Priority list on/off
In cases in which, on the same channel, on/off programs are provided with
different periods (daily or weekly) to carry out on the same day, only the
program with the highest priority is executed. From this example, it’s
possible to see that the daily event on Monday is not carried out because, on
the same day, it is provided with the beginning of the week program (even if
the daily program of Monday begins and ends before the beginning of the weekly
program). Instead, the daily program of Sunday is carried out because it’s the
only one running for that day.
Holiday program
In cases in which, on the same channel, on/off programs are provided with
different periods (daily or weekly) to carry out on the same day, only the
program with the highest priority is executed. The holiday program just begins
and ends
exactly at the specified times
Programs priority
The priority programs define how DWA manages the case in which programs with a
different period are running at the same time (1 indicates higher priority).
Date: select day, month, year (program carried “only once in the life of the
product”). If the month is not specified, the program is carried out all days
xx of all months of the specified year.

Warning – Working with high voltage is potentially lethal. Persons subjected to high voltage may suffer cardiac arrest, burn injuries, or other severe injuries. To avoid such injuries, make sure to disconnect the power supply before you start the installation. Electrical equipment should only be installed, accessed, serviced, and maintained by qualified electrical personnel. Warning – For safety reasons, it is recommended that the equipment is installed in a way that makes it impossible to reach or touch the terminal blocks by accident. The best way to make a safe installation is to install the unit in an enclosure. Further, access to the equipment should be limited through the use of a lock and key, controlled by qualified electrical personnel
