• Remanufactured with 100% pure, solid silver pyrostat contacts for longer on-the-job service life
• Backed by 2-year warranty
• All new stack relays contain brass contacts covered with a slight silver plating, it wears off as the contacts open and close, exposing the brass surface over time, the exposed surface is a poor conductor and may result in relay failure and nuisance callbacksSid Harvey Item #:R5R: Replaces Part #:'s : 0R541R,

• 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 sec attempt to restart
• If unsuccessful, safety shutoff occurs, requiring manual reset before burner can be restarted
• C554A cadmium sulfide flame detector and a 24 VAC thermostat required
• Includes auxiliary ZC and ZR terminals may be used to provide circulator zone control through an R845A switching relay, horizontal case
• Maximum 250 deg F at element, 15 deg F fixed high limit differential temperature
• 45 sec safety switch timing
• 1/2"-14 NPT well spud size
• 0.2 amp anticipator setting
• 1-1/2" insulation depth,
