When the unit operates at low ambient temperature, frost may appear on the Evaporator. When the indoor coil
temperature is lower than -1 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.
