Causes
The inverter control board has internal communication problems (longertek 5 code)
Overcurrent Excess current absorption by compressor (longertek 6 code)
No load The compressor does not absorb enough current, it may turn in idle mode (longertek 7 code)
Incorrect voltage The inverter control board indicates incorrect bus voltage (longertek 8 code)
Error on start-up The inverter control board indicates incorrect start-up of the PMSM motor (longertek code 9)
IPM protection error Error on the IGBT (longertek 12 code)
EEPROM error Eeprom error on the inverter control board (longertek 13 code)
Compressor stall Cod. longertek 16
The inverter control board does not respond. It may not be powered or the serial cable could be discon-

Anomalous condition Protection frequency against over-current and overheating reduced. (code APY 20)
Cycle reverse valve faulty The cycle reverse valve could be faulty or broken. (see paragraph 8.4)
The water inlet temperature has exceeded the set_installer (H) parameter value. Probable boiler pres-
ence on same plant. At the third intervention of the pre-alarm, the machine goes into alarm mode and
blocks
This pre-alarm indicates the intervention of defrosting due to cycle reverse without having respected
the times between cycle reverses. Cycle reverse has been triggered by the pressing line gas high tem-
the pressing line gas perature partialisation threshold being exceeded, set_factory (6)-set_factory (4) = default 130°. This pre-
alarm does not cause compressor stop and does not have a limited number of interventions
This pre-alarm indicates a remote probe fault or a communication problem with the DHW control board.
remote probe The alarm is only active if the parameter (0)=2 or the parameter (8)=4 in the menu with password = 30
This pre-alarm indicates an outdoor air temperature probe fault when the DCP is present or the machine
error is in heat pump mode.
This pre-alarm indicates a condenser inlet water temperature probe fault
