3. Discharge temperature protection
There is a temperature sensor on discharge pipe, when temperature on discharge pipe exceeded
the limit 115℃, system control will shut down the compressor and the display board will show the
error code.
4. Lower voltage protection
When AC voltage <160V, DC voltage<170V, unit will be shut down for protection and recover
while the AC voltage ˃170 V, DC voltage ˃190V.
5.
Over voltage protection
When AC voltage ˃ 275V, DC voltage ˃400V unit will be shut down and recover while AC
voltage<255V, DC voltage<390 V.
6. Over current protection
When the current of outdoor unit is overload, controller will drop the operation frequency or shut
down the unit immediately and show error code.
7. Condenser temperature protection
When condenser temperature≥ 65℃ and keep 10s, the air conditioner will shut down, and show
error code, and recover while condenser temperature<52℃ and the compressor stop for
3minutes.
8.
IPM module protection
IPM module has high temperature & over current protection itself, if there is signal feedback to
IPM, the outdoor unit will shut down, LED on outdoor PCB will show the error code.
9. Evaporator freeze protection.
When evaporator temperature<2℃, the controller will drop compressor operate frequency.
When evaporator temperature<0℃ and keep 1 minute, the expand valve of the unit will stop.
When all of the operating unit enter freeze protect, the compressor will stop and recover while
evaporator temperature and stop for 3 minutes.
