Error Codes
There are various types of errors, some are blocking (i.e., Manual & Auto Reset type) and required intervention to restore
boiler operation, while others are informational (i.e., Warnings) and do not directly block boiler operation.
Error Types:
•
Manual Reset – must be cleared from the Home Screen (by selecting “Press to RESET”) or the Errors -> Active
Errors menu (by selecting “Press to reset active errors”) before the boiler will attempt to resume normal
operation.
•
Auto Reset – block the boiler from firing but will reset automatically when the error condition is resolved.
•
Warning – are informational only and do not block the boiler from firing; however, the warning may be an
indication that certain functions are no longer operational and therefore need attention.
