Schneider Electric (Barber Colman) 2212-119 Thermostat

The Schneider Electric (Barber Colman) 2212-119 is a high-performance reverse acting pneumatic thermostat engineered for proportional control of dampers and valve actuators in two-pipe pneumatic systems. Designed for professional building automation and environmental control, this unit features a bimetal sensing element and a pilot-operated relay with pneumatic feedback to ensure exceptional accuracy and control stability. Operating across a 55 to 85F temperature range, it provides reliable HVAC pneumatic control without the restriction of dial limit stops, allowing for full-range adjustment via the integrated serrated thumbwheel. This industrial-grade Bimetal Pneumatic Thermostat is constructed with die-cast aluminum and stainless steel components to withstand demanding mechanical environments. For technicians performing retrofits or maintenance, the 2212-119 serves as the heavy-duty direct replacement for Barber Colman 2210-016, 2212-019, 2212-303, and 2212-304, ensuring seamless pneumatic thermostat compatibility and simplified field installation.

• Precise Proportional Control: Utilizes a highly sensitive bimetal element for stable linear operation of pneumatic devices.
• Versatile Replacement: Consolidates inventory as a direct field replacement for legacy 2210 and 2212 series models.
• Adjustable Throttling Range: Features an adjustable 2 to 12 F throttling range to fine-tune system response.
• Durable Construction: Built with fabric-reinforced Neoprene diaphragms and rugged internal filters for branch connections.
• Low Air Consumption: Efficient 0.009 SCFM air usage at 20 PSI optimizes compressor run time.

Common Questions

How do I calibrate the branch line pressure on the 2212-119?
With the cover removed, use a 1/16-inch Allen wrench to adjust the calibration screw until the branch pressure gauge reads 9 PSIG when the setpoint matches the current ambient room temperature.

What is the maximum supply air pressure for this thermostat?
The unit is designed to handle a maximum operating pressure of 30 PSIG, typically calibrated for standard 20 PSI pneumatic main lines.

Can this model be used in direct acting applications?
No, the 2212-119 is specifically a reverse acting (RA) controller. For direct acting (DA) requirements in the same series, the 2212-118 is the appropriate functional equivalent.
