In the heating and air conditioning world zoning referrers to adding conditioned air to only specific areas of the house.
Most homes have one thermostat on the ground level of the home. The thermostat takes a temperature reading of the air from the wall it is mounted on and determines whether or not the whole home needs heating or cooling. This works out ok for homes that are small and only have one level, but it does work for multi level, split level, etc. homes. In most homes you can walk around from room to room, floor to floor and notice a wide range of temperatures. It is common to have a two story home where the second floor is hot, basement is cold, and the first floor is at the desired temperature. How does the thermostat on the first floor know what the temperature on other floors and other rooms is? It doesn’t.
Some homes are zoned by using multiple, smaller heating and air conditioning systems through out the house. This works fine but can be very expensive. A more cost effective way to zone the house is with the use of multiple thermostats and motorized dampers in the ductwork. You put thermostats in each zone (example one on the first floor, second floor and basement) and when one thermostat calls for heating or cooling it sends a signal to a zone panel, the zone panel turns the heating or cooling, closes the dampers to each zone that is not asking for heating or cooling and only conditions the zone that is asking heating or cooling.
Zoning keeps your home at a more even temperature and saves you $$ by only conditioning the areas of the home that need it.
