Schneider Electric (Barber Colman) TP-1011 Thermostat

The Schneider Electric (Barber Colman) TP-1011 is a high-precision proportional thermostat designed for 24 Vac HVAC control systems. This SPDT switching controller provides accurate temperature regulation within a 55°F to 85°F range, making it a standard for commercial space heating and cooling applications. As the direct replacement for GYDT-1 and GYDT-1X15 models, this unit ensures seamless integration into existing pneumatic-to-electric or electronic control loops without the need for extensive field modifications. The device utilizes a bimetal sensing element to provide proportional control of proportional actuators, valves, and dampers. Its rugged design is built for industrial environments where reliable low voltage temperature control is required. For technicians managing legacy system maintenance, the TP-1011 offers consistent thermal sensitivity and a proven mechanical interface, ensuring system stability and precise load tracking in proportional terminal unit configurations.

Key Benefits

• Broad Compatibility: Functions as the factory-authorized replacement for Barber Colman GYDT-1 series, ensuring identical footprint and wiring logic.
• Precision Control: Features a proportional action mechanism that prevents short-cycling and maintains tighter setpoint tolerances than standard on/off thermostats.
• Reliable Switching: Equipped with SPDT contacts rated for 24V applications, suitable for controlling a wide variety of HVAC floating point actuators.
• Ease of Installation: Designed with standard terminal designations to simplify field wiring for HVAC contractors and facilities engineers.

Common Questions

Is the TP-1011 compatible with 120V systems?
No, this is a 24V low voltage thermostat. Using this device with line voltage will result in immediate component failure.

Can I use this to replace a GYDT-1X15?
Yes, the Schneider Electric TP-1011 is the designated technical successor for the GYDT-1X15, maintaining the same electrical specifications and 55-85 degree range.

Does this unit support cooling-only applications?
The SPDT switching capability allows it to be wired for heating, cooling, or changeover applications depending on your specific proportional control requirements.
