Schneider Electric (Barber Colman) 2298-062 Temperature Controller

The Schneider Electric 2298-062 is a professional-grade Unit Temperature Controller designed for the proportional control of pneumatic devices in environmental control systems. Engineered as a reverse acting controller, this 2-pipe pneumatic thermostat is primarily utilized as a return air controller within induction units, fan coil units, and unit ventilators. It features a factory-calibrated setpoint range of 65 to 85°F (12.5 to 29°C) with a fixed throttling range of 4°F (2.2°C), ensuring precision and stability in HVAC pneumatic systems. This model is a direct replacement for the legacy Barber Colman 2264 Series and is compatible with the T461-301. The unit includes a mounting bracket and a high-sensitivity remote bimetal sensor system, capable of maintaining accurate regulation even at distances up to 200 feet from the controller. Adjustment is managed via a serrated thumbwheel, while the standard 1/4" O.D. tubing ports facilitate seamless integration into existing pneumatic temperature control loops.

Key Benefits:

• Versatile Application: Optimized for commercial HVAC infrastructure, specifically unit ventilators and fan coil return air control.
• Seamless Retrofit: Engineered to replace obsolete Barber Colman 2264 and Invensys pneumatic controllers without requiring major system modification.
• Enhanced Precision: Features a remote bimetal sensor that provides a high degree of sensitivity and responsiveness to temperature fluctuations.
• Easy Installation: Includes the 2298-062 mounting bracket and covers for either external or concealed adjustment setups.
• Reliable Performance: Delivers consistent reverse acting pneumatic control with an operating pressure of 20 psig and a maximum limit of 30 psig.

Common Questions:

Is the 2298-062 compatible with existing Barber Colman sensors?
Yes, this unit is designed to replace the 2264 series and utilizes standard 1/4" O.D. pneumatic tubing connections for the sensor and air lines.

What is the maximum distance for the remote bimetal sensor?
The remote sensor can be located up to 200 feet away from the Schneider Electric 2298-062 controller, provided 1/4" O.D. tubing is used and the sensor is mounted horizontally with the bimetal up.

How do I calibrate this pneumatic temperature controller?
Set the main air pressure to 20 psig and adjust the calibration screw until the test gauge indicates 9 psig. Turning the screw clockwise will increase the branch pressure.
