摘要：A zone control apparatus for central heating and/or cooling systems having acentral fluid heating and/or cooling plant conduits for directing the heated or cooledfluid to the rooms in a house or other building being serviced by the system. The zonecontrol apparatus comprises one or more flow control devices operatively withrespective fluid conduits in the central heating and/or cooling system, and a cyclecontroller for cycling the flow control device or devices between high and low (or no)flow conditions at times strategically selected to correspond to periods of high and lowuse of the room or rooms with which the flow control devices are respectively associated.Accordingly, the apparatus operates automatically to eliminate unnecessary heating orcooling of individual rooms or zones during cyclical periods of low or no use wherebysubstantial energy savings and other benefits may be obtained with minimal compromisein comfort. In particular, the zone control apparatus may operate on the system toisolate or separate daytime and nighttime use areas or zones of the house for selectiveheating or cooling only during their respective daytime or nighttime use or anticipateduse periods. Moreover, the zone control apparatus may be easily installed in existingsystems as a retrofit or in new installations.
