● When the temperature of coil pipe of the indoor units is more than or equal to 7℃ and the compressor has shutdown for more than three minutes, the compressor and outdoor blower fan start to run and the indoor blower fan is running at set speed. ● When the temperature of coil pipe of the indoor units is equal to or less than －10℃ for three minutes in the compressor has continuous run for three minutes, the compressor, indoor and outdoor blower fans and swinging wind shut down.
Tr r o s s e r p m o c n a f r re o w o o dl b Heating (only applicable to heat pump units) ● Start up the compressor: when the room temperature is less than Ts-1℃, 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: ① start up the compressor and indoor blower fan ② none defrost ③ TP1< 49℃ ④Tr ≤20℃.
closed and two minutes later, the change valve is closed. The indoor blower fan is running at the set speed. Restart up six minutes later; if the above situations appear again within ten minutes, all the outputs are shut down through the electric control board and display failure.
Defrost (only applicable to the heating mode) 1. the intelligent defrost In the heating mode, the electric control board checks and compares the temperature of indoor room and indoor coil pipe after the compressor works for a while; judge whether the outdoor heat exchanger part is frosted or not according to conditions such as the change of indoor coil pipe temperature; if it is judged as frosted, it automatically enters defrosting process.

In the ventilation mode .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. Automatic mode ● Conditions for entering the automatic running mode are: After power-up for the first time, start up and select the automatic operating mode of remote or press emergency key, the working mode depends on Tr and if the working mode had set , it doesn’t change by Tr and the default set temperature is 25 ℃.
the normal temperature 25℃), when it is state abnormal the sensor should be replaced. 2、Check whether there is short circuit or open circuit in the wire of the sensor, and whether the plug is connected well, whether there is welding off or rosin joint on the electric control board, if there is any, it should be repaired. 3、When the 1 and 2 are both normal, then the components or integrated circuit is damaged, the electric control board should be replaced.
display at SEC off state at off signal normal. 2、Check whether the signal outputting from state the integrated chip of the electric control board is normal, the electric control board should be replaced when the signal is abnormal. 1、Check whether the winding resistance and operation current of the compressor are normal 2、Check whether the high and low pressure is normal when the unit is running.
8. TROUBLE SHOOTING Indoor Tr sensor error Is CN (Tr sensor connector) connected properly? NO Connect CN properly. YES Is Tr sensor resistance value (5KO at 25? ) normal? NO Replace TA sensor. YES Indoor P. C. board is defective. Replace P. C. board. Indoor TP1 sensor error Is CN (TP1 sensor connector) connected properly? NO Connect CN properly. YES Is TP1 sensor resistance value (5KO at 25? ) normal? NO Replace TC sensor. YES Indoor P. C. board is defective. 第 55 页 共 59 页 Replace P. C.
Only indoor fan motor does not operate. (1) Is it possible to detect the power supply voltage (200-240V) between L and N on the terminal block? (2) Does the indoor fan motor operate in cooling operation? Turn off power supply once, and turn it on again. Does compressor continue to operate? YES NO Is it possible to detect AC 220V between pin(high/middle/low) and pin(common) of motor connector . Start to operate indoor unit in cooling operation at airflow level “LOW”,wait three minutes..
Compressor does not operate. Turn on power supply. Does OPERATION indication indicate? (1) Is the room temperature higher than the preset temperature in cooling operation? (2) Is the crossover cable connected properly? NO Check power supply. YES Does compressor delay three minutes by temperature changes or others? NO Is resistance value of room sensor (Tr) and heat exchanger sensor (TP1) normal? NO Room sensor or heat exchanger sensor is defective.
Trouble shooting NO Trouble Is the unit display normal? YES Check power supply mains or interconnection wires YES Does outdoor unit run? YES NO Is the power appliedto the unit? NO Does the compressor run normally? Is the power normal? check the voltage between L&Nof terminal block Check the compressor ,wires and it’s capacitor.
Indoor unit and outdoor unit don’t operate Indoor and outdoor unit don’t operate Does the electric switch cut off after a few nimutes? Does the electric switch cut off? YES Is the power supply no problem? YES NO Reconnect the wires.
