Abstract

An HVAC system includes a portable controller unit which communicates with an indoor HVAC component and an outdoor HVAC component over a digital communication bus. A multiple of docking stations each in communication with the data bus are located at a multiple of locations throughout the system such that the portable controller unit may be selectively connected to any of the ports and moved therebetween. By moving the portable controller unit, the technician is then physically present at the HVAC component while exercising the system to obtain additional information and measurements directly from the HVAC component.
