摘要
A signal processor receives signaling containing information about flow rates from sensorless converters in zone circulators in heating/cooling zones controlled by temperature sensors in a hydronic heating system in order to derive an adaptive pressure set point to meet the flow rates requested by the heating/cooling zones using an adaptive system and flow control curve equation, the signaling containing information about total flow rates requested by the zone circulators; determines desired pump speeds for the zone circulators to meet temperature requirements in heat zones; provides corresponding signaling containing information about the desired pump speeds; and/or determines the adaptive pump control curve equation based upon an adaptive system curve and as a moving maximum system flow rate depending on an adaptive pressure set point, a system flow rate requested by temperature loads, a minimum pressure at no flow, a control curve setting parameter, and an adaptive moving maximum flow and pressure.
