Schneider Electric (Barber Colman) TC-1101 Thermostat

The Schneider Electric (Barber Colman) TC-1101 is a commercial-grade two-position electric room thermostat engineered for high-accuracy on-off control of HVAC equipment, including fan coils, motor starters, and contactors. Designed for versatility, this SPDT snap action switch supports both low and line voltage thermostat applications (24 to 277 VAC), making it a standard choice for building automation and industrial climate control. With a setpoint range of 55 to 85°F and a fixed 2°F differential, the TC-1101 provides stable bimetal sensing to ensure consistent mechanical performance in NEMA 1 environments. This unit is the direct replacement for EYDA-1 and serves as the primary Barber Colman TC-1101 series model. It arrives complete with a beige cover, dial inserts for multiple configurations (including -400 and -404), and stop pins to prevent unauthorized setpoint adjustment. Whether performing a TC-1101 series installation or a legacy system retrofit, this thermostat facilitates rapid mounting to standard 2"x4" switch boxes.

• Universal Compatibility: Operates as a line voltage room thermostat or a low voltage controller, reducing the need for multiple stock units.
• Precise Switching: Features a high-reliability SPDT snap action switch to prevent arcing and ensure clean contact engagement for motor loads.
• Retrofit Ready: Engineered as the official TC-1101 replacement for EYDA-1, matching existing footprints for fast field swap-outs.
• Operational Security: Includes adjustable dial stop pins to limit the temperature range, preventing energy waste in commercial spaces.
• Rugged Enclosure: NEMA 1 rated construction with a brushed bronze cover insert option for durable, professional presentation.

• What is the difference between the TC-1101 and the EYDA-1? The TC-1101 is the modern, direct replacement for the legacy EYDA-1, offering the same electrical ratings and physical mounting footprint.
• Can this unit handle both heating and cooling? Yes, the SPDT switch configuration allows the TC-1101 to be wired for either single-stage heating or single-stage cooling applications.
• Does it include everything needed for mounting? The package includes the thermostat, a standard beige cover, various faceplate inserts, and 5/64" Allen screws for securing the assembly to a vertical 2"x4" box.
