1. A method for controlling a thermostat for energy savings comprising:

  • measuring the temperature inside a conditioned space;

    comparing said inside temperature to an existing setpoint for such conditioned space;

    determining that the existing setpoint has been changed to a new value;

    automatically setting a first setpoint of a repeating sequence of discrete setpoints to the new value of the existing setpoint;

    determining a number of discrete setpoints in the repeating sequence of discrete setpoints;

    automatically setting subsequent setpoints in the repeating sequence of discrete setpoints to increments away from the first setpoint, where each successive setpoint is further from said first setpoint;

    returning to the first setpoint after completing a last setpoint in said repeating sequence of discrete setpoints.
