Domestic air conditionerWhen Tr Ts, compressor, four-ways valve and outdoor fan motor is on, indoor fan motor runs asin cold blast mode, and 4 of compensation is added after compressor is started.When Tr Ts+5 , compressor is off, and the indoor fan motor runs as in warm blast mode.When Tr , compressor, four-ways valve and outdoor fan motor is on, and the indoor fanmotor runs as in the mode of avoiding cold blast.*Control of indoor fan motor:Manual operation: The wind speed can be set to high, medium, low or automatic as required.Automatic operation: When Tr Ts, the wind speed is high;When Ts Tr Ts+2 , the wind speed is medium.When Ts+2 Tr, the wind speed is low.*Control of air door: setting the position of air door as required.*Compressor control The compressor can’t be controlled by temperature sensor in 2 minutes afterstart up and also can’t be started again at least 3 minutes later after shut down. There are 3-minuteprotection with power on for the first time (over 3 minutes with power off). The compressor must bestarted again 3 minutes later after shut down.*Avoiding electrical shock: outlet air is available 2 seconds later after start up.*Timer on, Timer off and sleep control are available.*Control of 4-way valve: When the unit is started for the first time, the 4-way valve starts runnig 10seconds earlier than compressor does. After compressor stops runnig, the 4-way valve continuesrunning for 2 minutes and then stops. If changing the unit from heating to cooling, the 4-way valve is shutoff 2 minutes later and compressor is started 3 minutes later.7.1.5.1 Cold draft prevetion:7.1.5.1.1 Compressor is interrupted during the defrosting operation and continues to run afterdefrosting is completed. When the indoor exchanging temperature is below 23 , the indoor fan motor isoff. When the indoor exchanging temperature is above 23 , the indoor fan motor is running at weakspeed.7.1.5.1.2 If the temperature of coil pipe can’t be above 38 4 minutes later after start up, fanmotor is running at the preset wind speed.7.1.5.1.3 If the temperature of coil pipe is above 38 4 minutes later after start up, fan motor isrunning at the preset wind speed.7.1.5.1.4 If coil pipe descends to the temp. lower than 38 from 38 . fan motor is running at thepreset wind speed.*Warm blast: If the temperature sensor is off. Compressor stops runnig. If the temperature of coilpipe is above 23 , fan motor enter breeze mode; and if the temperature of coil pipe is below 20 , fanmotor stops running.7.1.5.2 High temperature protection and high temperature expiration protection:7.1.5.2.1 High temperature prevention: When the temp. of coil pipe is above 56 , the outdoorfan motor stops.When the temp descends to 52 , the outdoor fan motor is restarted and fan speedinvertage frequence is more than 45 seconds.7.1.5.2.2 High temperature expiration prevention:When the temp.of coil pipe is above62 ,compressor and outlet air stop running 10 seconds later, and inlet air runs as the temp. sensor is off.When compressor stands by for 3 minute and the temp. of coil pipe is below 50 , the unit can be startedagain.*Current protection and current expiration protection: (Not detecting within 60 seconds after start up)*Overcooling protection One and half a minutes later after compressor starts, if the temperature of15Functions and control
