ABSTRACT:
The invention is directed towards a programmable thermostat which includes a programming device for generating programs and a temperature comparison device to operate a temperature-modifying device, such as a furnace or air-conditioning system. This programming device may include a microprocessor which is capable of generating at least one weekday program and weekend program. The programming device of the present invention is also capable of generating a signal indicative of at least the current time of day, which signal can be used by the programming device in establishing its programs. The present invention also includes a rotatable, settable controller which controls the operation of the programming device. The rotatable controller includes a position for setting at least one weekday program, setting at least one weekend program, setting the current time, and controlling the temperature-modifying device. Additionally, the thermostat of the present invention may include an outer casing which has a door pivotably attached thereto which covers the rotatable controller. This door has protrusions on its inner surface which are arranged to prevent the door from closing unless the rotatable controller is set to operate the thermostat.
