User interface for special purpose controller
A temperature controller for controlling the temperature of an inside space that is serviced by one or more pieces of HVAC equipment. The temperature controller may include a controller having a control algorithm for controlling one or more pieces of HVAC equipment as well as a user interface that may be configured to display a hierarchical menu structure and to permit a user to traverse the menu structure. The user interface may be configured to display breadcrumbs that provide an indication to the user of the current location within a hierarchical menu structure, and in some cases, provide instructional information in a designated or common display area that helps instruct the user in using a particular menu or menu option. These and other features may help make the special purpose controller more intuitive to set up, program and operate.
