Abstract
A variable volume air conditioning system of the type having a duct for distributing air to a room, a damper for regulating the flow of air through the duct, and a damper actuator responsive to damper drive control signals for controlling the damper. A thermostat located in the room provides a stat signal representative of a desired flow of air through the duct. An actual flow signal representative of the actual flow of air through the duct is provided by a sensor. The stat signal and actual flow signal are compared by a comparator which provides the damper drive control signals as a function of the comparison. A wire transmission line couples the actual flow signal from the sensor to the thermostat so that service personnel can easily monitor system performance.
