Cleveland Controls DDP-106-292 Switch

The Cleveland Controls DDP-106-292 is a professional-grade air pressure sensing switch specifically engineered for HVAC and energy management systems requiring precise, dual-point monitoring. This robust proving switch features two independently adjustable SPDT snap-acting switches mounted on a single foot bracket, allowing technicians to establish a dedicated deadband for complex control circuits. With a setpoint range of .05" ± .02" to 2.0" w.c., the DDP-106-292 offers superior flexibility for sensing differential pressure in air or non-corrosive combustion by-products. The dual SPDT contacts are factory-configured to change on decreasing pressure at .20" w.c. and increasing pressure at 1.40" w.c., providing reliable performance for 120V to 277Vac applications. Built to handle a maximum pressure of 1/2 PSI, the silicone diaphragm ensures long-term stability without degradation from standard airborne particulates. Its three-port design—featuring one common high-pressure inlet and two separate low-pressure connections—accepts 1/4" OD metallic tubing for secure differential pressure switch installation.

• Independent Adjustment: Two separate sensing elements allow for fine-tuned control of high and low actuation points within a single HVAC pressure switch assembly.
• Wide Voltage Compatibility: Rated for operation across 120V, 208V, 240V, and 277Vac circuits, ensuring versatility for commercial and industrial proving switch applications.
• Durable Construction: Optimized for longevity with a 100,000-cycle minimum life at maximum rated electrical loads.
• Reliable Media Sensing: Designed for air and combustion by-products that are compatible with silicone diaphragm materials.

How do I adjust the setpoints on the DDP-106-292?
Each of the two SPDT elements features its own calibration screw. Turning the screw counter-clockwise decreases the pressure setting, while clockwise increases it, allowing for precise field adjustment within the .05" to 2.0" w.c. range.

What is the proper mounting orientation for this sensing switch?
To maintain the specified accuracy at the lowest setpoints, the Cleveland Controls DDP-106-292 must be mounted with the diaphragms in a vertical plane. Avoid mounting with sample line connections facing upward to prevent moisture or debris accumulation.

Can this switch be used to monitor differential pressure across a filter?
Yes, by connecting the high-pressure port upstream and the low-pressure ports downstream of the filter, the dual-switch configuration can be used to trigger separate alert and shutdown thresholds as the filter loads.
