When power on for the first time, it is allowed to start up the compressor immediately; in order to protect the compressor, it is required to stop compressor immediately such as transforming mode, heating mode overheat protection and shutdown after starting up the compressor; furthermore, it is advisable to stop the compressor according to practical situations after it has run at least for three minutes. In general, the electric control board will not start up the compressor within three minutes at least after shutting down the compressor. In general, start up the compressor and the outdoor blower fan in the heating mode. The working mode of four-way valve is to open the four-way valve when starting up the compressor. In the course of defrost, the outdoor blower fan and the four-way valve are closed when the compressor starts up. In the course of heating, the compressor is closed without power breakdown or the mode is transformed and two minutes later, the four-way valve is closed.

46 In the heating mode, the indoor flower fan can be set as high/ medium/ low /automatic running mode by remote control. however, the anti cool air function is prior. In the heating mode, the anti cool air control function is to control shutdown of the indoor blower fan, lower (low speed )wind mode, setting the wind speed by detecting the temperature of coil pipe of evaporator so as to attain the purpose of preventing cold air from blowing. When the compressor starts up, the specific situations are shown in the following figure. When the compressor is closed and the temperature of coil pipe of indoor evaporator decreases and is less than 30, the indoor blower fan is closed. When the compressor is turned on and the temperature of coil pipe of indoor evaporator decreases and is less than 20, the indoor blower fan is closed. The operating lamp is light for 0.5s and close for 0.5s to indicate the anti cool air. Start up the compressor: when the room temperature is less than Ts-(Ts is the set temperature), compressor start-up Shut down the compressor: when the room temperature is more than or equal to the set temperature Ts+3, compressor shutdown The electric heating start-up in the heating mode shall meet the following conditions: start up the compressor and indoor blower fan room temperature 20 the temperature of indoor coil pipe < 49 non defrosting mode For the waste heat emission function in the heating mode, in principle, the indoor blower fan shall be on for thirty seconds after the electric heating is closed.

48 6.4 Overheat protection of evaporator (only applicable to the heating mode) This function is to prevent overheat of indoor evaporator. When the temperature of coil pipe of indoor units rises to 65, the compressor and outdoor blower fan are closed and two minutes later, the change valve is closed. The indoor blower fan is running at the set speed. When the temperature of indoor coil pipe is less than or equal to 52, it is allowed to reenter the heating mode. When the temperature of coil pipe of indoor units is more than or equal to 56, the outdoor blower fan shuts down and it enters the overload protection; when the temperature of coil pipe of indoor units is less than or equal to 52, the outdoor blower fan starts up and it exit the overload protection. 65 ãc Temperature of coil pipe of 56 ãc indoor evaporate 52 ãc Compressor Start-up Shutdown Start-up Outdoor blower fan Start-up Shutdown Start-up Indoor blower fan Set wind speed 6.5 Defrosting (only applicable to the heating mode, the intelligent defrosting is adopted) In the heating mode, the air conditioner defrosting by outdoor electric board, defrost start-up in the heating mode shall meet the following conditions: the compressor running time over thirty minutes and it continuous running over three minutes and outdoor unit coil pipe sensor temperature less than or equal 5 degree over one minutes.2 the compressor running time over forty minutes and it continuous running over three minutes and outdoor unit coil pipe sensor temperature less than or equal 5 degree over one minutes. the defrosting time is automatically determined to exit the defrosting and re-enter the heating mode to run. The defrosting scheme is as follows. Sequence chart in defrosting mode

49 Shutdown 6.6 Dehumidification Dehumidification running is to eliminate the water vapor in the air by using the cool circulating capacity, but the dehumidification will not decrease the indoor temperature in great deal. The air conditioner automatically repeats on and off circulation according the room temperature, which is shown in the following figure.. The dehumidify procedure is run mode A or mode B. Then repeat the procedure. * mode A of dehumidification External blower fan of compressor: Intermittent running (run 5 minutes stop 3 minutes.) FMI (indoor fan): Run at low speed. ** mode A of dehumidification External blower fan of compressor: Intermittent running (run 3 minutes stop 5 minutes.) FMI (indoor fan): Run at low speed Note In the dehumidification mode, the indoor fan is running at the set speed.

50 6.7 Ventilation working mode (only applicable to single cold machine) In the ventilation mode, the set temperature range is 6~32. When ventilating, the compressor, outdoor blower fan, four-way valve and electric heating are all closed and the indoor blower fan is running at the set speed. 6.8 Automatic mode When the automatic mode is selected, the electric control board calculates the difference value between the set temperature and room temperature, and then it is automatically switched into the cooling, heating and dehumidification modes to keep the expected temperature. (Note: Tr represents the indoor room temperature and Ts represents the set temperature, the single cold machine changes from the heating mode to the ventilation mode.) Room temperature T R <2 2 T R 26 T R >26 State heating Dehumidification cooling 6.9 Emergency key function There is a forcible execution key on the panel of indoor units and the air conditioner can enter the auto mode by pressing the key when the remote controller is out of work or missing.
