9.6.3 Configuration of sensor 1 / sensor 2
Parameters: Sensor 1 / sensor 2 configuration
Set value: no / yes
Parameters: Sensor 1 / sensor 2 type
Set value: CO , VOC, r. h., digital, external. If di-
2
gital, then start/stop, night-time cooling, flush
mode, motion detector, volumetric flow compens-
ation, supply air mode, operation with exhaust air
system.
Parameters: Name sensor 1 / sensor 2
Set value: Sensor 1, Sensor 2, Sensor 3,
Sensor 4, bathroom, WC, kitchen, bedroom, chil-
dren's room, living room, zone 1, zone 2 yes ac-
tivates the connected external sensors named/
specified by type. The name appears on the main
control unit. If the digital type sensor parameter
is selected, the 24 V supply voltage can be
looped via a pushbutton and returned to the asso-
ciated 0-10 V input (arrow). When the pushbutton
is pressed, the ventilation unit switches to inter-
mittent ventilation for the time stated under Dura-
tion of ventilation level. Once this time has
elapsed, the ventilation unit switches back to the
previously selected ventilation level. For wiring
plans → Installation instructions. If flush mode is
selected, the ventilation unit is operated for the
duration of activation using the set air volume.
Flush mode is used to rapidly overcome excess
demands on ventilation. Pre-requirements for
night-time cooling: T room reference > max-
imum room temperature and T supply air > min-
imum supply air temperature, T outside air > 5 °C;
Timer supplementary heat register bypass inter-
lock elapsed. When night-time cooling is selected
and the afore-mentioned conditions are met, the
ventilation unit is operated for the duration of the
activation with the set air volume with the bypass
open.
9.6.4 Configuration of sensor 3 / sensor 4
Conditions for connecting sensor 3 and sensor 4:
Single control unit inactive parameter
Parameters: Sensor 3 / sensor 4 configuration
Set value: yes / no
Parameters: Sensor 3 / sensor 4 type
Set value: CO , VOC, r. h., digital. If digital, then

Start/Stop, night-time cooling, flush mode, motion
detector.
The function of the original single control unit con-
nection on the RLS terminal is changed to two
more sensor connections:
• 0-10 V inputs on terminal S1+ for sensor 3 and
terminal S2- for sensor 4
• 12 V supply voltage on terminals LD 1 - LD3
The supply voltage of sensors 1 and 2 can be
used for 24 V sensors. Yes activates the connec-
ted external sensors named/specified by type.
The name appears on the main control unit. If the
digital type sensor parameter is selected, the 12
V supply voltage can be looped via a pushbutton
and returned to the associated 0-10 V input (S1+
or S2-) 6 Main menu settings. When the pushbut-
ton is pressed, the ventilation unit switches to in-
termittent ventilation for the time stated under
Duration of ventilation level. Once this time has
elapsed, the ventilation unit switches back to the
previously selected ventilation level.

With linear sensor control for ventilation (Auto
Sensor operating mode), the volumetric flow var-
ies in a continuously variable manner depending
on the current CO2/VOC/rel. humidity concentra-
tion. Minimum limit values apply to reduced ventil-
ation (RV) and maximum limit values for intensive
ventilation (IV). Linear control is used between
the two.
