SECTION XXIII: INDOOR AND OUTDOOR UNITS ERROR CODES
This section identifies error codes that appear on the front panel of the indoor unit or outdoor unit control. Many of the error codes will automatically clear themselves when the error no longer exists. However some error codes may require disconnecting power to the system at the unit disconnect switch or circuit breaker in order to clear them and to resume normal system operation.
*The temperature readout (either temperature setpoint or indoor ambient) will be replaced by an error code if there is a malfunction. If multiple errors are detected, the display will alternate between each error code.
NOTE:
No history is kept on past error codes.
