Abstract
A portable, preferably hand held control module for use in a heating, ventilating or cooling (HVAC) system that includes at least one subsystem that may be controlled via a service module which is located in proximity to that subsystem. The portable control module includes a plurality of manually operated keys for enabling a user to apply to the subsystem commands which are generally the same as commands which may be applied via the manually operable keys of the service module. The portable control module also includes a display assembly having one or more displays for displaying to the user information concerning the subsystem that is generally the same as that which is displayed on the display assembly of the service module. Finally the portable control module includes a coupling assembly which allows it to be detachably connected to the subsystem, or to a local area network (LEN) which services the subsystem, to enable the user to apply commands to and receive information from the subsystem without being in proximity to the service module.
