Product and Applications Description
The 4-channel time switch REG 372 (annual scheduler)
and the 4-channel time switch with DCF77 REG 372/02
(annual scheduler) are DIN rail mounted devices for
mounting in distribution boards. The connection to EIB is
made via a bus connector.
Besides the terminals for the DCF77 antenna AP 390
(5WG1 390-3EY01) the REG 372/02 has terminals for
230V. All other features are identical for both time swit-
ches.
The time switch offers: 324 switching times for select-
able daily, weekly, and date instructions, impulse instruc-
tions, priority switching times, as well as 1 x instructions
for vacation / holidays. For each channel, additionally 9
further week programs with priority levels P1 to P9 and a
time-limited permanently switched circuit can be pro-
grammed besides the normal week program.
Likewise a random program can be activated.
The period of a priority program is determined by input of
a beginning and final date.
The time switch calcualtes moving holidays (like Easter)
automatically for each year.
Priority program
The programming of a priority program consists of:
1. input of switching times
2. determination of a beginning and a final date
If the period of several priority programs overlap, then
always the program with the highest index is active. For
example the week program P2 overrides the week pro-
gram P1.
Special programs
For each channel, additionally 9 further week programs
with priority levels P1 to P9 and a time-limited perma-
nently switched circuit can be programmed besides the
normal week program.
These weekly programs can be activated with start and
end date.
Example: weekly program no. 5 from 24 Dec to 6 Jan.
Additionally instructions for a single date and 1x date in-
structions can be added to any weekly program.
Via priority ON and OFF instructions the schedule can
be masked by beginning and final date. The random
program may also be activated.
Accessories
Antenna for DCF77 reception 5WG1 390-3EY01
(only for REG 372/02)
Programming set Obelisk 5WG1 810-0EY01
Obelisk memory card 5WG1 810-8EY01
Random program
The random program causes random on and off switch-
ing in the period from 10 to 120 minutes between one or
more switching pairs (switch on and off time). For each
channel the random program can be switched on manu-
ally via keyboard.
Function „1x“
The function „1x“ can be used for date specific switching
times and for priority periods. A „1x“ function is only exe-
cuted once and then automatically deleted at midnight in
the clock. Likewise a priority period which was occupied
with the function „1x“ is deleted after the operation time.
However, the switching times associated with the priority
period are preserved in the clock.
The function „1x“ can thus be used meaningfully with the
programming of the time switch program for holidays
and holiday programs as well as movable holiday pro-
grams.
Time synchronisation
The time synchronisation of the time switch can be cho-
sen to be made via reception of a date and time bus te-
legram message, automatically quartz-controlled, or by
in the case of REG 372/02 by the DCF77 radio signal
(antenna and mains power is required).
Programming of switching time programs
Complete switching time programming can be made di-
rectly on the device by means of key input or by the PC
programming set Obelisk. The software runs under Win-
dows 95 and higher. By clicking the mouse, the input of
the different switching times takes place fast and simply.
The transfer of the program is made by an EEPORM
memory module (OBELISK), which is read in afterwards
at the PC’s interface and afterwards is put and read into
