KMC Controls CTC-1611 Thermostat

The KMC Controls CTC-1611 is a high-performance, one-pipe pneumatic thermostat engineered for precise proportional control of HVAC pneumatic valve and damper actuators. As the direct updated replacement for the CTE-5001-10 and CTC-1001-10, this direct-acting (D.A.) unit utilizes a highly sensitive bimetal element with feedback to ensure stable room temperature regulation. Designed for rugged commercial environments, it features a flame-retardant plastic construction and supports a setpoint range of 55?? to 85?? F. The CTC-1611 operates at a maximum pressure of 30 PSI and requires an external 14.4 scim restrictor (such as the HFO-0010) in the supply line for proper pneumatic room thermostat operation. Field technicians can easily adjust the factory-set 3??F throttling range up to 12??F to match specific environmental demands, while the slider-based setpoint adjustment can be locked or limited using optional stops to prevent unauthorized tampering in public spaces.

• Universal Compatibility: Seamlessly replaces legacy KMC Controls models including the CTE-5001-10 and CTC-1001-10.
• Enhanced Stability: The integrated bimetal element with feedback provides accurate response times and prevents hunting in proportional control loops.
• Field Adjustability: Features a field-adjustable throttling range (3?? to 12?? F) to fine-tune system sensitivity.
• Flexible Mounting: Designed for easy installation in standard 2 x 4 inch electrical boxes or directly onto hollow walls.

Is the CTC-1611 a direct replacement for the CTC-1001-10?
Yes, the CTC-1611 is the official updated version for both the CTE-5001-10 and CTC-1001-10, maintaining the same direct-acting logic and single-pipe configuration.

What air supply requirements are necessary for this thermostat?
This 1-pipe pneumatic thermostat requires clean, dry control air at a nominal 20 psig, with a maximum limit of 30 psig. An external 14.4 scim restrictor must be installed in the supply line.

Can the setpoint be locked to prevent occupant adjustment?
The unit is equipped with sliders that can be concealed or secured using setpoint stops (HFO-0027) to lock or limit the adjustment range by the end-user.
