PROVIDES PREIgnition, LOCKOUT, HIGH & LOW FIRE INTERLOCKS, SELECT PREPURGE TIMINGS, 4 OR 10 SEC PFEP, PREIgnition CHECK DURING POSTPURGE, 5 LEDS, & 5 FUNC. RUN TEST Switch. Overview The Honeywell RM7840L1075 is a microprocessor-based programming burner control from the 7800/7840 Series, engineered for industrial and commercial single-burner applications. It provides precise sequencing, flame supervision, post-purge logic, and built-in self-diagnostics. Designed for dependable operation, this module supports low-fire/high-fire proving and requires a compatible display module for programming and monitoring. This control delivers reliable performance in demanding burner management environments where safety, efficiency, and serviceability are critical. Features Functions include automatic burner sequencing, flame supervision, system status indication, system or self-diagnostics and trouble shooting. Access for external electrical voltage checks. Application flexibility and communication interface capability. Five LEDs provide sequence information. Power LED blinks fault code on Lockout. Five function Run/Test Switch. Interchangeable plug-in flame amplifiers. Local or remote annunciation of operation and fault information (optional). Nonvolatile memory retains history files and lockout status after loss of power. Compatible with existing Honeywell flame detectors. RM7800 Requires S7800A1142 Keyboard Display Module. Keyboard required to setup Valve Proving Feature and change post purge time.
