The EBD (Electronic By-Pass) style are self-contained units that give you the static control mounted to the damper.

The model PRD pressure regulating damper is a single blade, steel, barometric damper with a counter balanced weighted arm.
​This damper is easy to install and easy to checkout. The LED display allows the installer to visually check the damper operation. With a sturdier frame, the damper installs in the duct much faster and easier and the nylon bushings insure quieter operation
Hand dampers are used to restrict airflow through the by-pass trunk during by-pass operation.
The control panel is a "brain" of the system, they control airflow to the zone thermostats. 
Thermostats allow independent temperature control.  They can be remotely controlled, wireless, Internet enabled or touch screen, digital and programmable.   
Ultrazone manufactures various accessories to make your life easier and your HVAC systems more efficient. Also most replacement parts are available.
