Abstract:
1. In a ducted gas flow system having a network of ducts with code key terminals and balancing dampers in the terminals, the improvement comprising a wireless damper control system having: a plurality of motor driven damper units having a duct housing with a flow volume control mechanism, each of the damper units being installable in a terminal of the ducted network for control of the volume of gas flow in the terminal, the damper unit having in addition, a drive motor with a drive mechanism connecting the drive motor to the flow control mechanism, a receiver unit, an electronic circuit that operates the damper unit under direction of the receiver unit, and a power source powering the drive motor and receiver unit; a portable remote controller having a power source, input controls that select one of the plurality of damper units in the ducted gas flow system and input controls that operate the flow volume control mechanism of the selected damper unit to regulate the volume of gas flow in the terminal of the selected damper unit, wherein the volume of gas flow in each terminal is adjusted for a desired balance of gas flow in the ducted gas flow system by select adjustment of the volume control mechanism of each damper unit, and wherein the adjusted volume control mechanism of each damper unit is maintained in position after adjustment and balance of the system; and, a control box electronically connectable to a selected damper unit wherein the control box enables the flow volume control mechanism to be operated.
