Cleveland Controls NS2-0000-00 Switch

The Cleveland Controls NS2-0000-00 is an essential field adjustable air pressure sensing switch designed for high-accuracy airflow proving in residential and light commercial HVAC systems. This universal kit serves as the direct replacement for S1-024-19110-701, offering technicians a versatile solution for differential pressure monitoring. Built with a rugged glass-filled polycarbonate housing and a high-grade silicone diaphragm, the NS2-0000-00 provides a reliable set point range of 0.10" w.c. to 10.0" w.c. The SPDT switch action and 90-degree quick-connect terminals ensure seamless integration into existing control circuits, while the included color-coded springs and mounting hardware allow for precise calibration to specific furnace draft or static pressure requirements. This HVAC pressure switch is engineered to withstand demanding environments, featuring an operating temperature range of -40°F to 190°F and a maximum pressure rating of 14" w.c., ensuring long-term combustion safety interlock performance.

• Universal Compatibility: Specifically engineered as the direct replacement for S1-024-19110-701, simplifying inventory for service contractors.
• Wide Adjustment Range: Field adjustable from 0.10" to 10.0" w.c. using the included 7/32" hex wrench and specialized range springs.
• Extreme Durability: The corrosion-resistant silicone diaphragm and polycarbonate body ensure reliable performance over 100,000 cycles.
• Comprehensive Installation Kit: Includes mounting brackets, orifice plugs, and calibration springs for immediate field deployment.
• Versatile Sensing: Capable of monitoring positive, negative, or differential pressure to verify inducer motor and venting integrity.

How do I calibrate the set point on the NS2-0000-00?
Technicians should select the appropriate color-coded spring for the desired range, install it into the center well, and use the hex wrench to adjust the set point screw while monitoring with a digital manometer for precise trip point verification.

Can this switch be used to replace fixed-setting OEM switches?
Yes, the NS2-0000-00 is designed as a universal air pressure switch kit. It is often used by contractors to replace fixed-calibration switches in the field when the exact OEM part is unavailable, provided the set point is calibrated correctly.

What causes a "Pressure Switch Open" fault code in a furnace?
Common issues include blocked flue pipes, cracked pressure tubing, or a failed inducer motor. If the inducer is pulling sufficient vacuum but the switch contacts fail to close, the NS2-0000-00 provides a high-reliability replacement to restore safety circuit continuity.
