Diagnostic Mode Indicators

If "EE" is observed in the left display area during Diagnostic Mode - The thermistor, or its wiring in the location
indicated by the code at right is open or shorted (See Figure 3-32).
Figure 3-32. "EE" Observed in Diagnostic Mode = Thermistor (or its wiring) Fault in Location Indicated
If "EC" is observed in the right display area during Diagnostic Mode - Numbers at left are "Error Codes" (See
Figure 3-33). Error Codes indicate problems logged by specific components. If error codes are logged, they will
appear before temperature readings and can be toggled through with the temperature readings as described on the
previous page. (See Error Code Table below.)

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. (See Figure 3-34)
Press and hold for 15 seconds
