ABSTRACT:
The present invention provides a system for controlling heating and cooling equipment in an energy efficient manner. The system comprises a microcontroller, a temperature sensor, a motion detector, a telecommunications interface and a control interface for the heating and cooling equipment. The system can override the thermostat control of the heating and cooling equipment and operate the equipment at a first set-back level and a second set-back level. The system will operate at the first set-back level if there is no motion for a pre-determined period. The system will revert to thermostat control if motion is detected within a second pre-determined period, otherwise the system will initiate operation at the second set-back level. The system will operate at the second set-back level until motion is detected or a control signal is received from a telephone. If thermostat control is initiated by a telephone, then the system will disable operation at the first set-back level until motion is detected. The system can be controlled by a telephone located in a remote location or in a room in the building containing the heating and cooling equipment.
