What is claimed is: 1. A programmable thermostat system for controlling space conditioning equipment comprising: A) at least one environmental condition sensor providing an electrical signal indicative of the ambient temperature of a conditioned space in which said environmental condition sensor is situated; B) a transparent touch pad juxtaposed with a liquid crystal display to constitute a touch screen for interactive interface with a user; C) a processor, said processor including: 1) a central processing unit; 2) a real time clock; 3) a memory coupled to said central processing unit for storing program and data information; and 4) an input/output unit coupled between said processor and said touch screen for carrying out information transfer therebetween, said input/output unit further including: a) a sensor input coupled to each said environmental condition sensors for receiving said electrical signal therefrom; and b) a control output coupled to the space conditioning equipment for issuing control signals thereto; and D) a control program stored in said memory for causing said central processing unit to communicate through said input/output unit to selectively: 1) establish on said liquid crystal display a first representation produced by a first mode comprising a plurality of virtual buttons for detecting user input that controls operation of one or more components of space conditioning equipment and a plurality of items of information or graphics on the liquid crystal display; 2) detect the occurrence of first condition which causes a change from operation of the first mode to operation of a simple mode in the control program; and 3) activate the simple mode and display on said liquid crystal display a simple representation produced by the simple mode comprising fewer virtual buttons and items of information or graphics than displayed in the first mode. 2. The programmable thermostat system of claim 1 in which said first mode established on the liquid crystal display a menu virtual button representing means to select among three or more functions of the control program. 3. The programmable thermostat system of claim 2 in which the menu virtual button is eliminated from the simple representation upon activation of the simple mode. 4. The programmable thermostat system of claim 3 in which the only two virtual buttons, an increase virtual button and decrease virtual button, are present in the simple representation upon activation of the simple mode, whereby the increase virtual button represents means for increasing a setpoint for initiation of operation of space conditioning components and the decrease virtual button represents means for decreasing a setpoint for initiation of operation of space conditioning components. 5. The programmable thermostat system of claim 2 in which the menu virtual button is present in the simple representation upon activation of the simple mode although the menu virtual button represents means to select from two or fewer functions of the control program. 6. The programmable thermostat system of claim 5 in which there are two functions of the control program that are selectable by pressing the menu virtual button, where such functions are those functions that, one, control operation of space conditioning components for heating and, two, control space conditioning components for cooling. 7. The programmable thermostat system of claim 1 in which the first condition is the occurrence of a reset of the control program. 8. The programmable thermostat system of claim 1 in which the first condition is the occurrence of a re-powering of the programmable thermostat system. 9. A programmable thermostat system for controlling space conditioning equipment comprising: A) at least one environmental condition sensor providing an electrical signal indicative of the ambient temperature of a conditioned space in which said environmental condition sensor is situated; B) a transparent touch pad juxtaposed with a liquid crystal display to constitute a touch screen for interactive interface with a user; C) a processor, said processor including: 1) a central processing unit; 2) a real time clock; 3) a memory coupled to said central processing unit for storing program and data information; and 4) an input/output unit coupled between said processor and said touch screen for carrying out information transfer therebetween, said input/output unit further including: a) a sensor input coupled to each said environmental condition sensors for receiving said electrical signal therefrom; and b) a control output coupled to the space conditioning equipment for issuing control signals thereto; and D) a control program stored in said memory for causing said central processing unit to communicate through said input/output unit to selectively: 1) establish on said liquid crystal display: a) a first representation produced by a first mode comprising a plurality of virtual buttons for detecting user input that controls operation of one or more components of space conditioning equipment and a plurality of items of information or graphics on the liquid crystal display; 2) detect the occurrence of first condition which establishes on the liquid crystal display a second representation comprising a notice to a user to make a first input that will initiate a change from operation of the first mode to operation of a simple mode in the control program; 3) detect the occurrence of the first input, which then causes a change from operation of the first mode to operation of a simple mode in the control program; and 4) activate the simple mode and display on said liquid crystal display a simple representation produced by the simple mode comprising fewer virtual buttons and items of information or graphics than displayed in the first mode. 10. The programmable thermostat system of claim 9 in which the first input is a detection that a user has pressed the liquid crystal display. 11. The programmable thermostat system of claim 9 in which the simple representation consists of four or fewer virtual buttons and three or fewer items of information. 12. The programmable thermostat system of claim 11 in which the simple representation consists of three or fewer virtual buttons and three or fewer items of information. 13. The programmable thermostat system of claim 9 in which said liquid crystal display is a dot matrix type. 14. The programmable thermostat system of claim 9 in which said liquid crystal display is a segment type. 15. The programmable thermostat system of claim 9 in a user must make the first input of step D)2) within a pre-set time from the occurrence of the first condition or the first mode will operate within the control program. 16. The programmable thermostat system of claim 15 in which said pre-set time is about 30 to 60 seconds.
