mode by the difference between current set temperature and the room temperature, and then operate

in the determined mode. In the following selection condition, Tr indicate room temperatureˈTs indicate

set temperature.

In First enter auto mode, select operating mode as following condition:

Tr=Ts -3 select cool modeć

Tr˘Ts-3 select heat modeć

When system enter the auto mode, the operation mode will switch between cool and heat according to

change of the indoor temperature: if the unit operating in the cool mode, when system temperature

arrive at stop value of compressor, the compressor to off and stop continuously for 15 minutes, and

then to detect the room temperature, at this point, if Tr ˘Ts-3 , then the system enter the heat mode,ć

otherwise it will operate continuously in the cool mode; if the unit operating in the heat mode, when
