Barber-Colman TC-282-174 Three Stage Thermostat

Barber Colman TC-282-174 Three-Stage Remote-Bulb Thermostat is a stand-alone HVAC control that executes three heating or cooling stages via a remote bulb sensing element. The model covers a 10°F to 90°F setpoint range and uses a 6-foot capillary to position the bulb away from the control body for flexible installation. This variant (TC-282-174-CS&S) is described as “3-Stage Remote Bulb – 10°F to 90°F w/o Mounting Nut,” and it employs a single SPDT electrical switch to drive the staged outputs. Built for heating or cooling applications, it is part of the Barber Colman family (now Schneider Electric), a line known for bulb thermostats used in commercial HVAC and related equipment. With a weight of 3.00 lb, the unit combines a bulb-and-capillary sensing assembly with three actuated stages to provide reliable, multi-stage temperature control where remote sensing is required. Typical installations include furnaces, air handlers, and other HVAC components that benefit from remote temperature sensing and a 10–90°F operating window across the TC-282 series.
