Codes
- 1Error codeReset the power to the outdoor unit PCB. Wait for five (5) minutes. The number of the indoor units installed is displayed. Example: Heat recovery unit → Number of indoor units. Are the numbers of indoor units connected to the NO outdoor unit and that displayed on the LED the same? Check the central control addresses of the indoor and heat recovery units. YES Manual pipe detection is complete. Make sure to reset the power to the outdoor unit if the central control unit is changed
