Self-programmable temperature control system for a heating and cooling system

A method for automatically adjusting the temperature control setpoint of an environmental temperature sustaining means for altering the temperature in a space and providing heating and cooling to the space in accordance with the anticipated occupancy status of the space, said method comprising:

• a) providing a temperature sensing means for sensing the ambient temperature in the space and providing an output of the sensed temperature of the space;
• a detecting means for detecting the occupancy status of the space and providing an output of the occupancy status of the space;
• timing means for providing a time interval to the control system;
• and programmed processor means including programmed instructions;
• b) the processor means being connected to the detecting means, the timing means and the storage means to allow monitoring and processing of the output of the detecting means in relation to the interval provided by the timing means in accordance with the programmed instructions to provide information on the past occupancy status of the space, the processor means further being so connected to allow storing of the information on the past occupancy status of the space in a storage means;
• c) the processor means retrieving the stored information on the past occupancy status of the space from the storage means for the time interval provided by the timing means and processing the information in accordance with the programmed instructions to provide an indication of the anticipated occupancy status of the space for the time interval, the processor means providing a signal to a environmental temperature sustaining means for altering the temperature in the space and providing heating and cooling in accordance with the anticipated occupancy status of the space.
