ABSTRACT:
A temperature control device is provided which comprises a thermostatic control means. The thermostatic control means is for automatically controlling the temperature of a location to a predetermined temperature. A means is additionally provided for setting the predetermined temperature. The means for setting includes an elongated temperature scale and a set point. The scale and set point are movable with respect to each other. The set point indicates the predetermined temperature on the scale.
The scale has associated therewith different colors along the periphery thereof. A means for illuminating the temperature scale near the set point is provided to reveal the color associated with the predetermined temperature. Thus an observer of the temperature control device, knowing the colors associated with the temperatures or knowing the colors at which he is most comfortable, can immediately observe from a distance the predetermined temperature at which the device is set. The device is particularly useful for those with impaired vision who cannot readily observe the numbers on the temperature scale.
