Caution! There is a risk of explosion if the batteries are not replaced
correctly. 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 explo-
sion.
Leaking or damaged batteries can cause burns if they come into
contact with the skin, so use suitable protective gloves in this case.
Used batteries should not be disposed of with regular domestic
waste! Instead, take them to your local battery disposal point.

Troubleshooting
9.1
Low battery
Provided that the voltage value permits it, the wall thermostat will remain
ready for operation also if the battery 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 empty battery symbol
( ) and the corresponding error code will be displayed on the device (see
see „9.4 Error codes and flashing sequences" on page 44). In this case,
replace the empty batteries by two new batteries (see see „8 Changing
the batteries" on page 42).
9.2
Command not confirmed
If at least one receiver does not confirm a command, the device LED lights
up red at the end of the failed transmission process. The failed transmis-
sion may be caused by radio interference (see see „12 General information
about radio operation" on page 46). This may be caused by the follow-
ing:
•
Receiver cannot be reached.
•
Receiver is unable to execute the command (load failure, me-
chanical blockade, etc.).
•
Receiver is faulty.
