Patent ID: 6961625

Claim:
A characteristic control device which is provided with: a characteristic control module which controls control parameters and is provided separately from a control device which is provided with a basic control module which outputs output values to control output of a control subject based on input data and control parameters which relate the output values to the input data, wherein the input data relate to weather conditions, said characteristic control module comprising: a characteristic storage mechanism which stores basic control parameters associated with characteristic data, and a characteristic automatic modification mechanism which outputs the control parameters to the basic control module, based on the basic control parameters and the characteristic data stored in the characteristic storage mechanism and the input data, said characteristic automatic modification mechanism (i) evaluating current characteristics of operation based on the input data, (ii) comparing the stored characteristic data and the current characteristics, and (iii) modifying the stored basic control parameters associated with the stored characteristic data based on the comparison of the current characteristics with the stored characteristic data, thereby outputting the control parameters.
