The cable to the adjacent building is controlled with weather compen-
sation via the heating circuit control unit. The DHW cylinder is heated
with the selected maximum flow temperature. For this, the heating
water is diverted to the DHW cylinder via a valve. By means of the time
switch, the DHW cylinder is reheated in the downtimes (setback peri-
ods).
