T460 Series (2298 Series)<br />
Unit Temperature Controllers<br />
The Unit Temperature Controllers are designed for<br />
the proportional control of pneumatic devices and<br />
actuators in environmental control systems. These<br />
devices are designed primarily as return air<br />
controllers in induction units, fan coil units, and<br />
unit ventilators.<br />
Features:<br />
• Small size.<br />
• Attractive appearance.<br />
• Stable, linear response to room temperature changes.<br />
• Sensor may be mounted up to 200 ft. (61 m) from<br />
controller; connects to controller body with 1/4 in. outside<br />
diameter (O.D.) polytube.<br />
• Summer-winter models have snap-acting changeover from<br />
direct action to reverse action and vice versa.<br />
