ABSTRACT A programmable thermostat employs means for controlling the application of electrical power to first and second temperature modifying loads. A device displays first and second preselected temperatures associated with the first and second temperature modifying loads respectively, the device including an elongate area of energizable indicia corresponding to an associated linear temperature scale, whereby the first and second preselected temperatures are represented on the device by energizing the entire elongate energizable area between limits defined by the first and second preselected temperatures on the associated temperature scale. The elongate area of energizable indicia is a series of discrete energizable segments representing a particular temperature indicated on the associated temperature scale and the first and second preselected temperatures are displayed b energizing each of the segments corresponding to the location of the first and second preselected temperature values on the associated scale and each of the segments lying therebetween. The preferred thermostat includes a mechanism for sensing the ambient temperature, a clock for generating digital electrical signals representative of real time, and a display device for indicating selected information.
