PRODUCT DESCRIPTION
EC7850A1072 Burner Control Relay Module
Honeywell EC7850A1072 is a microprocessor-based burner control relay module in the 7800 Series. It provides automatic burner sequencing and flame-safety supervision for compatible single-burner gas, oil or combination-fuel systems.
The module coordinates prepurge, ignition, flame establishment, firing and shutdown with the selected subbase, flame amplifier and purge timing card. Five status indicators and nonvolatile fault history support diagnostics. The EC7850A1072 timing arrangement includes five-second pilot stabilization and a two-second postpurge; required accessories are selected separately.
