page 10.
6.1.2 Three-step rotary switch with zero position
To operate the ventilation units, you will need a three-step rotary switch with zero position on site. A
suitable example is available from BUSCH-JAEGER, part no. 2710 U, order no. 1101-0-0918.
The three-step rotary switch allows you to activate ventilation level I, II or III. In the zero position,
the ventilation unit is in standby mode.
6.1.3 Optional pushbutton for intensive ventilation and optional LED for feedback
You can start the ventilation unit’s intensive ventilation level with an optional pushbutton provided
by the customer.
If required, you can use an LED to display when the intensive ventilation is active.

universal interface 6119/40 and EIB bus cable
NOTE
The installation must be carried out in accordance with the generally acknowledged rules of tech-
nology.
8.1 Overview of the modules
8.1.1 Board in M-WRG-S/Z-EIB ventilation unit
Fig. 8: Board in M-WRG-S/Z-EIB ventilation unit
NOTE
— The DIP switches and jumpers on the board are preset at the factory.
►Do not change the position of any DIP switches or jumpers.
8.1.2 EIB universal interface 6119/40
To control the M-WRG-S/Z-EIB ventilation unit you will need an EIB universal interface with four
connectionsthatcanbeconguredasinputsoroutputs,e.g.fromBUSCH-JAEGER,partno.
6119/40, order no. 6133-0-0151.
You will need an EIB universal interface with four outputs and two inputs in order to activate all the
ventilation unit functions and signal both feedbacks.
NOTE
The EIB universal interface 6119/40 is not one of the items supplied.

NOTE
— With this wiring, signal A1 from terminal 7 on the board in the ventilation unit is connected
toterminalAontheEIBuniversalinterface6119/40.TerminalAisconguredasaninput.
The consequence of this is that only those functions in which terminal A is interpreted as
open can be activated. In this case, this would be the functions with BCD code 0, 2, 4, 6,
8, A, C, E (see BCD encoding in section 8.3.2.1 on page 17).
— Note which functions are available if the feedback is wired at a terminal other than termi-
nal A.

8.4 Fixing the EIB universal interface 6119/40 in the ventilation unit and
connecting the EIB bus cable
8.4.1 Fixing the EIB universal interface 6119/40 to the network connection cover
►Thread the EIB bus cable through the
opening (item 1 in Fig. 12) in the network
connection cover.
►Re-insert the network connection cover
(item 2 in Fig. 12).
►Pull the glue dot off the Velcro dot (item 3
in Fig. 12).
►Fix the EIB universal interface to the Vel-
cro dot.
8.4.2 Connecting the EIB bus cable to the EIB universal interface 6119/40
►Connect the EIB bus cable to the EIB uni-
versal interface 6119/40, ensuring that the
polarity is correct:
►Connect the “+” bus wire to the red
terminal (item 1 in Fig. 13).
►Connect the “-” bus wire to the grey
terminal (item 2 in Fig. 13).
NOTE
The EIB universal interface will not work if the bus
cables are connected with the wrong polarity.
8.5 Programming the EIB universal
interface 6119/40
►The EIB universal interface 6119/40 must
be programmed by the electrician on site.
8.6 Final tasks
►Attach the cover to the ventilation unit (see section 6.3.4 on page 12).
