Advanced starting control for multiple zone system

Abstract

A system and method for controlling delivery of conditioned water to a plurality of heat exchangers includes a system controller which gathers information as to the current and future demands for conditioned water by a plurality of zone controllers associated with the plurality of heat exchangers. The system controller is operative to provide conditioned water to the heat exchangers even though current demands for conditioned water may not be sufficient to require the provision of conditioned water to the heat exchangers. The system controller analyzes current demands for conditioned water in combination with future demands for conditioned water to determine if the combined demands exceed a minimum level or number of demands necessary to authorize provision of conditioned water to the heat exchanger. A start time for the provision of the conditioned water is thereafter determined by the system controller in the event that any combination of current and future demands for conditioned water exceeds the minimum level or number of demands necessary to authorize a provision of conditioned water.
