Schneider Electric (Barber Colman) TC-1101-500 Thermostat

Ensure precise climate control on your next service call with the Schneider Electric Barber Colman TC-1101-500. This bimetal, two-position electric room thermostat is a standard-tier solution for applications requiring on-off control of fan coils, motor starters, contactors, and two-position electric actuators. Designed for high-reliability switching, this unit features a SPDT snap action switch that supports both low and line voltage (24 to 277 VAC) configurations. The setpoint range of 55 to 85°F (13 to 29°C) provides a versatile operating window for commercial and residential zones.

As the primary EYDA-2 replacement thermostat, the TC-1101-500 is engineered with an integrated heat anticipator to minimize temperature overshoot and maintain a tight 2°F differential. The NEMA 1 rated enclosure is designed for surface or flush mounting into a standard 2"x4" electrical box, simplifying the HVAC thermostat installation process. This model comes complete with a beige plastic cover and inserts, enabling field conversion to the -400 and -404 series configurations if required by specific site conditions.

• Universal Voltage Compatibility: Rated for low or line voltage applications from 24 VAC to 240 VAC (with 277 VAC nominal supply capacity) for HVAC system control flexibility.
• High-Current Switching: The SPDT snap action switch handles heavy pilot duty (40 VA @ 24V) and heating loads up to 4.4A @ 120V.
• Precise Cycling: Features parallel heat anticipation to improve system response time and occupant comfort.
• Field Adjustability: Includes dial stop pins to limit the setpoint range and secure the 55-85°F dial against unauthorized adjustments.
• Direct Retrofit: Functions as the factory-authorized TC-1101-500 replacement for the legacy Barber Colman EYDA-2 model.

Is the TC-1101-500 compatible with 277V systems?
Yes, the internal SPDT switch is rated for typical line voltage applications, including nominal 277 VAC supplies, making it suitable for larger commercial fan coil units.

Does this unit require a separate subbase for mounting?
No, this thermostat is designed for direct surface or flush mounting in a standard 2" x 4" vertical switch box. It includes the necessary cover and mounting screws for a complete install.

Can I use this to replace a legacy Barber Colman EYDA-2?
Yes, the TC-1101-500 is the direct technical replacement for the EYDA-2, maintaining the same bimetal sensing and electrical specifications.
