Setting the eBUS address
Setting the eBUS address
for cascade mode
When operating several boilers (up to 4 control units R1) in conjunction
with a cascade controller KM, adjust the eBUS address of the boilers in
accordance with the table, below.
You adjust the eBUS address by holding down the reset button with the
system operating. After 5 seconds, the corresponding fl ashing code appears
(in accordance with the table) at the signal ring. Select the corresponding
eBUS address with the DHW temperature rotary selector. Your selection of
the required eBUS address is saved by releasing the reset button.

* Factory setting (individual boiler without cascade mode)
* In conjunction with a cascade module, the fi rst boiler must be set to
BUS address 1.
The assignment of gas boilers or BUS addresses (1), (2), (3) and (4) must
be made on-site. Allocate each BUS address only once.
Note: If only one BUS subscriber (boiler or KM) is isolated from the power
supply, then stop and start all subscribers via a system switch.

Cascade operation In conjunction with the KM cascade controller, between 1 and 4 R1 control
units can be linked up.
Communication is realised via the two-wire BUS. Each boiler has an
eBUS address assigned. The KM provides each boiler with the modulation
level (0...100%) and an enable command, upon which every boiler must
operate.
The R1 starts as soon as the KM issues a modulation level greater than
0. Cylinder heating continues in the R1. The emissions test operation can
only be enabled via the heating rotary selector at the R1.
After the burner has been shut down there will be no more cycling block.
In cascade mode (modulation level >0) the boiler circuit pump automatically
becomes the feed pump.
If modulation level > 0 then pump ON.
