It mounts directly on the oil burner and is intended for use in intermittent ignition applications with hydronic heating systems. The unit features dual temperature limits: a fixed high limit for burner cutout and an adjustable low limit with circulator differential for maintaining boiler temperature. With its integrated safety timing, auxiliary ZC/ZR terminals for zone control, and compatibility with the C554A cadmium sulfide flame detector, the R8182D1079 ensures reliable flame supervision and heating control. Key Features: Integrated Control Design: Combines Protectorelay safety, high-limit, and low-limit/circulator control in one compact unit. Intermittent Ignition Compatibility: Specifically designed for oil-fired hydronic systems using intermittent ignition. Dual Temperature Limits: Provides 10°F fixed high limit and adjustable 10–25°F low-limit differential for efficient boiler management. Automatic Safety Reset: Includes a 45-second safety timing period with manual reset required after flame failure. Auxiliary ZC/ZR Terminals: Allow zone control through an external R845A switching relay. High Pressure Tolerance: Rated for up to 200 psi on immersion wells and 100 psi for direct immersion. Thermal and Electrical Protection: Operates within 0–95% RH non-condensing and up to 250°F at element temperature. UL and CSA Certified: Approved for safety and reliability in residential and light commercial applications. Convenient Mounting: Vertical mounting design for direct burner installation with heat-conductive compound included. Low Power Consumption: Operates at only 9 W, ensuring energy-efficient system control. The R8182D1079 delivers the reliability and precision required for hydronic heating systems requiring integrated safety and temperature control.
