Abstract
A heating, ventilation and air conditioning (HVAC) system is provided. The system includes an integrated motor including a plurality of operating speeds and an input for selecting one of the plurality of operating speeds. The system further includes a system controller and an adjustment module. The adjustment module includes a plurality of operating modes each associated with one of the plurality of operating speeds and the ability to manually vary associations between the plurality of operating modes and the plurality of operating speeds. The adjustment module selects one of the plurality of operating modes on the basis of control commands received from the system controller and setting programmed or manually entered into and stored in the adjustment module and controls the integrated motor according to the operating speed associated with the selected operating mode.
