Domestic Air Conditioner
Functions and Control
5.1.5 Heating mode:
(cooling only have no the mode)
*Temperature control range : 16 —30
*Temperature control precision: 1
*Control Character:
When Tr Ts, compressor, four-ways valve and outdoor fan motor is on, indoor fan motor runs as
in 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<Ts+5 , compressor, four-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 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 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 prevetion:
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 indoor exchanging temperature is above 23 , the indoor fan motor is running at weak
speed.
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 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 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 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 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 56 , the outdoor
fan motor stops.When the temp descends to 52 , 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
62 ,compressor and outlet air stop running 10 seconds later, and inlet air runs as the temp. sensor is off.
