Patent ID: 7983796

Claim:
A method of monitoring and controlling an active environmental control system to impose energy efficient use of the system, the method comprising the steps of: monitoring a calling device for a change in calling data; time and date stamp the change in calling data; detecting a change in status of a plurality of physical sensors located within the system, wherein the state of each sensor represents a condition of the environment in which the system resides; time and date stamp the change in status of the plurality of physical sensors; measuring the temperature of a plurality of temperature locations within the system; time and date stamp the measured temperature of the temperature locations; storing for an extended period the calling data, the status change of the physical sensors and the measured temperature of the plurality of temperature locations, together with the respective time and date stamp, in a memory of the system; filtering the calling data, the physical sensors status change and the measured temperature for a system control trigger to identify system control trigger data; extracting a probability decision, to predict a direction of trend, by comparing recent system control trigger data with prior recorded system control trigger data; weighting the system control trigger data, based on the probability decision that the data is causing an output event trigger, in order to effect a desired change in output; and controlling the system based on the weighted system control trigger data.
