Part 4 Functions and Control
3.6 Automatic Restart
Purpose
The purpose of the auto-restart function is to automatically resume the same operating mode as
when the unit was operating when the power supply is restored after a power failure.
Do not use the "Automatic Restart" function to daily start/stop the unit.
Precautions when turning OFF power
When you have to turn OFF the power supply in order to carry out maintenance, make sure
to turn the remote control's ON/OFF switch OFF firstly.
If you turn OFF the power supply while the remote control's ON/OFF switch is still ON, the
"automatic restart function" automatically starts the indoor fan immediately and the outdoor
fan starts automatically 3 minutes after the power supply is restarted.
Do not start/stop the unit by disconnecting the power supply. Stop the unit by stop
commando from the remote controller or optional controller before disconnecting the power
supply. Be sure that the compressor and the outdoor unit fans are stopped before
disconnecting the power supply so the "Refrigerant Recovery function" has been finished
correctly.
When restarting the unit after the power was disconnected for a longer period leave the unit
OFF with the power supply connected for about half an hour (See "Preheating Control").
3.7 Monitoring Control
When the indoor fan is turned off while the thermostat for cooling or drying is off, even if the
room temperature recovers afterwards and becomes the one that turns the thermostat on, the
thermistor cannot detect room temperature because the suction air thermistor is installed inside
the indoor unit.
In order to prevent such a condition, this monitoring control has the function of detecting room
temperature by operating the fan at certain intervals when the fan is turned off while the
thermostat is off.
