C. Boiler Test Mode
This function is intended to simplify gas adjustment. The
following tables include recommended combustion settings
by fuel type and boiler fan speeds. Automatic modulation does
not take place while the controller is in Test Mode. However,
the boilers will modulate down if the program set point is
reached while running in Test Mode. It is recommended to
enter Test Mode with the largest load possible to create such a
heat demand that Test Mode will not be interrupted. To enter
Test Mode press

ENTER
simultaneously.
NOTE:
The boiler will automatically exit Test Mode after 20
minutes of operation.
To leave Test Mode press

Part 11 - 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 qualified 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.
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.
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 off.
Failure to make these checks could result in substantial
property damage, serious personal injury, or death.
