Troubleshooting; Weak Batteries; Command Not Confirmed - eQ-3 homematic IP HmIP-eTRV-CL Montage- Und Bedienungsanleitung

Troubleshooting

If the radiator thermostat is not used for a longer period of time, e.g.
during storage, remove the batteries to avoid damage caused by the
batteries leaking.
Used batteries should not be disposed of with regular domestic
waste! Instead, take them to your local battery disposal point.
9 Troubleshooting
9.1

Weak batteries

Provided that the voltage value permits it, the radiator thermostat will
remain ready for operation even 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 63). In this case,
replace the empty batteries with four new batteries (see see „8 Changing
the batteries" on page 61).
9.2

Command not confirmed

If at least one receiver does not confirm a command, the device LED
(D) lights up red at the end of the failed transmission process. The failed
transmission may be caused by radio interference (see see „12 General
information about radio operation" on page 66). This may be caused
by the following:
• Receiver cannot be reached.
• Receiver is unable to execute the command (load failure, me-
chanical blockade, etc.).
• Receiver is faulty.
