ABSTRACT:
The present invention is a control range display for an electronic thermostat. A plurality of individually actuable display segments are disposed in a line. Each of these display segments represents a particular temperature. The control range of the electronic thermostat is displayed by actuating the display segments representing the upper and lower preselected temperatures and all display segments therebetween. In the preferred embodiment each of these display segments is a liquid crystal display device. The preferred embodiment enables indication of the present temperature by actuation of a single display segment representing that temperature upon selection of a normal mode and an indication of the control temperature range by actuating display segments in the manner noted above upon selection of a program mode. The preferred embodiment further includes a removable mask containing a temperature scale indicia marked in a preselected geared measurement which can be disposed beside the line of display segments of the display means, thereby indicating the particular temperature represented by each display segment in the preselected unit of measurement.
