"DBT Timer" app download

Connect the Smartphone to a time switch:

With the APP it is possible to:

Priority list on/off

In case in which, on the same channel, on/off programs are provided with different period (daily or weekly) to carry out in the same day, only the program with the highest priority is executed.

Priority list on/off

From this example it's possible to see that the daily event on Monday is not carried out because in the same day it is provided 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

The holiday program just begins and ends exactly at the specified times.

Holiday program

Programs priority

The priority programs defines how DWTL1 manages the case in which programs with different period are running at the same time (1 indicates higher priority).

Programs priority - Part 1

* Date: s elect 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.

DWTL1 can be configured as a switch"astronomical with probe" or as "programmable twilight". The following diagrams show the operation in the case.

The device leaves the factory configured as "astronomical with" and the set program 1.

Programs priority - Part 2

Astronomical operation during the night and with daytime switching on thanks to the twilight probe if the brightness falls below threshold.

Programs priority - Part 3

Programmable twilight operation with switching on when the brightness falls below the threshold and only if the programming requires it.

Hereby, ABB S.p. A. declares that the radio equipments type DWTL1 is in compliance with Directive 2014/53/EU. The full text of the EU declaration of

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.

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 use of lock and key, controlled by qualified electrical personnel.
