Cleveland Controls NS2-1227-02 Pressure Switch
The Cleveland Controls NS2-1227-02 Pressure Switch is a high-performance OEM replacement airflow sensor engineered for precise monitoring of positive, negative, or differential air pressure in HVAC induction systems and furnace draft control. This NS2 series air pressure switch features a durable, glass-filled polycarbonate housing that ensures thermal stability and contaminant-free operation in demanding commercial and residential environments. Designed for differential pressure sensing, this unit utilizes an integral snap-acting switch to confirm proper blower operation and flue gas venting before ignition.
For veteran technicians, the NS2-1227-02 offers versatile 90-degree quick-connect terminals and dual-barbed ports that accommodate 3/16" or 1/4" ID tubing. This component is a critical furnace safety switch that prevents operation under hazardous venting conditions. Its narrow switching differential and low setpoint tolerance make it a reliable choice for maintaining system integrity. When replacing a Cleveland Controls air switch, verify the specific WC (water column) setpoint and port configuration to ensure a direct match for your specific boiler or furnace model.
Key Benefits- High-Accuracy Sensing: Provides reliable electrical switching at low pressure thresholds for optimal system safety.
- Industrial-Grade Construction: Glass-filled polycarbonate body resists deformation under varying temperature ranges.
- Streamlined Installation: Color-coded ports (Black for Positive, Gray for Negative) facilitate error-free hose routing.
- Universal Terminal Connections: Male 90° quick-connect terminals simplify wiring in tight burner compartments.
Is the setpoint adjustable on this pressure switch?
The NS2-1227-02 is a factory-calibrated, non-adjustable switch. Setpoints are sealed to maintain precise OEM specifications for heating safety circuits.
What does it mean if my furnace is stuck on a pressure switch error?
This typically indicates a blockage in the venting, a failing inducer motor, or a cracked diaphragm within the pressure switch itself, preventing it from closing the circuit.
Can this switch sense vacuum as well as pressure?
Yes, the NS2 series is designed to monitor positive, negative (vacuum), or differential air pressure depending on the port configuration used.
