Honeywell Thermal Solutions FSG RM7840L1018 Burner Control

The FSG RM7840L1018 Burner Control from Honeywell Thermal Solutions is a microprocessor-based, integrated control designed for single-burner applications. It delivers precise flame establishing periods—4/10 seconds for pilot and 10/15 seconds for main—together with an interrupted pilot configuration and built-in self-diagnostics for safer operation.

Engineered to handle gas, oil, coal, or combination fuels, this 120 V AC controller supports automatic burner sequencing, flame supervision, and real-time system status indication. Its compact 5" W x 5-1/4" D x 5" H enclosure and wide operating temperature range (-40 to 140 °F) ensure reliable performance during shipping, storage, and field use. The RM7840L1018 carries robust approvals for UL, CSA, FCC, CSD, SRE, and FM, reflecting strict safety and compatibility standards.
