Changing the batteries

If the symbol for empty batteries ( ) appears in the display or in the app,
please replace the used batteries with four new LR6/Mignon/AA batteries.
You must observe the correct battery polarity.
To insert new batteries, proceed as follows:
Open the battery compartments by pulling the cover (F) first down-
•
wards and then forwards (see figure 3).
• Remove the used batteries.
• Insert four new 1.5 V LR6/mignon/AA batteries into the battery com-
partment, making sure they are the right way round (see figure 12).
• Close the battery compartment.
• Please pay attention to the flashing signals of the device LED while
inserting the batteries (see see „9.4 Error codes and flashing se-
quences" on page 63).
Once the batteries have been inserted, the radiator thermostat will perform
a self-test and an adjustment 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 batteries are not replaced
correctly. Replace only with the same or equivalent type. Never re-
charge non-rechargeable batteries. Do not throw the batteries into
a fire. Do not expose batteries to excessive heat. Do not short-cir-
cuit batteries. Doing so will present a risk of explosion.
Caution! Avoid skin and eye contact when handling leaking batter-
ies. Wear suitable protective gloves when removing leaking batteries
and residues from a device. Rinse with plenty of water in the event
of skin contact.
