Part 11 - Troubleshooting
A. Error and Fault Codes
If any of the sensors detect an abnormal condition, or an internal
component fails during the operation of the appliance, the display
may show an error message and error code. This message and code
may be the result of a temporary condition, in which case the display
will revert to its normal readout when the condition is corrected, or
it may be a condition that the controller has evaluated as not safe to
restart the appliance. In this case, the appliance control will be locked
out, the red FAULT light will be lit, and the message “LOCKOUT” will
be displayed on the readout in the lower line.
The appliance will not start until a qualified technician has repaired
the appliance and pressed the RESET button for more than 1
second. If there is an error message displayed on the readout, and
the message “LOCKOUT” is not displayed and the FAULT light is not
lit, then the message is the result of a temporary condition and will
disappear when the problem corrects itself.
IMPORTANT NOTE:
If you see error messages on your display
readout, call a technician immediately, since the message may
indicate a more serious problem will occur soon.
B. Appliance Error
The controller will display an error code and message when an error
condition occurs. These error codes, descriptions, and recommended
corrective actions are described in Section D.
C. Appliance Fault
1. The controller will illuminate the red “FAULT” indication light and
display a fault code and message when a fault condition occurs. The
alarm output will also activate. Most fault conditions cause the CH
pump to run in an attempt to cool the appliance.
2. Note the displayed fault code and refer to Section D for an
explanation of the message along with several suggestions for
corrective actions.
3. Press
RESET
to clear the fault and resume operation. Be sure to
observe the operation of the unit for a period of time to assure
correct operation and no reoccurrence of fault message.
It is very important that the combustion system be set within the
recommended CO measurements listed below. Visually looking
at the burner does not determine combustion quality. Failure to
measure combustion with a calibrated Combustion Analyzer and
set the throttle within the recommended CO measurements could
result in property damage, severe personal injury, or death.
