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.
