Abstract
A thermostat comprising a circuit board for controlling the thermostat, a display, a keypad, and at least one electroluminescent element. The display is operatively connected to the circuit board for displaying information concerning the thermostat. The keypad has at least one key adapted to be pressed by a user. The key is operatively connected to the circuit board in a manner to enable the user to input at least one signal to the circuit board by pressing the key. The electroluminescent element is operatively connected to the circuit board and has a first electroluminescent section and a second electroluminescent section. The first electroluminescent section is adjacent the keypad and the second electroluminescent section is adjacent the display. The first electroluminescent section and the keypad are adapted so that the first electroluminescent section illuminates the keypad.
