1. A method of controlling a temperature regulating system, comprising the steps of:

  • defining a performance index that indicates a desired balance between maintaining a user selected setpoint temperature and conserving energy costs;

    determining a current energy cost;

    determining a value of the performance index using an optimal control solution and the current energy cost; and

    adjusting a sensitivity of the system to a difference between the setpoint temperature and a current actual temperature according to the performance index value.
