+wire® provides reliable power for smart WIFI thermostats


+wire adapter
The +wire® product enables installation of a smart thermostat (such as Nest® or Ecobee®) in single-family, multi-family, and mobile homes where there is no common-wire available at the thermostat location of the building. Unlike other products, the +wire® requires only two wires in the wall. All other adapters require at least three wires to operate. The +wire® enables a smart thermostat to control heat-only HVAC systems with only a red and white wire. The +wire® can add a fan-only function to heat-only HVAC systems.
Features:
- +wire® adaptor works on any HVAC system with 2 or more wires
- +wire® common wire adaptor is sealed with shrink tubing which produces no Volatile Organic Compounds (VOCs)
- Small size, no mechanical mounting is required for faster installation
- Flexible wires allow easy installation at the thermostat and the HVAC system
- +wire® can also be used to replace a non-functional wire in the wall
- Made in USA
- 5 year warranty
- US Patent 10921014
+wire adapter with transformer
The +wire® with transformer has all the features of the +wire® adapter 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.
