71R3150 Red Dot Fixed Thermostat with 16 in. Capillary

The Red Dot 71R3150 Fixed Thermostat is a non-adjustable (preset) thermostat built for mobile HVAC systems that require consistent, repeatable temperature cycling. Because the setting is fixed, it helps eliminate variability and ensures predictable performance in demanding vehicle and equipment environments.

This thermostat features a 16-inch capillary tube and operates within a 28°F–35°F temperature range, making it well suited for evaporator control applications. A 7°F clutch cycle range supports stable cycling while reducing short cycling. The flange-base mounting design, with an optional side-mount, allows flexibility when space is limited.
