Abstract
A system for controlling delivery of either heated or cooled water to a plurality of heat exchangers includes a system controller which gathers information as to the current and future heating or cooling demands of a plurality of zone controllers associated with the plurality of heat exchangers. The system controller analyzes current demands for heating or cooling in combination with future demands for heating or cooling to determine if there is any combination of current and future heating or cooling demands that exceed a minimum level or number of demands necessary to authorize heating or cooling. A start time for the provision of the heated or cooled water is thereafter determined by the system controller in the event that there is any combination of current and future heating or cooling demands that exceed the minimum level or number of demands necessary to authorize a heating or cooling.
