The Model 3000 provides two additional control wires between a thermostat and indoor unit, or indoor unit and outdoor unit.
Compatible with all 24VAC heating and cooling systems.
The Model 3000 can provide a common connection 'C' using a thermostat cable with 3 or more wires. For adding a common with only 2 wires see the Model 5000 or Common Maker.
Product is only to be installed by a qualified heating and cooling technician
This has saved my But multiple of times! I keep 2 of them on my Truck for just incase. If you only have 2 wires and need 4 or 5 this is the golden ticket! Don't want to pull a New 5 wire? Don't Use this instead! Very easy to install very good digram!

Great product
As a HVAC Technician/Installer. This is a life saver. When you only have 2 wires and need 4 or 5 this is great. Had no issues with it.
