Caution - illustration shows principle only!
This system schematic does not include all
the shut-off and safety devices necessary for
professional assembly. System-specific plan-
ning is required!
You can connect the first boiler directly to the eBUS on
the controller. Note the polarity when doing this.
From the second boiler onwards, a bus coupler is neces-
sary.
