Connection example for cascade connection
For solid fuel boilers, the buffer volume can be increased
with a buffer module by cascade connection of a SOLUS.
The buffer module is charged by the solid fuel boiler and
discharged by the heating circuit. The solar power system
charges the SOLUS, which is discharged via hot water tap-
ping, with the result that the buffer module remains cold in
the summer.
