摘要: A controller for at least one damper maintains a constant volume rate of flow of air through a duct into a controlled space for a given condition in the controlled space. The dual reset controller resets the volume rate of flow as functions of two sensed conditions.

摘要: A controller for a damper maintains a substantially constant volumetric rate of flow of air through a duct into a controlled space for a given condition in the space and resets the rate of flow to three different levels as a function of three different conditions in the space. Two pneumatic actuators respond to the four conditions in the space and produce forces which vary with the conditions. A floating lever receives the forces and causes the controller to set the air flow as a function of the sum of the weighted values of the forces produced by the two actuators.
