The controller offers a high limit range of 130°F to 240°F and a low limit range of 110°F to 220°F, with a differential adjustment of 10°F to 25°F on the circulator circuit. It features a 45-second safety switch lockout, burner AFL rating of 4.4 A at 120 VAC, and supports zone control via ZC and ZR terminals. Mounted on a 4 × 4 in. junction box, it includes a 5 ft armored capillary sensor and supports manual reset after safety shutdowns. Compatible with cadmium sulfide flame detectors and 24 VAC thermostats, the R8182H1070 ensures safe, efficient temperature regulation and control. Key Features: Dual Temperature Range: High limit range: 130°F to 240°F; Low limit range: 110°F to 220°F. Adjustable Differential: 10°F fixed (high limit); 10°F to 25°F adjustable (low limit/circulator). Safety Lockout Feature: 45-second safety switch timing with manual reset required after flame failure. Mounting Configuration: Junction box mounting with 5 ft armored capillary and remote sensor. Ignition Compatibility: Designed for intermittent ignition applications with flame safeguard. Electrical Ratings: Burner AFL: 4.4 A @ 120 VAC; Ignition load: 360 VA; Max power consumption: 9 W. Zone Control Support: Compatible with ZC and ZR terminals for zone valve control. Environment Tolerance: Operates in 0–95% RH (non-condensing) and up to 250°F ambient. Dimensions: 7-1/8″ height × 5-1/4″ width × 3-7/16″ depth. Max Operating Pressure: 200 psi (immersion well) or 100 psi (direct immersion). The R8182H1070 offers precise hydronic control and integrated safety features ideal for advanced residential heating systems.
