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™.
