(hold button pressed for at least 4 seconds).
If the device is in teach mode, hold the (first) channel
button pressed down for at least 4 seconds. The
actuator reset is indicated by the device LED flashing
quickly.

10 Device LED feedback

10.1 Flash codes

Different actuator states are indicated by the channel
LED/channel LEDs flashing:
Slow flashing
Fast flashing
One long, x-short
(depends on the type
of error)

10.2 Operational status display

As soon as the relay for a channel (or a direction for
the blind actuator) is triggered, the respective channel
LED will be illuminated continuously.

After configuring the actuator with the center or a
programming tool, the device LED indicates other
device states besides those described. More relevant
information is provided in the configuration instructions
for the devices and in the system manual.

11 Behavior after power restoration

After switching the operating voltage on (mains
voltage returned), the actuator checks the respective
components. If an error is detected, it is indicated
by all channel LEDs flashing (the LEDs for both
directions flash for the blind actuator). This is repeated
continually and the device starts to work with the
respective functionality.
If the test runs without any errors, the actuator sends a
radio telegram with the respective status information.
The actuator waits a random delay time before
sending so that all actuators are not sending at the
same time when the power returns (after a power
outage or shut-down).
During this time, the channel LEDs flash (like in teach
mode). If the delay time is short, the flashing may not
even be noticeable.
