Troubleshooting
10.1 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 transmission may
be caused by radio interference (see „13 General information about radio
operation“ on page 77). 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.
10.2 Duty cycle
The duty cycle is a legally regulated limit of the transmission time of
devices in the 868 MHz range. The aim of this regulation is to safeguard the
operation of all devices working in the 868 MHz range. In the 868 MHz
frequency range we use, the maximum transmission time of any device is 1% of
an hour (i.e. 36 seconds in an hour). Devices must cease transmission when
they reach the 1% limit until this time restriction comes to an end. Homematic
IP devices are designed and produced with 100% conformity to this regulation.
During normal operation, the duty cycle is not usually reached. However,
repeated and radio-intensive pairing processes mean that it may be reached in
solated instances during start-up or initial installation of a system.
If the duty cycle is exceeded, this is indicated by three long flashes of the
device LED, and may manifest itself in the device temporarily working
incorrectly. The device starts working correctly again after a short period
(max. 1 hour).
10.3 Error codes and flashing sequences
10.3.1 Flashing sequences of the system LED (A)
Flashing code | Meaning | Solution |
---|---|---|
Short orange flashing | Radio transmission/ attempting to transmit/ data | |
transmission | Wait until the transmission is completed. | |
1x long green lighting | Transmission confirmed | You can continue operation. |
1x long red lighting | Transmission failed | Please try again (s. „10.1 Command |
not confirmed“
on page 72).
Short orange flashing (every 10 s)| Pairing mode active| Please enter the last
four numbers of the device
serial number to confirm (see „6.4 Pairing“ on page37).
1x long red lighting| Transmission failed or duty cycle limit is reached|
Please try again (see sec. „10.1 Command notconfirmed“ on page 72 or „10.2
Duty cycle“ on page 72).
6x long red flashing| Device defective| Please see your app for error message
or contact your retailer.
1x orange and 1 x green lighting| Test display| Once the test display has
stopped, you can continue.
10.3.2 Flashing sequences of the channel LED
Flashing code | Meaning | Solution |
---|---|---|
Slow flashing | Emergency operation activated | Change batteries of the wall |
thermostat, perform a
communication test, re-position the wall thermostat (if required), replace
wall thermostat if defective
Short double flashing| Radio connection to wall thermostat failed| Re-position
wall thermostat or add a repeater (see sec.
„10.1 Command not confirmed“ on page 72).
11 Restore factory settings
**** The factory settings of the device can be restored. If you do this, you
will lose all your settings.
To restore the factory settings of the floor heating controller, please proceed as follows:
- Press and hold down the system button (A) for 4 seconds until the LED quickly starts flashing orange (see fig. 7).
- Release the system button again.
- Press and hold down the system button again for 4 seconds, until the status LED lights up green.
- Release the system button to finish the procedure.
The device will perform a restart. After the restart, you can again integrate your device into your Homematic IP system.
Maintenance and cleaning
**** The product does not require any maintenance.
Enlist the help of an expert to carry out any maintenance or repairs.
Clean the device using a soft, lint-free cloth that is clean and dry. Do not
use any detergents containing solvents, as they could corrode the plastic
housing and label.
General information about radio operation
Radio transmission is performed on a non-exclusive transmission path, which
means that there is a possibility of interference occurring. Interference can
also be caused by witching operations, electrical motors or defective
electrical devices.
**** The range of transmission within buildings can differ greatly from that
available in the open air. Besides the transmitting power and the reception
characteristics of the receiver, environmental factors such as humidity in the
vicinity have an important role to play, as do on-site structural/ screening
conditions.
Hereby, eQ-3 AG, Maiburger Str. 29, 26789 Leer/Germany declares that the radio
equipment type Homematic IP HmIP-FAL24-C10 is in compliance with Directive
2014/53/EU. The full text of the EU declaration of conformity is available at
