Schneider Electric (Barber Colman) 2214-121 Thermostat

The Schneider Electric 2214-121 is a direct acting day/night pneumatic thermostat designed for precise proportional control of valves and actuators in HVAC systems. This unit serves as the direct replacement for the 2214-021, facilitating a seamless drop-in upgrade for legacy Barber-Colman installations. Operating within a setpoint range of 50 to 85°F (10 to 30°C), this thermostat utilizes a dual-setpoint mechanism to maintain energy efficiency through scheduled setbacks. It features a high-volume pneumatic relay for rapid response to load changes and includes a 1/8" NPT connection. The bimetal sensing element ensures long-term calibration stability in demanding commercial environments. For technicians managing pneumatic control systems, the 2214-121 provides reliable day/night temperature regulation with a branch pressure range of 3 to 15 psi, making it an essential component for maintaining building automation system performance and comfort levels in retrofitted facilities.

• Direct compatibility with established Barber-Colman pneumatic footprints ensures reduced labor time during field replacements.
• Dual-temperature control allows for automated night setback, significantly reducing energy consumption in commercial zones.
• Robust direct acting logic provides consistent 15 psi output when the ambient temperature rises above the setpoint.
• Integrated aspiration port allows for improved air sampling and more accurate thermal sensing in wall-mounted applications.
• Field-adjustable throttling range provides the flexibility to fine-tune proportional control loop sensitivity.

Is the 2214-121 compatible with older Barber-Colman 2214-021 models?
Yes, the 2214-121 is the engineered direct replacement for 2214-021, utilizing the same mounting hardware and pneumatic port configurations for straightforward integration.

What is the air consumption rate for this pneumatic thermostat?
The unit typically consumes 20 scim (5.5 mL/s) of air, making it efficient for large-scale pneumatic control networks without overloading the compressor.

How do you calibrate the day/night setpoints?
Calibration is performed via the dual-adjustment dials under the cover, requiring a pneumatic calibration kit to verify branch pressure alignment at the 9 psi midpoint.
