Universal Twinning Kit

Our Universal Twinning Kit is like a party starter for your HVAC systems - it allows one thermostat to control up to four units, no sweat! You don't even need fancy wiring - just your everyday 18-gauge wire. And the fun doesn't end when the party moves to another room - you can keep having a good time up to 300 feet away. Plus, its aluminum backplate and mounting holes make setup a breeze. Get ready to rock it with a 24VAC input voltage and a 5-year warranty!
