Abstract
A zoning circulator for circulating fluid within a zone in a hydronic heating or cooling system includes a zoning circulator controller including a speed regulating circuit for controlling the speed of a circulator motor. The circulator controller also includes an override circuit for operating the circulator at a high speed, high starting torque for several seconds to overcome frictional resistances between the moving parts of the motor and then tapers down to the speed established by the speed regulating circuit.
