The one-pipe, single-setpoint KMC CTC-1611/1612 thermostats provide proportional control of pneumatic valve and damper actuators in HVAC systems. A highly sensitive bimetal element provides stable, accurate feedback.
Models are available in 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 (HFO-0027).
The thermostats require a scale plate assembly, cover, and an external 28.8 scim restrictor in the supply line (ordered separately). See the data sheet for a list of accessories.
