The buffer storage tank is charged with the help of sensor B4 and a switching
differential.
As soon as the temperature at sensor B4 drops 2 K below the required value,
the buffer storage tank will be charged until the temperature at sensor B4 lies
one switching differential above the temperature displayed on operating line
456 (slave pointer).

The buffer storage tank is charged with the help of sensors B4 and B41/B42
(start / stop behavior).
If B4 (top) drops 2 K below the required temperature, the buffer storage tank
will be charged until the temperature at sensor B41 (bottom) reaches the tem-
perature displayed on operating line 456 (slave pointer).
