Common Wire Adapter Kit
Add a wire to connect your thermostat to SmartZone or your equipment.
Most modern (especially WiFi) thermostats require a common wire to be connected but it is often difficult to run a new wire to the thermostat location.
If you only have 4 wires but need 5 or if you have 5 wires but need 6, this common wire “ADDER” will do the trick.
This “COMMON WIRE ADDER” is universally compatible and will work with any thermostat and any equipment/zoning system.

Most modern thermostats require a “common wire” but a lot of homes do not have enough conductors in the thermostat wire bundle. The COMMON WIRE ADAPTER KIT solves this problem by turning 3 wires into 4, 4 wires into 5 or 5 wires into 6. So, if you are upgrading to a modern thermostat but are short one wire, this is the answer.
