<p>The digital temperature controller, features a display where a sequence of data and questions is displayed, required for installation and use. The messages are displayed in full text. The use of any symbols except letters, numbers and standard characters is excluded. All control parameters are modified only by two buttons. All questions and information required during installation and use are stored in the memory of the controller. Additional written instructions are not necessary. The controller can thus really be used by any literate person. Since it supports full duplex communication it provides the possibility of monitoring and controlling the state of the system from a distant or near-by control room. By using calorimeters, integrated into the controller, the compactness of the solution in heating substations can be increased.</p> |
