Abstract
This invention relates to an electronic flow control circuit for use in the low voltage section of an existing control arrangement of a hydronic heating system that utilizes motorized zone valves, to provide a means for controlling fluid flow through the system in order to eliminate hydrostatic shock (water hammer) associated with fast closing motorized zone valves.
