The above protection will go on until Td ≤85 , ℃ and it stops working more than 3 min, then the
compressor will resume normal operation;
When the compressor restart again, if Td reaches more than 110 again within 15 min, the ℃

5、The malfunction protection of indoor fan-motor
If there is no signal after the indoor fan-motor starts working for 10 s, the indo
stop for 30 s. And this will test for three times consec
feedback signal (such as the fan is blocked or damaged, the wiring is disconnected , etc.),
then the digital tube will display the corresponding fault code, furthermore the complete
machine will stop working and can not be activated.
6、The malfunction protection of the sensor
When the indoor and outdoor temperature sensor has

resume to work until the fault code vanishes.
7、Protection of IPDU module
When IPDU breaks down any of the following:
vibration from the position, speed
detection of loop , abnormal current sensor, locking of the compressor, damage of the
compressor, when the Case thermo moves, the compressor stops operating, and the outdo
unit will display the fault code while the indoor unit will show l the total fault code, and th
compressor will re-start again after 3 min. If such failures happen consecutively for two times
within 4 min, there will be permanent shutdown and the power must be cut off if you want t

electricity must be cut
We judge from system failures by this condition only within 20 min after we turn-on the
machine, 20 min later we no longer judge by this condition. If rem
switch is turned off or the electricity is cut off suddenly ,we re-judge system failure afte

There will be small 100 Hz AC voltage when indoor AC voltage
the CPU will detect the zero point of thi
zero point can not detected for 400 ms, then it will display the fault code , the complete
machine will stop working and can not be started .
