Delete device connections

9 Delete device connections
To delete the device connections between the floor heat-
ing actuator and the wall thermostat, please proceed as
follows:
• Select the channel of the floor heating actuator
to which the wall thermostat is connected using
the select button (B) (see fig. 7).
• Press the system button (A) and the select button
(B) of the floor heating simultaneously until the
LED (A) flashes green.
• Restore the factory settings of the wall thermo-
stat (for further information, please refer to the
user manual of the wall thermostat).

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 trans-
mission process. The failed transmission may be caused
by radio interference (see „13 General information about
radio operation" on page 78). 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 transmis-
sion 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 teach-
in processes mean that it may be reached in isolated
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).
