In most cases, one thermostat is sufficient to control the temperature in the entire house. In some houses, however, it might be more desirable to divide the house into several areas or zones. Each zone would then be controlled by a separate thermostat. With systems such as electric cable or electric baseboard, zoning is easily achieved. With ducted or piped systems, special dampers or valves are usually needed. Such ducts and pipes must be specifically designed for zoned control. Zoning can be used to maintain slightly different temperatures in various areas of the house, but is most useful in maintaining even temperatures in rooms with varying sun and wind exposure. Zone control will also help save money on utility bills. In some cases, proper zoning can result in an operating cost savings of as much as thirty percent. Zoning, therefore, increases the overall efficiency of your air conditioning and heating system.
