Overview

The Honeywell EC7820A Relay Module is a microprocessorbased integrated burner control for automatically fired gas, oil or combination fuel single burner atmospheric with fan applications. The EC7820A system consists of the relay module, wiring subbase, amplifier and purge card. The optional keyboard display module (KDM) can be mounted on the relay module or on the face of a panel door. The KDM can also be mounted remotely from the panel if this is approved for the application.
