OK/Alarm output signal, terminals
25-26-27 (volt free)
At terminal 25 (COM), a desired voltage
of maximum 230V, 1A can be connec-
ted. The boiler will transfer the signal,
depending on the boiler situation, either
to terminal 27 (OK) or teminal 26
(Alarm).
Weather compensated controller
BM8
The R600 can be extended with a BM8
controller for weather compensated
operation. Additional to the weather
compensation, the BM8 also provides
clock programs for central heating and
sanitary hot water operation. The BM8
can not control secundary heating zo-
nes!

To be controlled
externally
The BM8 can be integrated in the
control panel of the boiler, but can also
be used as a room unit (with integrated
room sensor for room temperature opti-
misation). The maximum length of the
communication cable between boiler
and BM8 is 100m (consult BM8 docu-
mentation for further details).

2 Outside temperature sensor, to be connected at terminals 105-106
3 BM8, to be connected at terminals 102-103
4 Primary sanitary hot water pump control, to be connected at terminals 19-20-21
5 Sanitary hot water sensor, to be connected at terminals 114-115 (Remove jumper from terminals 113-114!)
Further details about the electrical connections can be found on the wiring diagram.
