Zone control systems are energy-saving inventions. The system links multiple thermostats that are strategically placed in your home so that you can adjust the temperature to a level of comfort in each room. This is useful if your home has many rooms or if your home is a 
multilevel structure.
A zone control system is composed of multiple thermostats on each level of your home and in different areas, or zones, of your home. Most homes have two thermostats, but some larger homes can have up to six thermostats installed. The group of thermostats monitors the air temperature throughout the structure. They are linked to a main control panel so that you can adjust the temperature at a main switch. If you are closing off a section of your home because you are not using it, you can handle that with ease at the control panel by turning the unit off in that area. If you are reopening a section because family members are coming to visit, you can quickly adjust the temperature in that zone of your home at the control panel.
Why Do You Need a Zone Control System?
If your home is constructed as a multilevel structure, the heat rises and causes the top floor to be warmer than the downstairs areas. The zone control system will monitor the air temperature and help regulate it to a comfortable temperature. Cool air sinks so the lowest level of your home will often be the coolest area year round. The zone control system will help you maintain a comfortable temperature in this area as well.
Traditionally, the thermostat is located in a hallway in the center of the home. It is an accurate gauge of the air temperature, but it is limited in scope and function as it can only measure the air temperature in the location where the thermostat is mounted on the wall.
What are the Benefits?
The zone control system will reduce the overworking of your unit. You can save on your utility bill because you are not constantly adjusting the thermostat. Selecting a comfortable temperature for each area of the home will reduce the need for constant adjustments and not force the air conditioner or heater to “catch up†with the temperature changes. Family disputes will be resolved since you will no longer be cranking up the heat because someone is freezing downstairs while someone upstairs is complaining because they are “frying.†Family will become united once again.
