the room temperature is between the compressor

•

ON temperature and OFF temperature.

Overload Protection Control

(a) Outdoor Fan Control

If the temperature of the indoor heat exchanger rises to 51°C (123.8°F), Outdoor Fan stops.

•

The Outdoor Fan restarts when the indoor heat exchanger temperature falls to 49°C (120.2°F).

(b) Compressor high pressure protection

If the indoor heat exchanger becomes 65°C (149°F) or more, the compressor will stop and restart automatically.

•

(Time Delay Safety Control - 4 minutes waiting).

Compressor Reverse Rotation Protection Control

If the compressor is operating continuously for 5 minutes or longer and temperature difference between intake air and indoor

•

heat exchanger is 5°C (41°F) or less for 2 minutes, compressor will stop and restart automatically. (Time Delay Safety Control is valid).

▲

T = Indoor heat exchanger temperature - intake air temperature.
