Compressor Reverse Rotation Protection Control

7.3. Heating Mode Operation

  • 

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.

  • 

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.

(a) Outdoor Fan Control

  • 

A12CT

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

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

  • 

A18CT, A24CT

If the temperature of the Outdoor Heat Exchanger less than -3°C, Outdoor Fan is ON. The Outdoor Fan stop, when Outdoor
Heat Exchanger temperature is T

b

or more according to Outdoor Air Temperature region as table below:

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

During starting of Heating mode and after deice, Outdoor Fan ON for 90 sec.

(b) Compressor high pressure protection

  • 

If the indoor heat exchanger becomes 65°C (A12CTP); 68°C (A18CTP & A24CTP) or more, the compressor will stop and
restart automatically.

(Time Delay Safety Control - 4 minutes waiting).

  • 

If the compressor is operating continuously for 5 minutes or longer and temperature difference between intake air and indoor
heat exchanger is 5°C 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.

This is to protect reverse rotation of the compressor when there is a instantaneous power failure.
