This regulation takes into account two exceedance and undershoot limits, resulting in six freely definable control ranges. Depending on the slope of the temperature change, the opening value or opening time of position objects or switching objects is calculated differently within these ranges. As a result, the proportional proportion can also be reduced completely, depending on the slope. Overshoot and undershoot can thus be avoided. At the same time, a short heat-up time is guaranteed.
Four operating modes are provided for each room, for each of which a set temperature is specified (comfort, standby, night, frost protection). Window contacts are of course also taken into account (-> operating mode change “frost protection” as long as the window is open, then return to the currently selected operating mode). The time course of the operating mode can be conveniently specified for each room via a time program. The operating mode can also be changed via a telegram. A function for “comfort extension” (party button) is included.
In the example, different parameters can also be specified for different room types. This makes it easier to make suitable settings for different types of heating.
