8.3 Indoor fan unit will be high fan before the unit is set for sleeping state. After it is set for sleeping state, fan speed indoors will change into middle fan speed. If indoor fan unit is middle fan speed before it is set for sleeping state, fan speed indoors will change into low fan after it is set for sleeping state. If indoor unit is low fan before it is set for sleeping state, fan speed indoors will keep the same.

. Automatic operation

The automatic operation is divided into automation and full automation by use the variant selection mode.

9.1 Automation operating mode:

Automation operating is on, MCU will select corresponding operation mode based on the room temperature to preserve the set temperature (set temperature is 23 in the heat mode; it is 26 in the cool mode).

For the first power on, if the indoor temperature T=23 the system will operate in the heat mode, T>23 operating in the cool mode.

The system will perform the heat program in the heat mode (set temperature is 23 ), when system temperature arrive at stop value of compressor, the compressor to off and waiting for 3 minutes; after the compressor stop continuance for 15 minutes, if the system detected the ventilation temperature is more than 23 , it will enter cool mode, or else it will continuously operate in the heat mode.

When enter the cool mode and the system operating in cool mode (set temperature 26 ), the compensation temperature contrast will be canceled automatically, when it arrive at the stop temperature of the compressor, the compressor to off and wait for 3 minutes; after the compressor stop continuously for 15 minutes, the system detected the ventilation temperature T=23 , then it will enter heat mode and automatically add the compensation temperature. or else it will continuously operate in the cool mode.

When the system switch from other mode to auto mode, if the operation status change (i.e. first determine and then operation), it will stop for 3 minutes and then determine temperature based on the indoor ventilation temperature.

9.2 Full-automation operation

After system is on and the operation mode will switches to auto mode, the system determine operating 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 temperature Ts indicate set temperature.

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

Tr=Ts-3	select cool mode
Tr Ts-3	select heat mode

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

This mode has timer and sleep function, if the system enter the cool mode, then enter the cool+ sleep mode, if enter the heat mode then enter heat + sleep mode.

Select swing or sticking on one position for the fan blade, and fan speed including: low, middle, high and auto fan, you can select any one of them without control.

. Running-in
