Clearing Error Codes

If error codes are observed during Diagnostic Mode, a non-flashing SERVICE annunciator will appear on the LCD
when Diagnostic Mode ends, indicating error codes are still registered (See Figure 3-56). To clear a non-flashing
SERVICE annunciator and the error codes, the problem must be corrected and the unit must be ON. Then, the Bell
ON/OFF key must be pressed and held for fifteen (15) seconds. The control will emit a short "beep" when the SER-
VICE annunciator and error codes are cleared. (See Figure 3-57)
