7.3 Timer ON/OFF

The executing order is based on the direction from the board.

. Sleep operating

8.1 During cool/ dry operation, the fixed temperature will rise by 1 after it operates for 1 hour. After another hour the temperature will rise by another 1 . After 6 hours, the unit is off.

8.2During heat-making operation, the fixed temperature will rise by 2

hours the temperature will rise by 2 . The temperature will rise by 1 3 hours, the unit is off.

after 1 hour. After another 2 after three hours. After the last

8.3Indoor 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.
