Abstract
An integrated zoning circulator includes a priority controller, integral with the zoning circulator, for determining the priority given to the circulator in an individual zone of a multi-zone hydronic system. The zoning circulator also includes a priority circulator system for a multi-zone hydronic system having a zoning circulator at each zone, a plurality of control boxes each having a thermostat, one control box being associated with each circulator, and, a plurality of priority controllers, one priority controller being associated with each control box. Each priority controller, when activated, functions to assure that when the associated thermostat calls for the circulator to operate, other circulators in non-priority mode are prevented from operating simultaneously.
