Wiring diagram for KWL EC 340 D
IMPORTANT NOTE
☞
Please hand the circuit diagrams to the installer!
Always use deep flush-mounted boxes for the control elements or the sensors (KWL-CO
2
, KWL-
VOC or KWL-FTF). The control line must always be inserted in an empty conduit M 25. It is
important to ensure that the wiring is connected in series and not radially. A deviating control line
must be installed (see circuit diagram SS-1043) depending on the number of bus components and
cable lengths.
