1. An electronic controller for controlling the energization states of a plurality of electrical loads, said controller comprising:

  • a plurality of load control circuits, each said load control circuit being adapted to be interconnected with a load, and having a load-on state when its load is to be on, and a load-off state when its load is to be off;

    clock means for determining real-time;

    sensor means for sensing at least one environmental temperature at a facility at which the plurality of electrical loads are located;

    event memory means storing a time schedule for real-time control of the plurality of electrical loads;

    program memory means storing a set of program instructions; and

    ,program means responsive to said set of stored program instructions for;

    obtaining said time schedule from said event memory means;

    obtaining a sensed environmental temperature from said sensor means;

    modifying said time schedule in accordance with said sensed environmental temperature;

    obtaining real-time from said clock means; and

    ,placing said load control circuit for each load in said load-on and said load-off states by comparing said real-time with said modified time schedule.
