Operating modes
A 4-pole DIP switch is located inside the solar module casing. This
becomes accessible after removing the cover or the programming
module.
DIP switch 1 enables the module to be switched ON and OFF. The
anti-seizing pump protection continues to be active even when the
module is switched OFF.
DIP switches 2 and 3 are not relevant here.
DIP switch 4 must be set to ON.
The SM2 solar module can be operated in different modes.
a) SM2 as part of a Wolf control system
The SM2 solar module can be integrated into a Wolf control
system. In that case, the solar module will be controlled from
the programming module BM with address 0. An optional
programming module BM-Solar can also be linked to the SM2.
In that case, the system can be controlled from the BM with
address 0 and from the BM-Solar.

BM
If the solar cylinder is assigned to another BM, the system can
also be controlled from that BM. In systems with two cylinders
that are assigned to two different BMs, the solar module can also
be controlled from those two BMs (see parameter description
SOL07 / P07 and SOL17 / P17).
Note:
Only one SM2 can be integrated into any one Wolf control
system.
