-When the compressor isstopped byPower Switch, Remote
Control or there isapower failure, itrestarts after 3minutes when
the Power Switch, Remote Control isturned ONor the power
supplyisresumed.
-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 isbelow the compressor ON
temperature.
Anti-Freezing Control
-Ifthe temperature of the indoor heat exchanger fallscontinuously
below 2°Cfor 4minutes, the compressor turns off to protect the
indoor heat exchanger from freezing. The fan speed setting
remains the same. /
-Compressor recommences when the indoor heat exchanger
temperature rises to 10°C(Recovery).
3minutes waiting of Time DelaySafetyControl is valid
for Cooling Operation.
