Description
Immersion type Aquastat controller and oil burner primary control provides high limit and low limit/circulator control for oil-fired hydronic heating systems.

Specifications
  • 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.
