ABSTRACT:
The disclosure pertains to thermostats having an improved interface. In some cases, the present disclosure relates to thermostats that can display not only menu items, temperature set points and the like, but also has an ability to display variable textual information that is not predefined at the time of manufacture of the display. The thermostat may include an LCD display that is viewable from outside of the thermostat housing and that includes a first region and a second region. The first display region may include an array of fixed segment pixels that are arranged into a plurality of rows and a plurality of columns for displaying text in a dot matrix format. In some cases, the first region may be adapted to display messages, including scrolling messages. The second region may include a plurality of fixed segment graphical icons, which may be more precisely and more clearly displayed than if displayed using the array of fixed segment pixels of the first region.
