Function
The points of thermostat ON or OFF are determined according to the suction air temperature at
the startup of unit operation.
The set temperature and flow rate are not displayed on remote control.

2. Operation condition
Auto-restart
Function
If there is a power cut when the unit is operating, it will automatically resume the same operating
mode when the power is restored.
Caution
When performing maintenance and the power supply is to be shut off, be sure to turn the remote
control’s ON/OFF switch OFF first.
Shutting the power supply switch off while the ON/OFF switch is still ON is dangerous because
the “power failure automatic reset function” will cause the indoor fan to start turning
immediately, or the outdoor unit fan to automatically start turning three minutes after the power
supply is turned back on.
