Venstar Nest Thermostat AC adapter

Buy on Amazon

Not everyone likes to purchase adapter for their daily usage, but the venstar nest thermostat ac adapter would be an anomoly. This unit is for a 4 wire system where you need to add a 5th wire for your thermostat. It can also be used for fixing a broken wire, to make one thermostat work like two, to add cooling to a heat-only system, or to add a common wire to a 4-wire system. This will work with any thermostat needing a C wire when there are only 4 wires present at the thermostat.

The units in the attic have a 'custom' wiring setup from the previous owners. It is easy to install, and works great if you get a used smart thermostat that doesn't include a power extending kit. These have the add-a-wire device in your hand, plus the photo of your panel, then watch the video. This is a must for reliable operation of nest 3rd gen if you don't have 'C' wire.

• Easy to install and worked with no problems
• Electrician to run wires, no bulky power adapter, no drywall cutouts and patches
• Easily upgrades old furnace to modern control
• Perfect solution to using a 5 wire thermostat when you only have 4 wires

Google Nest Thermostat AC adapter

Next on the list, we've got yet another adapter that manages to win our hearts. It's the google nest thermostat ac adapter and it's widely considered as one of the best convenient adapter you can buy. The Nest power connector is the nest thermostat c wire adaptor that is designed specifically for nest thermostats. It provides proper voltage and will help out many others. If you have a zoned system with more than one thermostat, the power connector should be installed at the zone controller. This kit really just avoids the need to run new wires, nothing else.

The power connector wires are about six to eight inches long. It takes several minutes for the heater or ac to come out and produce heat tor cold air. This product should come standard with the thermostat. If you need a control wire this device works great with the Nest products.

• Perfect team mate for nest thermostat and 2-wire systems
• Perfect solution for homes where the thermostat doesnt run the c wire
• Plugs into the panel "in" the furnace, not thru the walls
• Cheaper and faster than running an additional wire
