The Johnson Controls S-2300-2 Selector Switch is a professional-grade 5-port pneumatic selector switch engineered for manual air flow management within complex building automation systems. Built to handle a maximum input pressure of 30 psig, this unit features a robust 1000 scim flow capacity, making it ideal for multi-zone HVAC applications that require precise control over pneumatic actuators and sensors. As a core component for pneumatic control systems, the S-2300-2 facilitates two pairs switching with one exhausting port, ensuring seamless transitions between different operating modes without line pressure build-up. Its universal design allows for flexible panel or wallbox mounting, integrating easily into existing control galleries. The pre-installed barbed fittings for 1/4" OD polytubing provide a secure, leak-resistant connection, essential for maintaining system calibration and long-term HVAC pneumatic switch reliability in high-demand environments. For technicians upgrading or repairing vintage manifolds, this switch serves as a high-performance manual pneumatic controller that simplifies air logic routing. Key Benefits Field-Programmable Versatility: Can be configured for 2, 3, or 4-position switching using the included stop pin to meet specific layout requirements. High Flow Performance: Delivers a 1000 scim capacity to ensure rapid response times for downstream pneumatic devices. Integrated Exhausting: Features a dedicated exhaust port to prevent air trapping and ensure accurate signal pressure transitions. Complete Setup: Includes a four-window switchplate and a comprehensive set of self-adhesive service labels for clear field identification. Secure Connections: Factory-equipped with durable barbed fittings designed specifically for standard 1/4-inch OD polytubing. Common Questions How do you program the number of positions on the S-2300-2? The switch is field-programmable by using the provided stop pin and window blanks. Technicians can set the rotation to stop at two, three, or four positions depending on the system sequence needed. What is the maximum operating pressure for this switch? This model is rated for a maximum input of 30 psig, which covers most standard low-pressure pneumatic control applications in commercial HVAC units. Can this switch be used to replace other S-2300 series models? While the S-2300-2 has a specific port configuration (one exhausting, two pairs switching), it shares the same physical footprint as other S-2300 models. Always verify your specific air logic requirements before substituting models. Disclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
