Part 12 - Troubleshooting
A. Boiler Error and Fault Codes
If any of the sensors detect an abnormal condition, or an internal
component fails during the operation of the boiler, 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 boiler. In this case, the boiler 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 boiler will not start until a qualied technician has repaired
the boiler 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. Boiler 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. Boiler 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 boiler.
2. Note the displayed fault code and refer to Section D for an explanation
of the message along with several suggestions for corrective actions.
DO NOT USE THIS APPLIANCE IF ANY PART HAS BEEN
SUBMERGED IN WATER. Immediately call a qualied service
technician. The appliance MUST BE replaced if it has been
submerged. Attempting to operate an appliance that has been
submerged could create numerous harmful conditions, such as
a potential gas leakage causing a re and/or explosion, or the
release of mold, bacteria, or other harmful particulates into the
air. Operating a previously submerged appliance could result in
property damage, severe personal injury, or death.
NOTE: Appliance damage due to ood or submersion is considered
an Act of God, and IS NOT covered under product warranty.
When servicing or replacing components that are in direct contact
with boiler water, be certain that:
• There is no pressure in the boiler. (Pull the release on the relief
valve. Do not depend on the pressure gauge reading.
• The boiler water is not hot.
• The electrical power is disconnected.
• The gas is shut o.
Failure to make these checks could result in substantial property
damage, serious personal injury, or death.
Label all wires prior to disconnecting them when servicing the
boiler. Wiring errors can cause improper and dangerous operation.
Failure to follow these instructions may result in property damage
or personal injury.
If overheating occurs or the gas supply fails to shut o, do not turn
o electrical power to the circulating pump. This may aggravate
the problem and increase the likelihood of boiler damage. Instead,
shut o the gas supply to the boiler at the gas service valve. Failure
to do so may result in property damage, personal injury, or death.
NOTE: If system return temperatures are maintained below the dew
point, condensation will form on the inside of the boiler cabinet and
cause some internal sheet metal components to rust.
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.
