DBT Timer digital time switches

DBT Timer digital time switches
The unique design, with white backlight LCD display, and extreme ease of use with only four
buttons, make DBT Timer ideal to automate the installation functions. The possibility to
configure all digital devices via DBT Timer APP and Bluetooth connection makes the
configuration and installation time even shorter. DBT Timer digital time switches are
equipped with large capacity internal battery to maintain operation without power supply in
order to avoid the risk of program loss and to maintain the time settings in case of power
failure, respective of its duration. DBT Timer digital time switches are equipped with various
DY365 functions such as the impulse, cycle, random and holiday function.

Digital yearly time switch - DY365
DY365 is the digital yearly time switch with 2 channels from DBT Timer range. Thanks to the
two extension channel units DY365 4CE and DY365 2CE, DY365 is able to control up to 8
channels. DY365 can be coupled with DY GPS antenna to allow synchronization received from
the Global Positioning System or with DY DCF77 antenna that allows an automatic
synchronization of the digital time switch with the Frankfurt DCF77 time signal.

Digital weekly time switch - DW
DW1 and DW2 are weekly digital time switches with 1 and 2 channels, respectively. They allow
exclusion of the normal weekly program in every week with the same mode.
DW1
Digital weekly astronomical time switch - DWA
The astronomical switches DWA1 and DWA2, respectively, with 1 and 2 channels,
automatically control lighting circuits depending on the time of sunrise and sunset, greatly
increasing energy efficiency. The programming is in fact based on a mathematical algorithm
able to calculate the time of the rising and setting of the sun in a certain location for each
day of the year. Once powered the device, simply insert date, time, geographical coordinates
and time zone so that it is ready to work. These settings can also be automatically defined
using the DBT Timer APP. The installation of astronomical digital time switches is
particularly useful when using a twilight switch with external sensor is not recommended
because it may be subject to malfunctions caused by air pollution, excessive brightness or
DWA1 vandalism. DWA1 and DWA2 are also indicated for the control of public lighting, shop
windows of shops, neon signs, monuments, facades, illuminated fountains, …

Digital weekly twilight time switch - DWTL1
DWTL1 is digital time switch with astronomical function and external luminosity probe DWS
indicated for the management of the lighting system, luminous signs.
Digital weekly twilight switch with 1 channel allows the exclusion of the weekly
programming. DWTL1 can be configured as astronomical with probe switch which initial
configuration requires the activation of the load from sunset to sunrise and during the
daytime hours in case of low light. Also,it can be used as programmable twilight switch in
which activation of the load occurs when the probe detects a low light condition in case that
daily or weekly programming requires it.
