KMC CTC-1653, 1654 Two/Three-Pipe, Two Temperature Pneumatic Room Thermostats with Local Indexing

Previous Page

The KMC CTC-1653 and 1654 thermostats provide proportional control of pneumatic valve and damper actuators in two-temperature (day/night, summer/winter) HVAC systems. Two highly sensitive bimetal elements, with feedback, and a pilot bleed relay provide stability and accuracy.

The CTC-1640's remote indexing is provided by dual main air supply levels. Local indexing is through push-button control. The first temperature control occurs when the main air supply pressure is 16 psig. The second temperature control is selected when the main air pressure is 25 psig. When 25 psig is supplied the local push-buttons allow switching between 16 psig and 25 psig modes.

Models are available in either direct or reverse proportional action. The CTC's throttling range is factory set and field adjustable.

Adjustable setpoints can be locked or limited using setpoint stops ( HFO-0027). A variety of optional scale plates and covers are available for both models.
