Product Overview:
Regulates room temperature in compatible unit ventilator systems through direct-acting temperature control. The Schneider Electric (Barber-Colman) 2298-061 Unit Ventilator Thermostat is designed to respond to changes in ambient temperature and support heating or cooling regulation within its specified 65°F–85°F operating range.
Temperature-Sensing Mechanism:
A remote bimetal sensing element responds to changes in return-air temperature and transfers the resulting thermal movement to the pneumatic control mechanism. This temperature-responsive action varies the branch air pressure to provide proportional control of connected pneumatic devices.
Pneumatic Control Operation:
The pneumatic control mechanism operates with a nominal main air pressure of 20 PSIG and a maximum pressure of 30 PSIG. A fixed 4°F throttling range governs the temperature interval for output modulation, while the 9 PSIG calibration point establishes the controller's specified calibration reference. A serrated thumb-wheel provides manual adjustment of the temperature setting.
Replacement Guidelines:
The Schneider Electric (Barber-Colman) 2298-061 Unit Ventilator Thermostat may require replacement if the existing unit is physically damaged or its essential temperature-control functions no longer operate as intended. Replacement may be appropriate when the thermostat cannot reliably regulate the unit ventilator according to the selected temperature setting.
Common Failure Symptoms:
- Inconsistent room temperature regulation.
- Unresponsive pneumatic output during temperature changes.
- Unstable temperature control around the selected setpoint.
- Connected pneumatic actuators failing to respond consistently.
- Inaccurate temperature regulation despite thermostat adjustment.
Equipment Compatibility:
Designed for use with compatible Schneider Electric (Barber-Colman) unit ventilator systems requiring direct-acting temperature control. The 2298-061 is intended for applications where space temperature regulation supports unit ventilator operation. Verify compatibility with the existing equipment model and control configuration before installation.
