10 Electric Connections Accessories
Connection to 0-10V input (Plus version only)
A = Plus version
B = Plus version control board
C = Provision connected to 0-10 V
input; for instance a humidity sensor or
a CO
2
sensor.
Connected provision has its own power
supply.
D = Display Plus version (text “V2”
appears when the provision is active on
input 2.)
X15-1 GND
X15-2 0-10V
X15-3 GND
X15-4 0-10V
If a second 0-10V input is required, if necessary connections no. 1 and no. 2 of the 9-pole connector X15, standard
preprogrammed as switch contact, can be reprogrammed to a second input 0-10V. Modifying parameter 15 from “0” to
“1” makes this input into a proportional 0-10 V input. When using two 0 - 10V inputs, the 0 - 10V input with the highest
flow rate always takes precedence.
If connection X15-1 and X15-2 are programmed as second 0-10V input, parameters 15, 16 and 17 can be used to
modify the various situations the same as for the standard 0-10V input. When the provision is active on the optional
second 0-10V input, the display shows the text “V1”.
Ex factory activated 0 - 10 V input (when active, the display shows the text “V2”)

The Plus versions can be equipped with an
external provision with 0-10 volt control) (e.g.
humidity sensor or CO
2
sensor). This external
provision can be connected to pins no. 3 and
no. 4 of 9-pole connector X15; this 9-pole
connector is directly accessible at the rear of
the top without having to dismount the display
cover (see also page 33).
Connections X15-3 and X15-4 are set as
standard as 0 - 10 V input; it is activated as
standard.
Parameter 21 is set “1” ex factory. When the
connected provision is active, the display
shows the message V2. The minimum and
maximum voltage for connected provisions can
be set between 0 and 10 volt with parameter 22
(minimum voltage) and 23 (maximum voltage).
The minimum voltage for parameter 22 cannot
be set higher than the voltage set for parameter
23; the maximum voltage for parameter 23
cannot be set lower than the voltage set for
parameter 22.
