The Honeywell RM7800/RM7840 Relay Modules are 

microprocessor-based integrated burner controls for 

automatically fired gas, oil, or combination fuel single burner 

applications. The RM7800/RM7840 Relay Modules are used 

for UL/CSA On/Off, UL/CSA Modulating, and FM/IRI 

Modulating burner applications. The RM7800/RM7840 system 

consists of a Relay Module. Keyboard Display Modules 

(standard with RM7800), Dust Cover (standard with RM7840), 

Subbase, Amplifier, and Purge Card. Options include DATA 

CONTROLBUS MODULE™, Remote Display Mounting, First-

Out Expanded Annunciator and Communications through 

Modbus™.

Functions provided by the RM7800/RM7840 include 

automatic burner sequencing, flame supervision, system 

status indication, system or self-diagnostics and 

troubleshooting. The RM7800/RM7840 is a solid state
