Revert to Pilot - LMV37 only
Introduction
Revert to pilot is a feature on the LMV37 that allows the burner to re-light the pilot and close
the main gas valves (V1 and V2). This is done for two key reasons:
• Eliminating energy losses due to postpurge and prepurge
• Minimizing the time from a demand signal to burner heat production
Procedure
1. Wire the LMV3 and RWF55 load controller as shown below in Figure 12.
