CTC-1621-103 Tstat: 2-pipe, DA, Vertical FSKU: CTC-1621-103
These two-pipe, single-setpoint thermostats provide proportional control of pneumatic valve and damper actuators in HVAC systems. A highly sensitive bimetal element and pilot relay provide stable, accurate feedback. Models are available with either direct or reverse proportional action. The throttling range is factory set and field adjustable. Setpoints are adjusted using sliders which can be locked or limited using setpoint stops (HFOâ 0027).
The thermostats require a scale plate assembly and cover! Cover and scale plate items may be ordered separately or in a value package (CTC-162X-1x3) that includes the most commonly ordered accessories. See the data sheet for a list of accessories.
