+wire® Adapter with Transformer

*If using a credit card, the price of product includes a 3% credit card processing fee* 

The +wire® with transformer has all the features of the +wire® adapter -which enables easy installation of smart thermostats in homes without a common wire, using just two wires for heat-only HVAC systems and adding fan-only functionality - and includes a 24VAC transformer to allow the use of a smart thermostat (such as Nest® or Ecobee®) on millivolt gas fireplaces or furnaces. The transformer is installed at the heating element, and no extra wires are connected to the smart thermostat. The +wire® eliminates unsightly power wires from a transformer up the wall to the thermostat.
