Cleveland Controls DDP-106-214 Switch

The Cleveland Controls DDP-106-214 is a professional-grade Dual Air Pressure Sensing Switch engineered for high-precision monitoring in HVAC and Energy Management systems. Built with a twin-housing configuration, this 2-SPDT air flow switch provides dual switching action via two independently adjustable snap-acting switches mounted on a single common foot bracket. This setup allows technicians to establish a precise adjustable deadband or monitor separate pressure differentials within a range of 0.05" to 2.0" w.c. with an exceptional repeatability of ±2%.

Designed for versatile field integration, the DDP-106-214 features 1/2" NPT conduit openings and 90-degree quick-connect terminals to streamline electrical contractor installation. The three sample line connections utilize 1/4" OD compression ferrule and nut fittings, accepting rigid metallic or semi-rigid tubing. This proving switch is rated for 120-277 VAC and is ideally suited for air flow failure detection, damper positioning, and filter monitoring where reliable electrical switching at specific set points is critical for system safety.

• Independent Set Points: Two separate SPDT switches allow for unique high and low actuation points on a single assembly.
• Precision Range: Highly sensitive adjustment from 0.05" to 2.0" w.c. covers most standard commercial venting and fan proving needs.
• Robust Construction: Plated housings and high-quality diaphragms ensure 100,000+ cycles even at 0.5 PSI maximum pressure.
• Universal Mount: Common foot bracket design with 7-inch spacing for easy surface mounting in vertical orientations.
• Flexible Connectivity: Compatible with 1/4" OD copper, aluminum, or plastic tubing for various industrial environments.

How do I adjust the differential set points on this switch?
Use the adjustment screws on each element; one full turn equals approximately 0.2" w.c. It is recommended to use a digital manometer during calibration to verify precise actuation points.

What is the proper mounting orientation for the DDP-106-214?
The unit must be mounted with the diaphragms in a vertical plane. Avoid mounting with sample line connections facing upward to prevent moisture or debris accumulation from affecting the sensors.

Can this be used for both positive and negative pressure applications?
Yes. The high (H) and low (L) pressure ports allow for monitoring positive, negative, or differential pressure by varying the hose connections to the sampling probes.
