Troubleshooting

8.1

Weak battery

Provided that the voltage value permits it, the garage door
controller 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 pe-
riod.
If the voltage drops too far during transmission, this will be
displayed on the device or via the Homematic IP app (see
„8.4 Error codes and flashing sequences" on page 42).
In this case, replace the empty batteries by two new bat-
teries (s. „7 Replacing batteries" on page 39).
8.2

Command not confirmed

If at least one receiver does not confirm a command, the
device LED (A) lights up red at the end of the failed trans-
mission process. The failed transmission may be caused
by radio interference (see „11 General information about
radio operation" on page 45). This may be caused be
the following:
• Receiver cannot be reached.
• Receiver is unable to execute the command (load
failure, mechanical blockade, etc.).
• Receiver is defective.
