Schneider Electric (Barber Colman) 2298-060 Controller

The Schneider Electric (Barber Colman) 2298-060 is a high-performance unit temperature controller designed for precise proportional control of pneumatic actuators and damper actuators. Developed as a direct modern replacement for the obsolete Barber Colman 2264 series, this unit ventilator thermostat processes return air signals to maintain tight environmental tolerances in induction units, fan coil units, and industrial ventilation systems. This two-pipe receiver-controller operates with a sensitive remote bimetal sensor system, supporting dual-pressure logic with reverse acting performance at 16 psig and direct acting output at 25 psig.

Engineered for professional HVAC pneumatic system integration, the 2298-060 features a thumb wheel setpoint adjustment for a 65 to 85°F range and a fixed 4°F throttling range. It is built to handle a maximum air pressure of 30 psig, with air consumption rates of 29.4 scim at 16 psig and 45 scim at 25 psig. The included mounting bracket allows for versatile horizontal or vertical orientation within terminal unit compartments, ensuring stable linear operation and consistent system balance for commercial HVAC contractors and technicians.

• Legacy Compatibility: Seamlessly replaces obsolete Barber Colman 2264 series controllers without extensive piping reconfiguration.
• Dual-Action Versatility: Automatically switches between reverse acting and direct acting modes based on main air pressure signals.
• High-Stability Control: Utilizes a highly sensitive remote bimetal sensor to minimize offset and ensure accurate environmental control.
• Rugged Design: Built for industrial HVAC environments with a linear operation profile across the full setpoint range.
• Installation Ready: Includes a versatile mounting bracket and hardware designed for rapid field deployment in structural members or terminal unit compartments.

How do I calibrate the switchover point on the 2298-060?
To adjust the switchover, set the main air pressure to 21 psig and rotate the setpoint adjustment fully. Adjust the switchover calibration screw until the branch pressure drops to 0 psig to ensure proper transition between modes.

What is the maximum distance for the remote sensor?
The remote bimetal sensor can be installed up to 200 feet from the controller using 1/4" O.D. tubing, provided the sensor is mounted horizontally with the bimetal facing up.

Can this unit be used for both heating and cooling?
Yes, the dual-pressure design (RA at 16 psig / DA at 25 psig) is specifically engineered for proportional heat or cool applications in unit ventilators and fan coil units.
