T9 Smart Programmable Touch-Screen Wi-Fi Thermostat with Smart Room Sensor (RCHT9610WFSW2003)

Honeywell Home's new T9 smart thermostat is a very powerful smart thermostat which works with smart room sensors to maintain the temperature in your home, any time of the year. The smart room sensors monitor the temperature and humidity, and connect to the T9 smart thermostat. You can operate the T9 either through its touchscreen, or through the Honeywell Home app, to set and monitor each room's temperature. The T9 smart thermostat comes with one sensor and a C-Wire adapter, which is for homes that do not have a C-Wire or common wire. For newbies, this wire is required to operate most new smart thermostats. How do you know if you have a C-Wire? Take off the cover of your existing thermostat, and see how many wires are connected to your existing thermostat. In most older homes, you will find only two wires. If this is what you see, then you will need to either get an electrician to install a C-Wire, or you can use the C-Wire adapter that comes with the T9.
