Clearing Error Codes
If error codes are observed in diagnostic mode, a non-flashing SERVICE indicator will appear on the display when
Diagnostic Mode ends, indicating error codes are still logged. To clear a non-flashing SERVICE indicator and the
error codes, the problem must be corrected and the unit must be ON. Then, the bell key must be pressed and held
for fifteen (15) seconds. The control will emit a short "beep" when the error codes is cleared.
