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) .
