• Remove the empty batteries.
• 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 figure 12).
• Reclose the battery compartment.
• Pay attention to the flashing signals of the device
LED (B) while inserting the batteries (see "9.4 Error
codes and flashing sequences" on page 70).
Once the batteries have been inserted, the radiator
thermostat will perform a self-test and an adaption run,
if required (approx. 2 seconds). Afterwards, initialisation
is carried out. The LED test display will indicate that
initialisation is complete 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 non-
rechargeable 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.
