APPENDIX B: BURNER CONTROL COMMISSIONING
The S7800 display module is required to commission the following features in 7800 SERIES burner control modules that
support them:
•Valve proving system
• Post purge timing
Not all 7800 modules support these features. Some models may support both features while some may only support one
or the other. These safety features are configured using a commissioning procedure that interacts with the installed
burner control module. The commissioning procedure is driven by the burner control module since it is aware of the
features it supports and is responsible for their settings. Models that support either one of the features can be identified
in the display module by one of three methods (see Fig. 64):
• “SETUP NEEDED” state is displayed on the Home page
• “BC Commissioning” line is present on the Home page
• “BC Commissioning” line is enabled for navigation on the Display setup menu page
Fig. 64. Commissioning applicable for burner control module
When “SETUP NEEDED” is displayed on the Home page the burner control module will not fire until commissioning is
performed. Commissioning can only be performed when the burner control module is in this condition or when it is
locked out or in a STANDBY state. Commissioning is not allowed when the burner control module is in any other state. “BC
Commissioning” line is only present on the Home page when the burner control module supports it and it is in one of the
states listed above.
Commissioning is initiated from either the Home or Display Menu pages (see Fig. 65). The BC commissioning setup
menu displays showing the current settings of the three possible commissionable parameters:
•Postpurge time
• Valve proving when option (when valve proving is executed)
•Valve proving time
Postpurge time specifies how long the burner should be purged after it leaves the “RUN” state. Valve proving (VP) is a
feature that provides a systematic way of testing the valve seat integrity to assure the valves are indeed closed when the
system is off-line or idle.
