Functions and control
Domestic Air Conditioner
5.1.5 Heating mode: (cooling only have no the mode)
*Temperature control range : 16ć-30ć
*Temperature control precision: r1ć
*Control Character:
When Tr d Ts, compressor, four-ways valve and outdoor fan motor is on, indoor fan motor runs as in cold blast
mode, and 5 of compensation is added after compressor is started.ć
When Tr >Ts+5 , compressor is off, and the indoor fan motor runs as in warm blast mode.ć
When Tr <Ts+5 , compressor, fourć -ways valve and outdoor fan motor is on, and the indoor fan motor 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 d Tr d Ts+2 , the wind speed is medium. ć
When Ts+2 ć d Tr, the wind speed is low.
*Control of air door: setting the position of air door as required.
*Compressor controlThe compressor can’t be controlled by temperature sensor in 2 minutes after start
up and also can’t be started again at least 3 minutes later after shut down. There are 3-minute protection with
power on for the first time (over 3 minutes with power off). The compressor must be started 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 10
seconds earlier than compressor does. After compressor stops runnig, the 4-way valve continues running for
2 minutes and then stops. If changing the unit from heating to cooling, the 4-way valve is shut off 2 minutes
later and compressor is started 3 minutes later.
5.1.5.1 Cold draft prevention:
5.1.5.1.1 Compressor is interrupted during the defrosting operation and continues to run after defrosting
is completed. When the indoor exchanging temperature is below 23 , the indoor fan motor is off. When the ć
indoor exchanging temperature is above 23 , the indoor fan motor is running at weak speed.ć
5.1.5.1.2 If the temperature of coil pipe can’t be above 38 4 minutes later after start up, fan motor is ć
running at the preset wind speed.
5.1.5.1.3 If the temperature of coil pipe is above 38 4 minutes later after start up, fan motor is running ć
at the preset wind speed.
5.1.5.1.4 If coil pipe descends to the temp. lower than 38 from 38 . fan motor is running at the preset ćć
wind speed.
*Warm blast: If the temperature sensor is off. Compressor stops runnig. If the temperature of coil pipe is
above 23 , fan motor enter breeze mode; and if the temperature of coil pipe is below 20 , fan motor stops ć ć
running.
5.1.5.2 High temperature protection and high temperature expiration protection:
5.1.5.2.1 High temperature prevention: When the temp. of coil pipe is above 58ď, the outdoor fan motor
stops.When the temp descends to 53ď, the outdoor fan motor is restarted and fan speed invertage
frequence is more than 45 seconds.
5.1.5.2.2 High temperature expiration prevention:When the temp.of coil pipe is above 72ď,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 65ď, the unit can be started again.
