Programming/test button: short press to set programming mode. If this button is held while plugging the device into the KNX bus, it enters the safe
mode. If this button is held for more than 3 seconds, the device enters the test mode.
Programming/Test LED: programming mode indicator (red). When the device enters into safe mode, it blinks (red) every half second. The manual
mode is indicated by the green color. During the start-up (reset or after KNX bus failure) and if the device is not in safe mode, it starts a blue blinking
sequence.

SAFETY INSTRUCTIONS
Installation should only be performed by qualified professionals according to the laws and regulations applicable in each country.
Do not connect the mains voltage nor any other external voltage to any point of the KNX bus; it would represent a risk for the entire
KNX system. The facility must have enough insulation between the mains (or auxiliary) voltage and the KNX bus or the wires of
other accessories, in case of being installed.
Once the device is installed (in the panel or box), it must not be accessible from outside.
Keep the device away from water and do not cover it with clothes, paper or any other material while in use.
The WEEE logo means that this device contains electronic parts and it must be properly disposed of by following the instructions at

.
⚠
In order to ensure the expected
status of the relays, please check
that the device is connected to the
KNX bus before energizing the
power circuit.
