Weak batteries

Provided that the voltage value permits it, the radiator
thermostat will remain ready for operation also if the bat-
tery voltage is low. Depending on the particular load, it
may be possible to send transmissions again repeatedly,
once the batteries have been allowed a brief recovery
period.
If the voltage drops too far during transmission, the cor-
responding error code will be displayed on the device
(see „7.4 Error codes and flashing sequences" on page
53). In this case, replace the empty batteries by two
new batteries (see „6 Replacing batteries" on page 50).
