Programmable thermostat with rotary dial program setting
First Claim
1. A programmable thermostat for the control of the temperature of a medium within a space by utilizing a temperature-modifying device, said programmable thermostat comprising:
- (a) comparison means for comparing an existing temperature of said medium within said space to a temperature desired to be achieved of said medium in said space,(b) a programming means connected for generating a program to control a thermal output of said temperature-modifying device to achieve said desired temperature,(c) an input means connected for inputting information to said programming means,(d) a memory storage means connected for storing information received from said programming means,(e) a display means connected to said programming means for displaying information contained by said programming means, and(f) a rotatably settable controller connected for controlling said programming means, said controller comprising;
(i) a position for setting at least one weekday program,(ii) a position for setting at least one weekend program,(iii) a position for setting the current time, and(iv) a position for controlling said temperature-modifying device,wherein said programming means is connected to receive said information inputted into said input means and performs said function defined by said position of said controller.

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.
