In the case of any rapid heating up, it is determined whether the room temperature (TR) or the time (t) is first to reach a prescribed reference value T'R,1 or 0. If the first is the case, the rapid heating up is thereby terminated, the end time Z of the rapid heating up is determined and DELTA t = -Z is selected. If, by contrast, the time (t) is first to reach its reference value 0, the rapid heating up is likewise thereby terminated, the measured value TR,M of the room temperature (TR) which is currently valid is determined, and DELTA t = Kn.(TR,1-TR,M)/ DELTA TV,S is calculated. Kn is the previously valid value of a rapid heating-up constant, TR,1 is the desired value of the room temperature (TR) during a period of use following rapid heating up, and DELTA TV,S is an excess of the feed temperature over the desired value during the rapid heating up. Subsequently, in both cases a new value Kn.(tn+g. DELTA t)/tn of the rapid heating up constant is calculated. In this case, tn denotes the previously valid value of the duration of the rapid heating up, and g denotes a damping constant. During the decreasing period following the period of use, TR,i is continuously measured, and the new duration tn = Kn.T' of the rapid heating up is calculated, where T' = (TR,1-TR,i)/ DELTA TV,S, Kn this time representing the new value of the rapid heating-up constant, and it is clarified whether the time t = tn applies. If this is the case, rapid heating up is started. <IMAGE> |
