ABSTRACT:
This invention relates to a method and system for controlling a heating/air conditioning unit. More particularly, this invention relates to a control unit which detects the presence of one or more gases (e.g. CO, fuel, refrigerant or rador) produced by the heating/air conditioning unit and disables the heating/air conditioning unit if gases are present in undesired concentrations. In one embodiment of the present invention, the presence of multiple gases are detected and a separate indication for each gas is provided. An alternate embodiment of the present invention provides means for resetting the heating/air conditioning unit a selected number of times after the heating/air conditioning unit has been disabled due to the presence of a gas in undesired levels. An alternative embodiment of the present invention provides means for disabling the central heating/air conditioning unit based upon the activation of one or more smoke alarms. Further, the present invention provides means for detecting inefficient combustion or other inefficient operation of the heating or heating/air conditioning unit and indicating said inefficient operation to the user.
