Models that do not use the Heater Function

The heater function is not available for these models that have a software revision level 

starting less than 5. The heater function will not work regardless of the setting in the Heater 

Mode setup. Operating Temperature from - 32 °F to 140 °F (0 °C to 60 °C).

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:
