71R2250 Rotary Variable Thermostat, 36″ Capillary (34°F–52°F Range)

Description

When temperature control needs to stay steady, the thermostat is the key. The Red Dot 71R2250 rotary thermostat is a variable-type control designed with a 36-inch capillary and a 34°F–52°F operating range.

Because it’s a rotary control, it’s easy to adjust, and it supports consistent system cycling. In addition, it provides a 5°F clutch cycle range, which helps maintain stable performance in mobile HVAC systems.
