There are provided a control apparatus capable of controlling a controlled object with reduce dead time in sign inversion between the input to and the output from one of \u0394\u03a3 and \u03a3\u0394 modulation algorithms, thereby attaining improved convergence of the output from the controlled object to a target value and improved controllability. Upon being prompted by a user, the home energy management device can create a private network for a limited period of time. The rendered version is unaffected by the unrenderable designator because it does not result in any displayable features.
