Editorial Review

Radio Thermostat Company of America has been around for three decades, and has since introduced the CT80, a 7-day programmable and wi-fi enabled thermostat. It features a readable touchscreen display and works with almost all HVAC systems. True Auto mode switches between heat and cool, depending on conditions. Temperature and humidity sensors operate with 3 stages of heat and 2 of cool, and the thermostat can control the external air baffle, humidifier, and de-humidifier. The CT80 uses geolocation to save energy when you leave the home and prepare it for your arrival. It comes with Runtime Reports, temperature alerts, and on-board filter replacement and compressor protection notifications. It connects all your places with one app, be it another thermostat upstairs or one across town. You can share or remove control of each thermostat with family and guests while Radius synchronizes multiple smartphone geolocations. Feedback displays potential savings as well as outside temperature. This unit includes a WiFi unsnap module and a built-in battery backup.

Smart and connected homes are a subset of the Internet of Things, which are made up of millions of sensors that are embedded in appliances and other devices. These home products collect their own data, then share it with the others if necessary, and also feed it into a central system for analysis. With the resulting information manufacturers can alert customers about equipment or systems problems and how to fix them. Smart thermostats are one such device, and they are part of a vast global market. The demand for them is currently driven by North America, with 70% of the market share.

This means that the smart home is becoming mainstream. Perhaps this is due to the desire to feel smarter -- without actually having to do much to achieve it -- which a consumer feels after having gotten something with the smart prefix attached to it. However, judging from the installation and programming requirements for some smart things, if you weren't smart before you installed it, you're bound to be smarter afterwards. Why not try out the Ecobee Smart Si, which is from an industry leader, or the Starck Netatmo? Then again, the Lennox iComfort is no slouch either.

CT80 Reviews From Around The Web


The CT-80 has geofencing, which uses your smartphone's location to adjust your home's temperature when you come and go.

Tom's Guide

The unit itself is of good quality...touch screen works fine...can connect directly to the thermostat via the API whether you've registered with or not.

Tom's Guide

The software interfaces are easy to use...controls are pretty straight forward...will not keep on-board stats.
