Barber-Colman Co. TC-5141 Thermostats and Accessories

Barber-Colman TC-5141 is a low-temperature duct thermostat that provides a two-position (on/off) output for controlling duct-mounted equipment in HVAC systems, including dampers, fans, or actuators that respond to fixed-temperature setpoints. This unit incorporates a spot manual reset and operates over a fixed temperature range from 34 to 60 degrees Fahrenheit, enabling a straightforward, fixed-threshold control suitable for cooling or return-air duct applications, with the setpoint accessible through standard mounting and wiring practices used for Barber-Colman accessories. As part of Barber-Colman's Thermostat Accessories, TC-5141 is designed for duct and air-handling applications, offering a compact, mechanically simple switch that can be wired into dampers, fans, or related controls that require a fixed setpoint response. Its two-position operation means the output changes state when the sensed duct temperature crosses the setpoint, providing on/off control in commercial or light-industrial HVAC environments. Barber-Colman is a long-standing HVAC controls brand, and the TC-5141 appears in catalogs and listings alongside other duct thermostats and thermostat accessories.
