controller and oil burner primary control
provides high limit and low limit/circulator control for oil-fired
hydronic heating systems.
• Use in intermittent ignition applications.
• Capable of zone control with zone valves.
• Circulator zone control with ZC and ZR terminals on R8182D,E,H,J.
• Flame failure during the running cycle results in a 45 second
attempt to restart.
• If unsuccessful, safety shutoff occurs, requiring manual reset
before burner can be restarted.
• R8182D,E,F mount directly on burner; R8182H,J mount on 4 x 4 in.
junction box and include 5 ft (1.5 m) armored capillary with remote
sensor.
• C554A Cadmium Sulfide Flame Detector and a 24 Vac thermostat
required.
• Auxiliary ZC and ZR terminals may be used to provide circulator
zone control through an R845A Switching Relay.
