Description 1. After the power ON/OFF button is pressed once, the relay and triac are turned ON or OFF per the remote control setpoint. – TRIAC is controlled per the fan speed selection. – RELAY is controlled per the operation mode selection. 2. If the power ON/OFF button is pressed once more, the relay and triac are turn off and the unit stops operation. 3. The unit turns on or off according to the temperature set point by sensing the room air temperature through thermistor. 4.
8. TRO UBLE SHO O TING Is the unit display mormal? YES NO NO check the failure code according to the self-diagonostic (note 2) Is the unit display normal? YES Outdoor unit does not run?(note.
