Cleveland Controls NS2-0000-01 Switch

The Cleveland Controls NS2-0000-01 is a versatile differential pressure switch engineered for sensing air flow in HVAC and energy management applications. This field adjustable switch features a sensing range of 0.10" w.c. to 10.0" w.c., allowing technicians to calibrate set points with precision using the included calibration springs. Designed with a built-in bleed hole, it ensures reliable pressure stabilization and prevents cycling issues in sensitive furnace draft inducer systems. As a heavy-duty universal air pressure switch, it includes a robust mounting bracket and is designed to monitor positive, negative, or differential pressure. This unit serves as the direct replacement for 1170925, 1170926, and 1170924, making it a critical component for restoring system interlock circuits. Its narrow operating deadband and high-reactivity diaphragm provide the accuracy required for modern high-efficiency HVAC systems and industrial ventilation monitoring.

• Universal Compatibility: Engineered as a drop-in replacement for part numbers 1170925, 1170926, and 1170924 to streamline truck stock.
• Field Adjustable Range: Wide 0.1" to 10.0" w.c. set point flexibility accommodates various static pressure requirements.
• Enhanced Reliability: The integrated bleed hole aids in pressure equalization and prevents false trips in cooling or heating cycles.
• Complete Installation Kit: Ships with necessary mounting hardware and various springs for immediate field calibration.
• Industrial Grade Build: Proven Cleveland Controls diaphragm technology ensures long-term performance under high-cycle demand.

How do I adjust the set point on the NS2-0000-01?
Remove the cover and utilize the provided color-coded springs to reach your target pressure range. Use a calibrated manometer to verify the switch closes at the specific inches of water column required by the OEM equipment specifications.

Can this switch be used for both positive and negative pressure applications?
Yes, the dual-port design allows for monitoring positive pressure, vacuum (negative pressure), or the differential between two points in the air stream.

Is the bleed hole necessary for all installations?
The bleed hole is critical in specific draft inducer applications to ensure the switch resets properly when the blower de-energizes, preventing lockout codes in the control board.
