Setting parameters
The standard settings for all parameters and switching times
are xed and stored in a non-volatile memory. All changes are
permanently stored and will not be lost, even if the power fails
for several weeks. Parameters are programmed via the BM
programming module. Check the description of operation and
setting / modifying parameters in the BM installation and operating
instructions.
Setting of the eBUS address
for Wolf boilers
When operating several boilers (number of boilers >1) in conjunction
with a cascade module, set the eBUS address for each boiler in
accordance with the table below.
* Address 0 cannot be changed at the Wolf boiler control unit COB. If only one Wolf boiler
control unit COB is installed in the system, then the address remains at its factory setting
(address = 1).

Hold down the reset button; after 5 seconds, the corresponding

address with the DHW temperature rotary selector. Then release
the reset button again.
The assignment of gas red 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.
