8. Operation Details
8.1. Cooling Mode Operation
Cooling inoperation according toRemote Control setting.
Time DelaySafetyControl (3 minutes)
-When the compressor isstopped byPower Switch or Remote
Control, itrestarts after 3minutes when the Power Switch or
Remote Control isturned ON.
18

-When the setting temperature isreached during cooling operation,
the compressor stops and itwill not start for 3minutes.
7 minutes Time SavedControl
-The compressor will start automaticallyifithas stopped for 7
minutes even ifthe room temperature isbetween the compressor
ONtemperature and OFF temperature.
Starting Current Control
-When the compressor, outdoor fan motor &indoor fan motor are
simultaneouslystarted, the indoor fan motor will operate 1.6
second later.
Anti-Freezing Control
-Ifthe temperature of the indoor heat exchanger fallscontinuously
below 2°Cfor 4minutes or more, the compressor turns off to
protect the indoor heat exchanger from freezing. The fan speed
setting remains the same.
-Compressor will restart againwhen the indoor heat exchanger
temperature rises to 10°C(Recovery).
3minutes waiting of Time DelaySafetyControl is validfor
Cooling Operation.
CompressorReverse Rotation Protection Control
19

-Ifthe compressor isoperating continuouslyfor 5minutes or longer
and the temperature difference between intake airand indoor heat
exchanger is2.5°Cor less for 2minutes, compressor will stop and
restart automatically. / (Time DelaySafetyControl isvalid)
T= Intake airtemperature -Indoor heat exchanger temperature /
Thisisto protect reverse rotation of the compressor when there is
ainstantaneous power failure.
CompressorProtection Control
-After the compressor starts for 50 seconds but the outdoor fan
motor isstill OFF, the compressor will stop and restart
automatically. (Time DelaySafetyControl isvalid).
-Ifthe above phenomenon isrepeated for 3times, the compressor
will stops.
-The above phenomenon isreset when there isachange to heating
mode or stopped byRemote Control Switch.
Automatic FanSpeedMode
WhenAutomatic FanSpeedis selectedat Remote Control during cooling operation.
-Fan speed rotates inthe range of Hi to Me.
-Deodorizing Control.
