•

The professional installation of bus lines and commissioning of devices requires compliance with
the provisions of EN 50428 for switches or similar installation equipment for use in building
construction technology. Tampering with, or making modifications to, the device invalidates the
guarantee

Designated use

• The time switch can be used for lighting, bell systems, ventilation etc.

• Only use in enclosed dry spaces (device); antenna is installed in the open-air

Disposal

(2CDG120041R0011) in order to synchronise
the time switch via the DCF/GPS time signal.
With correct reception the synchronisation
occurs automatically after a few minutes.

Settings must be made via the ETS if the
antenna is connected. The settings can be acti­vated via the ETS on the KNX bus.

Programme cycle time

In addition to switch-on and switch-off times (switching time) and short time pulses (pulse) cycle
times (cycle) can also be programmed. The pulse length (+ pulse pause) is limited to 17 hrs,
59 min, 59 sec

• Cycle times refers to cyclically repetitive time functions such as fan controls, urinal rinses etc.

Example: Switch on water rinsing Monday from 8:00 to 20:30 hrs every 15 min for 20 sec
(8:0000–8:00

Cycle programming
– Start cycle: Monday 8:00 hrs

Standard program and extra programs

• The standard program P0 (weekly program with switching times, pulse and cycle times or astro-

nomical program) is always active however has the lowest priority and can be superimposed by
the extra programmes P1–P16.

• In extra programs the following is valid: the higher the number the higher the priority. The extra

program 16 has the highest, the extra program 1 the lowest priority.

• Each extra program has an arbitrary number of date ranges available. A extra program becomes

active when at least one date range has been set and is not superimposed by another extra
program with a higher priority during this period. At the start and end of each date range the
hour can also be entered to ensure that the changeover to the respective extra program occurs
on each complete hour.

• The following date ranges can be set in parallel:
– Fixed date (once)

– Fixed date each year
– Easter rule or the Orthodox Church rule (81 days before ... 174 days after Easter)

19

GB

– Chinese New Year (20 days before ... 20 days after the Chinese New Year)
– Date with serial pattern (Time limit series): Start and end are set and the start repeated

according to an adjustable number of days (at the latest after 200 days)

– Weekday rule (e.g. every 3rd Wednesday in September)

Examples of calendar-dependent date ranges:

– Fixed date range:
Start on 02.04.2012 at 16:00 hrs, End on 24.04.2012 at 10:00 hrs

– Annually recurring date range
Christmas: Start every year on 24.12. at 18:00 hrs, End on 26.12. at 23:00 hrs

– Easter-dependent date range
Whit Sunday and Monday: Start every year: 49 days after Easter at 0:00 hrs,

End: 51 days after Easter at 0:00 hrs

– Date range dependent on the Chinese New Year

Start each year 1 day before the Chinese New Year. New Year, End 5 days after

20

– Date with serial pattern (Time limit series)
as from November 2012 to be carried out successively every 2nd week

Start on Monday 01.11.2012 at 0:00 hrs; End on Monday 08.11.2012 at 0:00 hrs,
repeat start after 14 days

– Date dependent on the weekday etc.
each month on the 1st weekend from Saturday 06:00 hrs to Sunday 18:00 hrs;
start 1st Sunday each month at 06:00 hrs, duration 36 hours
– Public holiday settings
With the help of the PC software Obelisk the public holidays in a country in the set can be set

together, individually processed and transferred to the time switch with the memory card Obelisk
as date ranges.

• Extra program P1-14 Time switch channel

– Active in the programmed date ranges
– Switch timings, pulse and cycle times can be entered as week programs

• Extra program P1-14 Astronomical channel

– Active in the programmed date ranges
– Astronomical times are active (calculated sunrise and sunset times)

GB

21

– Fixed switch-offs (e.g. nighttime interruption) and switch-ons can also be entered as weekly

program in order to superimpose the astronomical times entirely or partially.

Example: The standard program switches on the street lighting in dependence of the astro

times. A nighttime interruption is programmed from 23:00 hrs to 04:00 hrs.
Extra program 1 is active within the date range from April 30, 12:00 hrs until May 12:00
hrs. To ensure that the street lighting remains switched on all night no nighttime interruption is
programmed in the extra program 1.

• Extra program P15

– Function: Fix ON
– Active in the programmed date ranges

• Extra program P16

– Function: Fix OFF
– Active in the programmed date ranges

Example: The car park lighting is switched on and off at fixed times or Monday to Friday

according to astro times. The extra program P 16 Permanently Off ensures that the car park

lighting is not switched on on any public holidays.

22

SIMULATION

During the simulation it is a channel-related total
request. All channel switching entered (standard and
special program, switching times, pulse and cycle
programs) are displayed in the time sequence in which
they are applied.

In the case of an astronomical channel all astronomical
switch-ons and fixed switch-ons / switch-offs are
displayed in their time sequence.

Time signal received with DCF antenna or

GPS antenna

• The time signal can be received via the antenna or the KNX bus. Settings must be made via
the ETS if antennas are connected.

• Suitable antenna: DCF antenna (2CDG120040R0011) or GPS antenna (2CDG120041R0011).

• By connecting the DCF or GPS antenna the time switch can be automatically synchronised via
the DCF or GPS time signal. The time zone can be individually set. Upon receipt of GPS data
the GPS coordinates are also transferred to the time switch.

• After connection to the power supply or resetting there is change to the automatic display
after 70 sec, as soon as the DCF or GPS time signal has been received.

• Align DCF antenna in the direction of Frankfurt am Main (best reception is achieved by
installing on the outside of the building).

• Follow advice in the DCF or GPS antenna operating instructions.

32

NOTE

 When connecting ensure correct polarity.
 Observe maximum cable length of 100 m.
 Align the radio antenna so that the green LED flashes once a second.
 A maximum of 5 365-day time switches can be connected to one antenna.

Setting time zones
After successful synchronisation, the time

zone can be altered in the TIME/DATE menu
option.

 In the submenu TIME (display: SET HOUR)

correct the applicable local time (time
zone).
