1. An apparatus for thermal conditioning, said apparatus comprising:

  • means for generating a desired thermal condition, said desired thermal condition being conveyed to a plurality of predetermined locations by a thermal distribution medium, said plurality of predetermined locations including a corresponding plurality of heat exchange devices for receiving said thermal distribution medium and a corresponding plurality of thermostats for indicating a chosen thermal condition and a prevailing thermal condition;

    means, coupled to said plurality of thermostats, for storing a plurality of thermal conditioning requests, each of said thermal conditioning requests being produced when said prevailing thermal condition is inconsistent with said chosen thermal condition;

    means, coupled to said storing means, for selecting one of said plurality of thermal conditioning requests to establish a selected conditioning request;

    means for comparing the temperature of said thermal distribution medium with a target range to establish a thermal modulation flag when said temperature of said thermal distribution medium is outside said target range, and a thermal verification flag when said temperature of said thermal distribution medium is within said target range;

    means for adjusting said generating means in response to said thermal modulation flag produced by said comparing means; and

    means for executing said selected conditioning request in response to said thermal verification flag produced by said comparing means.
