ABSTRACT:
A temperature control system for an air conditioning system that services plural zones provides priority of one or more selected zones of the conditioned air flow relative to the other unselected zones. Priority is achieved by closing those dampers associated with the unselected zones to direct the conditioned air flow into the selected zones. The temperature control system also provides for fail-safe operation by utilizing dampers biased in the open position and by preventing all dampers from being closed at the same time when conditioned air is flowing.
