Honeywell R8182D111 Combination Protectorelay and Hydronic Heating Control with High LimitHoneywell R8182D111 Combination Protectorelay and Hydronic Heating Control with High Limit


Immersion type Aquastat 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. 8*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.
