Functional assignment of
the switch contact inputs
The 12 switch contact inputs on the HMW-Sen-SC-
12-FM can only be assigned to other HomeMatic
components by means of the HomeMatic central
control unit, they cannot be connected to other
components directly.
Since this device does not feature any control
elements, all operation and configuration work
is performed via the "HomeMatic WebUI" user
interface that runs as web user software on the
HomeMatic central control unit, which in turn works
as a web server. Once the teach-in procedure
described below has been carried out, the device
will be available in the HomeMatic system.
