PART 11 – SHUTDOWN
A. SHUTDOWN PROCEDURE
If the burner is not operating, disconnect the electrical supply.
If the burner is operating, lower the set point value to 70
o
F and wait for the burner to shut off. Continue to wait for the combustion
blower to stop, so all latent combustion gases are purged from the system. This should take a maximum of 40 to 90 seconds.
B. VACATION PROCEDURE
If there is danger of freezing, change the set point to 70
o
F. DO NOT turn off electrical power. If there is no danger of freezing, follow
“Shutdown Procedure”.
C. FAILURE TO OPERATE
Should the burner fail to light, the control will perform two more ignition trials prior to entering a lockout state. Note that each
subsequent ignition trial will not occur immediately. After a failed ignition trial, the blower must run for approximately 10 seconds to
purge the system. Therefore, a time period of approximately 40 to 90 seconds will expire between each ignition trial.
If the burner lights during any one of these three ignition trails, normal operation will resume. If the burner lights, but goes off in about 4
seconds, check the polarity of the wiring. See electrical connection section.
If the burner does not light after the third ignition trial, the control will enter a lockout state. This lockout state indicates that a problem
exists with the boiler, the controls, or the gas supply. Under such circumstances, a qualified service technician should be contacted
immediately to properly service the boiler and correct the problem. If a technician is not available, depressing and holding the RESET
button for more than 1 second will remove the lockout state so additional trials for ignition can be performed. The unit will try to re-light
once every 6 minutes.
PART 12 – TROUBLESHOOTING
A. BOILER ERROR CODE
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 on 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
When an error condition occurs, the controller will display a description and code on the display readout. These error messages and
their recommended corrective actions are described in Section D.
