Honeywell RM7850A1019 burner control
The Honeywell EC/RM7830, EC/RM7850 Relay Module is a microprocessor-based integrated burner control for automatically fired gas, oil, or combination fuel burner on/off
(EC/RM7830A) or full modulation (EC/RM7850A) power burner applications. The EC/RM7830A or EC/RM7850A system consists of the relay module, wiring subbase, amplifier and purge card. Options include the keyboard display module (KDM), personal computer interface, Data Control Bus Module, and Combustion System Manager Software. The KDM can be mounted on the relay module or on the face of a
panel door. The KDM can also be remotely mounted from the panel if this is approved for the application.
The EC/RM7830, EC/RM7850 is programmed to provide a level of safety, functional capability and features beyond the capacity of conventional controls.
The basic functions of the EC/RM7830A, EC/RM7850A includes automatic burner sequencing, flame supervision, system status indication, system or self-diagnostics, and
troubleshooting.
