HomeMatic HmIP-STH Mounting Instruction And Operating Manual page 41

• Turn the sensor over to remove the batteries.
• Insert two new 1.5 V LR03/micro/batteries into
the battery compartment, making sure that you
insert them the right way round (see figure 7).
• Put the sensor back into the frame. Make sure
that the clips on the mounting plate latch into the
openings on the sensor.
• Please pay attention to the flashing signals of the
device LED while inserting the batteries (see „7.4 Er-
ror codes and flashing sequences" on page 44).
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.
Caution! There is a risk of explosion if the battery
is not replaced correctly. Replace only with the
same or equivalent type. Never recharge standard
batteries. Do not throw the batteries into a fire. Do
not expose batteries to excessive heat. Do not
short-circuit batteries. Doing so will present a risk
of explosion.
Used batteries should not be disposed of with
regular domestic waste! Instead, take them to
your local battery disposal point.
