hour.After the temperature has increased by 3°C, the unit will keep this temperature. When the unit has operated for 7 hours, the
temperature will decrease by 1°C and then the unit will operate at this temperature all the time;
②
When the initial temperature is set as 24~27°C, after starting up the sleep function, the temperature will increase by1°C every one
hour.After the temperature has increased by 2°C, the unit will keep this temperature. When the unit has operated for 7 hours, the
temperature will decrease by 1°C and then the unit will operate at this temperature all the time;
③

hour.After the temperature is decreased by 2°C, the unit will operate at this temperature;
④
When the initial temperature is set as 28~30°C, after starting up the sleep function, the temperature will decrease by1°C every one
hour.
After the temperature is decreased by 3°C, the unit will operate at this temperature;
General timer and clock timer functions are compatible by equipping different functions of remote controller.
