* Requires “C”‐wire HVAC connection or 24v transformer for Wi‐Fi functionality
24V 300MA transformer for any thermostat where the "C" terminal is not powered
Which option is right for me?
* What is a “c-wire”?: Newer thermostats that offer clocks, backlit displays, wireless access, etc. are controlled using circuit boards and integrated circuits. These new circuits require a path to neutral, and so require an extra wire. This new wire runs from the furnace/HVAC unit to the thermostat and is known as the “C-wire”, or common wire.
* How do I know if I have a c-wire connected?: You can test for a c-wire connection by removing the batteries from your existing thermostat and seeing if thermostat stays on or powers off. If the thermostat stays on, then you have a c-wire connection, but if it powers off, then you do not have a connected c-wire. If your thermostat is not digital and does not require batteries, then it is likely an older mercury switch thermostat and is not connected to a c-wire.
* What are my options if I don’t have a c-wire connected?: If you do not have a c-wire connected, you can see if there is an unused wire in the cable that runs between your furnace/HVAC unit to your thermostat, and you can use that wire as a c-wire. However, it is recommended that you consult a professional electrician/HVAC technician to ensure that the wire is properly connected on both ends of your system. Otherwise, you can use the optional 24v transformer and plug it in to a standard wall outlet.

In a few minutes, I knocked off hundreds of dollars each year from my power bill.
All it took was swapping out our old thermostat with a new wireless radio thermostat so that I could better control the air conditioning at home from anywhere.
This is the smartest energy/money saving makeover we’ve ever done. My power bill has dropped so dramatically that it more than paid for the new radio thermostat in the first month. EPA estimates that you can see an average of 33% savings.
What makes it a winner? Tap into the thermostat online or by smart phone to control it from anywhere in the world. I set it higher during the day while away from home in summer months, and then tap on the app to get my house nice and chilly when I am starting to head back to the house. It works just the same in the winter to save on heating.
I know this sounds lazy, but I’m just being real. We end up adjusting the a/c from bed now on our iPad and phone, too. I don’t like this, I LOVE this way of saving money and making life easier.Plus: This does not require subscription unlike some of the earlier competitors. This CT30 Radio Thermostat is the clear winner.
Tip: If you are not as much a DIY soul, then it makes sense to buy now and have the A/C rep put it in on the annual or next visit.
