An optional 4-way switch is connected to the modular connec-
tor type RJ12; connection X13 to plus pcb. This connector is
accessible after removing the front cover (see respectively
§8.1 item 2).
If a 4-way switch is connected, the settings according to the
table below will be linked to the ventilation modes of the Air
70. The current ventilation mode can only be changed with the
push buttons on the appliance when the switch is on setting 1.

The eBus protocol may for instance be used to link (cascade
control) appliances (see §10.8). Because of polarity sensitiv-
ity, always connect contacts X1-1 to X1-1 and contacts X1-2
to X1-2; the appliance will not work when these contacts are
interchanged.
