Red Dot RD-5-11031-0P Preset Thermostatic Switch, also listed as 71R2200, uses a fixed setting with a 31.5-inch capillary tube to regulate electrical circuits based on temperature. The device provides a preset (non-adjustable) setpoint range of 31°F to 39°F, making it suitable for precise cooling and refrigeration controls. With its long 31.5-inch sensing tube, it supports reliable temperature responsiveness in routed or space-constrained installations.
