 With one thermostat the entire house is one zone, making it difficult to control the comfort level throughout the house.
 With multiple thermostats (zoning), occupants can maintain their desired temperature set point upstairs and downstairs independently of each other.
How the Ultra-Zone System Works
The purpose of the Ultra-Zone system is to provide total comfort in the home and office. Motorized dampers are "opened" or "closed" by thermostats based on the temperature set point of the homeowner. The damper system will control the airflow through the ductwork and deliver ONLY the desired air to the desired location. Each thermostat has the ability to turn on and shut off the heating and cooling. The Ultra-Zone system can accommodate over 30 zones. This means that over 30 thermostats can be installed in a home or building to control the temperature in each zone.
There are very few Ultra-Zone components that are needed to make the zoning system function. The control panel is the "brain" of the system. The zone thermostats allow independent temperature control and the zone dampers control the airflow to the zone thermostats. A transformer is needed to power the system and occasionally a by-pass damper may be required.
The basic components of an Ultra-Zone system are:
1) A Control Panel
2) Zone Thermostats
3) Zone Dampers
4) Dedicated Transformer
5) By-pass Damper
    (If necessary)
Along with some thermostat wire, these are the only components that are needed to install an Ultra-Zone system. The above diagram shows a typical installation with all of the components needed for a zoning system.
