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. In order to perform a KNX Secure factory reset, while the device
is in safe mode, press the button for 10 seconds until the programming LED changes its state.
Programming/Test LED: programming mode indicator (red). When the device enters the safe mode, it blinks (red) every half second. The test 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.

SAFETYINSTRUCTIONS ANDADDITIONALNOTES
•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 (condensation over the device included) 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
https://www.zennio.com/en/legal/weee-regulation.
•This device contains software subject to specific licences. For details, please refer to https://zennio.com/licenses.
