Frost Prevention of Indoor Unit
When the unit operates at low ambient temperature, frost may appear on the Ev aporator. When the indoor coil
temperature is lower than 0°C at the end of 10 minutes of continuous compressor operation from the start, the
microcomputer of the unit stops the compressor to protect the unit from the frost. The control procedure for
indoor coil freeze protection.
1) The compressor and outdoor fan turn off.
2) Indoor fan operates according to user set speed.
3) The normal operation returns when the indoor coil
temperature is higher than 7°C or equal to 7°C.

Power Supply(1)
DESCRIPTION
DC Po wer Supply in circuit needs +12V and +5V. +12V is used for Compressor Driving Relay, T riac Driving
Photo Triac, Buzzer Driving Swing, Sweep Motor. AC voltage of secondary Po wer Transformer is rectified by
Bridge Diode, and it is filtering by Main Condensor CE1.
Filtered DC voltage is about +18V, is regulated +12V DC by Regulator IC7812.
And it is regulated +5V DC by Regulator IC7805.
V AR is serge filter and CC1, CC2, CC3 is Noise filter .
