Please pay attention to the flashing signals of the device LED
while inserting the batteries (see „9.3 Error codes and flashing
sequences“ on page 55).
Once the batteries have been inserted, the radiator thermostat will
perform a self-test (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 re-
placed 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 do-
mestic waste! Instead, take them to your local battery dis-
posal point.
