1.4 START-UP AND POWER LOSS
After the device start-up, it requests date and time through the object “Request Date
and Time”. The group address of this object is the one that must be indicated in Z-
Access to respond to the request.
For proper operation of the buttons, it is recommended not to be pressing them during
the initialization, either after programming or after connecting the external power
supply.
On the other hand, a KNX bus power failure does not imply any change in the
device status since it has external power supply. Therefore, the device will continue
operating normally, although, of course, there will be no communication with the KNX
bus.
