71R3200 Red Dot Preset Fixed Thermostat with 24 in. Capillary

When mobile HVAC systems require consistent, repeatable cycling, a preset thermostat is the right solution. The Red Dot 71R3200 is a fixed (non-adjustable) thermostat designed to maintain a defined temperature range without operator adjustment, helping ensure stable and predictable performance.

This thermostat features a 24-inch capillary tube and operates within a 31°F–39°F temperature range. In addition, the 8°F clutch cycle range helps control compressor cycling in a smooth, repeatable manner. A flange-base mounting design supports standard installations, while the optional side-mount configuration adds flexibility for tighter or alternative mounting locations.
