Meet the White Rodgers 1 Pole 2 Throw 24 V Fan Relays — a compact, enclosed relay designed to deliver precise, dependable fan control in HVAC systems. Built for standard 24 V control circuits, this SPDT (single pole, double throw) device simplifies how you switch fans, blowers, or auxiliary fans in furnaces, air handlers, and other HVAC equipment.
Key benefits that set this relay apart
-
1 Pole 2 Throw (SPDT) configuration for versatile control. Use the common terminal to feed two separate outputs, enabling two-stage fan control, alternate circuit paths, or quick changeover between loads without adding complexity.
-
24 V coil rating tuned for compatibility with standard thermostats, control boards, and low-voltage wiring in most homes and light commercial systems.
-
Enclosed design provides a robust, dust-resistant housing that protects wiring and terminals, streamlining installation and maintenance in challenging environments.
-
Safety and compliance with UL Listed and CSA Listed certifications, helping you meet code requirements and giving you peace of mind during inspections.
-
Solid temperature capability with a maximum temperature rating of 150, ensuring reliable operation across typical HVAC environments and room conditions.
-
Compact, dependable construction designed for straightforward mounting inside control panels or near the HVAC equipment it serves, reducing clutter and simplifying wiring.
Ideal use cases
Designed for practical, real-world HVAC scenarios, this White Rodgers relay is a perfect fit for:
- Driving a blower motor in furnaces and air handlers from a 24 V thermostat or control board.
- Implementing two-stage or alternate-load fan configurations where a single relay handles two outputs.
- Isolating control circuitry from higher-power fan circuits, offering safer wiring and easier troubleshooting.
Why choose this relay over alternatives
Compared to open-frame or non-enclosed relays, the White Rodgers 1P2T 24 V Fan Relay provides a safer, tidier solution with a sealed housing that protects connections from dust and accidental contact. Its UL and CSA listings simplify code compliance, while the SPDT wiring offers flexible control options without adding hardware complexity. This combination makes it a reliable upgrade or replacement part for both residential and light commercial HVAC projects.
Practical installation tips
- Plan your control wiring so the 24 V coil is driven by a compatible thermostat or control board output. Coil polarity is not a concern for AC coils.
- Mount the relay in a dry, accessible area within the control panel to simplify future service and testing.
- Ensure connections are secure and terminals are tightened to prevent loose wiring and future arcing.
- Verify loads on each output to stay within any system limits and prevent overheating, taking into account startup current for the fan motor.
Whether you’re updating an aging HVAC control path, setting up a new air handling setup, or implementing a two-path fan control strategy, the White Rodgers 1 Pole 2 Throw 24 V Fan Relays deliver dependable performance, clean installation, and the confidence of code‑compliant safety certifications.
