TROUBLESHOOTING
XFyre Error Codes
If any of the sensors detect an abnormal condition or an internal component fails during the operation of the XFyre, the display may show an error code. This code may either 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 the result of a condition that the controller has evaluated as not safe to restart the unit. In this case, the unit control will be locked out, requiring the maintenance person to manually reset the control by pressing the ESC/RESET key for more than 1 second. Typically, if the display has a code beginning with F followed by 2 numbers the XFyre is locked out. If the display has a 3 letter code it is the result of a temporary condition.
Heater Errors
When an error condition occurs, the controller will dis- play an error code on the display module. These error codes and several suggested corrective actions are included in the XFyre Fault Text section on the follow- ing page.
Heater Faults
45
1.When a fault condition occurs, the controller will illuminate the red “fault” indication light and display a fault code in the format. The alarm output will also be activated. Most fault conditions will also cause the boiler pump to run in an attempt to cool the unit.
2.Note the fault text and refer to the XFyre Fault Text section for an explanation of the fault along with several suggestions for corrective actions.
3.Press the ESC/RESET key to clear the fault and resume operation. Be sure to observe the opera- tion of the unit for a period of time to ensure correct operation and no reoccurrence of fault codes.
DANGER: When servicing or replacing components that are in direct contact with the 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 off.
