1. Apparatus for controlling temperature in a plurality of zones in a building, the apparatus comprising:

  • a heat exchange means,a plurality of mutually isolated heat exchange paths extending through the heat exchange means and terminating in respective outlet ports for accommodating flow air therethrough for delivery to the respective zones,a plurality of mutually isolated bypass paths corresponding to the respective heat exchange paths and terminating in the respective outlet ports for accommodating the flow air to bypass the corresponding respective heat exchange paths to the corresponding respective outlet ports,a plurality of inlet ports for accommodating return air therethrough returned from the respective zones,a plurality of return air temperature sensing means for sensing the temperature of the return air from the respective zones,a plurality of primary valve means corresponding to the respective heat exchange paths, each primary valve means being selectively operable in response to the temperature of return air from the corresponding one of the respective zones in one of a first state for directing the flow air through the corresponding heat exchange path and a second state for directing the flow air through the corresponding bypass path, andan air circulating means for circulating air through the apparatus from the inlet ports to the outlet ports thereof.
