KMC Controls CTC-1622-103 Stat

The KMC Controls CTC-1622-103 is a high-performance 2-pipe pneumatic thermostat engineered for precise temperature regulation in commercial HVAC systems. This reverse-acting room thermostat features a highly sensitive bimetal element and a pilot relay to ensure stable, proportional control of pneumatic valve and damper actuators. Designed for a 2x3 vertical mount, this unit operates efficiently within a 3 to 15 psi signal range and handles a maximum supply pressure of 30 psi. The field-adjustable throttling range allows for granular system tuning to match specific zone requirements. Contractors often utilize the CTC-1622-103 in pneumatic control systems requiring a 55 to 85 degree Fahrenheit setpoint range. Built with a rugged, flame-retardant plastic enclosure, this Tstat is compatible with standard mounting accessories like the HMO-5030 wallplate. Its energy-efficient proportional control logic reduces cycling, extending the lifespan of connected mechanical equipment in demanding industrial environments.

• Precision Control: Utilizes a pilot bleed relay for accurate, consistent feedback to pneumatic actuators.
• Durable Construction: Housed in a flame-retardant plastic enclosure for long-term reliability in utility and mechanical rooms.
• Adjustable Calibration: Features a factory-set throttling range that is easily field-adjustable for custom sequencing.
• Reduced Setpoint Drift: The integrated bimetal element provides rapid response to ambient temperature shifts.

Is this thermostat direct or reverse acting?
The CTC-1622-103 is a reverse-acting pneumatic thermostat, meaning the output pressure decreases as the sensed temperature rises.

What components are required for a full installation?
This base unit requires a scale plate assembly (vertical F) and a thermostat cover (2x3 window or blank), which can be ordered as a value package or separately.

Can I lock the setpoint on this model?
Yes, the setpoint sliders can be limited or locked using HFO-0027 setpoint stops to prevent unauthorized adjustments in public spaces.
