Honeywell Thermal Solutions FSG RM7890A1056 Burner Control

The FSG RM7890A1056 Burner Control by Honeywell Thermal Solutions is a microprocessor-based, integrated control that delivers precise flame establishment, fast startup, and dependable safety for single-burner systems. It is ideal for on-off primary control with automatically fired gas, oil, or a combination fuel, offering robust sequencing, fault detection, and easy field diagnostics.

Designed for reliability in harsh environments, this 120 V AC control fits a compact 5 x 5-1/4 x 5 in enclosure and supports a pilot-type intermittent cycle. The flame establishment period is 4/10 second for the pilot, followed by the intermittent main flame, delivering precise sequencing and safe startup. The unit operates across -40 to 140 F during shipping and storage and carries UL, CSA, FCC, SRE, and FM approvals, enabling straightforward integration into single-burner gas, oil, or combination systems.
