phone.
• Select the menu item “Teach-in device”.
• Remove the cap (A) if required (see fig. 2) .
• Remove the insulation strip from the battery

ity sensor to activate the device. Pairing mode

You can manually start the teach-in mode for an-
other 3 minutes by pressing the system button (C)
shortly (see figure 5).
• Your device will automatically appear in the
Homematic IP app.

plied or attached to the device.
• Please wait until teach-in is completed.
• If teaching-in was successful, the device LED (C)
lights up green. The device is now ready for use.
If the device LED (C) lights up red, please try
again.

climate control) you would like to use the device.
• Allocate the device to a room and give the device
a name.
7 Replacing batteries
If the battery symbol is displayed via the app or an empty
battery is indicated on the device (see sec. “8.3 Error codes
and flashing sequences” on page 36), replace the used
batteries by two new LR6/mignon/AA batteries. You must
observe the correct battery polarity.
To replace the batteries of the temperature and humidity
sensor, please proceed as follows:
• Remove the cap (A) (see fig. 2) and remove the
empty batteries from the battery compartment (B).
• Insert two new 1.5 V LR6/mignon/AA batteries
into the battery compartment, making sure that
you insert them the right way round (see fig 6).
• Replace the cap (A).
Once the batteries have been inserted, the temperature
and humidity sensor will perform a self-test/restart (ap-
prox. 2 seconds). Afterwards, initialisation is carried out.
The LED test display will indicate that initialisation is com-
plete by lighting up orange and green (see sec. “5.1 Gen-
eral notes on installation” on page 29) .
