A climate control system having a control head including a display providing at least one comfort level indicator and a fuel economy indicator is provided. The comfort level indicator displays a plurality of comfort level settings corresponding to relative thermal comfort in all weather conditions. Each comfort level setting corresponds to a range of temperatures so that once a comfort range is obtained, the climate control system will be reluctant to consume additional energy, thereby maintaining or improving the current fuel economy state. The fuel economy indicator provides for direct communication of the impact of comfort level settings on fuel economy.
