Ballu Error Codes List
- E1, E2, E3, E4 - the temperature sensor is shorted or broken (indoor or outdoor unit, condenser temperature, evaporator temperature)
- E6 - protection of the external unit has worked
- E8 - clogged electrostatic filter
- P4 - error on the evaporator sensor, too low / high temperature (the compressor switches off automatically)
- P5 - error on the capacitor sensor, too low / high temperature (the compressor switches off automatically)
- P6 - the defrost or delay mode of the temperature of the internal heat exchanger is activated
- EA - the firmware has flown, the EEPROM is faulty (determined empirically, replacing the ROM chip with the firmware removed the error)
Error codes of the BSC series; BV; BR
- E1 - error of the internal temperature sensor
- E2 - error of the evaporator temperature sensor
- E5-system entered protection mode by mistake of the outdoor unit
- E6 - error of the fan motor of the indoor unit
