Line no. Operating line
5090 With buffer
No
Yes
If a buffer storage tank is installed, select whether the DHW storage tank can draw heat
from it. When using alternative heat sources, the buffer storage tank temperature is
used as a control criterion for the release of additional heat sources.
No
Hydraulically speaking, the DHW storage tank is not connected to the buffer storage
tank.
Yes
The DHW storage tank is hydraulically connected to the buffer storage tank. This
means that the transfer of heat via Q3 is always possible.
Line no. Operating line
5092 With prim contr/system pump
