Honeywell RA890G1229 Primary Control

Honeywell RA890G1229 Primary Control. Primary control provides solid state, electronic flame safeguard protection for industrial and commercial single or dual fuel burners applications using Ultraviolet flame detectors. Design for interrupted ignition with intermittent pilot on gas burners, and interrupted or intermittent ignition on oil burners. Use with a C7027, C7035 or C7044 Minipeeper Ultraviolet Flame Detector for flame sensing. Recycles if flame signal lost while in Run. Failure to establish pilot results in a lockout. Safe-start check prevents start-up if flame-simulating failure occurs in flame detector circuit. Includes SPDT alarm contacts. Solid state circuitry, eliminates warm-up and increases resistance to vibration. Mounts and removes easily through use of captive mounting screws. Mounting base is made of strong thermoplastic.
