This multi-purpose relay provides a dependable electrical switching solution for central heating, air conditioning, and ventilation equipment control setups. Utilizing an efficient 24VAC or 25VAC low-voltage coil, it functions seamlessly alongside standard mechanical and electronic room thermostats to route auxiliary power lines as required.
The double pole double throw (DPDT) contact arrangement makes this component incredibly versatile for custom field retrofits, control board replacements, or equipment upgrades. It enables service technicians to safely switch two independent circuits simultaneously, making it an excellent choice for managing dual-stage fans, dampers, and compressor staging signals.
Before performing a replacement or new installation, confirm that your system control transformer provides the correct 24-volt alternative current supply to actuate the internal relay coil. Its compact design allows for straightforward mounting inside standard electrical control cabinets or furnace burner compartments, helping restore automated operation efficiently.
