Honeywell RM7840L1075 burner control

Honeywell RM7840L1075 burner controller designed for automatic systems with a single burner, running on gas, liquid fuel (fuel oil), coal or combined fuels. Honeywell RM7840L 1075 burner controller provides a higher level of safety, better functionality and technical data compared to standard regulators.

Honeywell RM7840L1075 burner control automatically sets the burner operation sequence, monitors the flame, indicates system status, performs diagnostics, and detects faults. It allows for external electrical voltage control, has a communication interface, and offers application flexibility. Five LEDs indicate operation status. The five-function switch toggles between operational and testing modes. Removable flame signal amplifiers are interchangeable. Operation and fault information can be accessed locally and remotely. Non-volatile memory stores process history and lockout status during power failures. Compatible with Honeywell flame detectors.
