• If you do not have an empty flush-mounted box
available, you can alternatively replace an al-
ready installed switch by the smart solution from
Homematic IP.
• Therefore, pull the rocker o the frame of the in-
stalled switch. Then pull the frame o the switch
together with the clamping/retaining piece. The
clamping/retaining piece can be transparent,
grey or black (depending on the manufacturer)
and holds the frame onto the switch.
To make removal easier, a flat, pointed object
such as a slotted screwdriver can be used.
• Loosen the fastening of the existing switch and
carefully remove it from the flush-mounted box.
• Disconnect the existing cabling from the switch.
• Connect the power supply unit (A) of the CO2
sensor according to figures 4 and 5. Make sure
that you can read the text on the front after wir-
ing.
• Secure the voltage supply unit using the provided
screws into the flush-mounted box (see figure 6).
• Place the clip-on frame (B) on the voltage supply
unit (see figure 7). Alternatively, you can continue
using your existing (multi-gang) frame with an in-
ner dimension of 55 mm (see figure 9).
