Cooling in operation according to Remote Control setting.
Time Delay Safety Control (3 minutes)
7 minutes Time Save Control
Anti-Freezing Control
•
If the temperature of the indoor heat exchanger falls
continuously below 2°C for 4 minutes or more, the
compressor turns off to protect the indoor heat exchanger
from freezing. The fan speed setting remains the same.
•
Compressor will restart again when the indoor heat
exchanger temperature rises to 10°C (Recovery).
3 minutes waiting of Time Delay Safety Control is valid for
Cooling Operation.
Compressor Reverse Rotation Protection Control
Anti-Dew Formation Control
7 Operation Details
7.1. Cooling Mode Operation
•
When the compressor is stopped by Remote Control, it restarts after 3 minutes when it is turned ON by Remote Control.
•
When the setting temperature is reached during cooling operation, the compressor stops and it will not start for 3 minutes.
•
The compressor will start automatically if it has stopped for 7 minutes even if the room temperature is between the compressor
ON temperature and OFF temperature.
•
If the compressor is operating continuously for 5 minutes or longer and the temperature difference between intake air and
indoor heat exchanger is 2.5°C or less for 2 minutes, compressor will stop and restart automatically.
(Time Delay Safety Control is valid)
▲
T = Intake air temperature - Indoor heat exchanger temperature
This is to protect reverse rotation of the compressor when there is a instantaneous power failure.
•
Purpose is to prevent dew formation on indoor unit air discharge area.
•
When the following conditions occur for 30 minutes continuously, anti-dew formation is controlled by indoor fan speed shift to
low (Changed to HLo):
−
Indoor intake air temperature is more than 24°C and less than 30°C.
−
Remote Control setting temperature is less than 25°C.
−
Compressor is on.
−
Cooling operation mode.
−
Indoor Fan motor operate at Low fan speed.
•
This control is cancelled immediately when above condition is changed.
