1. A automatic balancing damper control system, comprising:
- a single set point environmental controller;
at least two temperature elements, each temperature element located in a separate zone and in communication with the environmental controller; and
a control output for a motorized damper, the damper responsive to the controller and configured to control a flow of air to the separate zones, wherein the controller is configured to accept temperature inputs from the at least two temperature elements and to send the control output for adjusting a position of the damper in accordance with the single set point and inputs from the at least two temperature elements.

Abstract
A control system for a heating, ventilating and air conditioning system is provided. The control system regulates a temperature of a multi-zone building using only a single thermostat or set point, and a temperature element in each of the zones. The control system receives inputs from the temperature elements and uses the inputs and a control algorithm to control temperature according to the set point and to minimize the differences between the temperature elements in the different zones. In a two-zone building, a single damper is used. In a building with a larger number of zones, the number of dampers required is the same as the number of zones, less one damper.

9. An automatic balancing damper control system for regulating temperature in at least two different zones, comprising:
-
a thermostat positioned in one of the two zones; a temperature sensor positioned in a different zone from the thermostat and in communication with the thermostat; and a motorized damper operatively connected to the thermostat, the damper positioned in fluid communication with temperature regulating appliance at an inlet and with each of the at least two different zones at outlets thereof; wherein the thermostat is configured to adjust a position of the damper in accordance with a single set point and temperature inputs from the at least two zones. - View Dependent Claims (10, 11, 12, 13)
