We know from years of feedback from readers, customers and amazon sellers, what most people want in a convenient and appropriate adapter. The venstar nest common wire adapter is exactly that - it's a simple adapter that hits all the right notes. It is way easier and hundreds of dollars cheaper than running a whole new wiring setup. It needs to be installed on the furnace side of the low voltage wiring. It allows the fan to run when the heat/cool process is happening. It is easy to install and costs very little compared to the alternative of pulling a new wire through the wall. It will work with any unit needing the additional power wire.

If you have a 4 wire system, this should allow you to add a common wire. It is perfect for nest thermostat, and excellent youtube instructional video. This works great if you are short of a wire on a furnace replacement.
