One light switch for the whole house -- sound ridiculous??? Yet most houses have only one thermostat! The Solution is … Zoning!
It provides area by area temperature control and Saves Energy!

If your house is like most, you probably have some rooms that are always much too hot, and others that are always much too cool.

Most buildings have a single thermostat, set at one temperature for the entire building.
Available for residential or commercial applications, zoning is individualized room temperature control that utilizes multiple thermostats and can be operated with your present heating/cooling system. It directs the heating or cooling only to the rooms you choose, and when controlled by programmable thermostats, energy savings in your home can be significant. Brochure
