The method involves determining temperatures at a collector (1) and in a memory (2), respectively, and calculating a temperature difference between the temperatures. An auxiliary quantities value is compared with a predefined reference value. A pump (3) is switched on when the evaluated value is larger or equal to the reference value or the difference exceeds a preset threshold value. A temperature maximum is determined by monitoring a temporal process. The pump is switched off after determining a defined number of maximum, when the difference is smaller and equal to the threshold value. |
