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.

Claims12

Dependent claims

An integrated zoning circulator associated with an individual zone of a hydronic heating or cooling system that includes a plurality of zones, each zone including a thermostat associated with the zoning circulator, the integrated zoning circulator comprising:

a wet-rotor circulator motor disposed within a motor housing, and;
a priority controller, for determining priority of operation for the integrated zoning circulator, said controller disposed within a controller housing integral with the motor housing said priority controller comprising:
a manual switch having a setting selectable by a user of the hydronic system for establishing the priority of operation for the zoning circulator relative to other zoning circulators in the system;
and
circuitry, connected to the zoning circulator and manual switch, adapted to operate the zoning circulator and to prevent simultaneous operation of zoning circulators in other zones that have manual switch settings of lower priority than the selected setting of the manual switch, when the thermostat, associated with the zone in which the integrated zoning circulator is disposed, calls for the zoning circulator in that zone to operate.

A priority circulator system comprising

a multi-zone hydronic system having a plurality of zones, an integrated zoning circulator associated with each zone, each zone having a thermostat associated with the zoning circulator and, each integrated zoning circulator comprising:
a wet-rotor circulator motor disposed within a motor housing, and;
a priority controller, disposed within a housing integrated with the motor housing controller said priority controller comprising
a manual switch having a setting selectable by a user of the hydronic system for establishing the priority of operation for the zoning circulator relative to other zoning circulators in the system;
and
circuitry, connected to the zoning circulator and manual switch, adapted to operate the zoning circulator and to prevent simultaneous operation of zoning circulators in other zones that have manual switch settings of lower priority than the selected setting of the manual switch, when the thermostat, associated with the zone in which the zoning circulator is disposed, calls for the zoning circulator in that zone to operate.
