Burner Control Honeywell EC 7850 A 1072 – 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 ControlBus™ 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.
