Abstract
Heating, ventilating and air conditioning (HVAC) equipment units are provided with controllers which may be interconnected to a third or common controller, such as a communicating thermostat, and provide information in a process to determine if two or more of such air conditioning units may be operated as twinned units. Information is transmitted over a data bus between the controllers for the respective air conditioning units and the common controller to determine if the air conditioning units are the same type, of a same family and of essentially the same capacity before permitting twinned operation. If one of the air conditioning units is not twinnable, an alarm signal is generated to prevent operation of the air conditioning units in a multiple-unit configuration.
