Product Description
The Honeywell RM7838A1014 is a microprocessor-based integrated burner control module designed for single-burner, semi-automatic industrial gas, oil, or combination fuel applications. It ensures safe burner operation by delaying fuel admission until a flame is proven and monitoring it throughout the run period. It replaces older R4138 series controls and offers advanced diagnostics, safety checks, and communication capabilities.
