5.8 Additional circuit boards, switching contacts,
sensors, plug-in modules, interfaces
ZP 1 and ZP 2 additional circuit boards (both optional),
combination can be selected freely
ZP 1
controls a brine CP (brine EHE controlled/uncon-
trolled) OR supplementary heating (electric, hydraulic, etc.)
OR 3-way air shutter of an earth-air heat exchanger OR
zone control.
ZP 2
is used for filter monitoring with differential pressure
sensor (instead of timer) OR for controlling a pressure-con-
stant operation (instead of volumetric flow constancy).
E-SM EnOcean plug-in module (optional):
For
connection
of EnOcean wireless components.
K-SM KNX plug-in module (optional):
For connection to a
KNX bus system.
ModBus interface (selectable with commissioning soft-
ware)
Modbus interface (TCP/IP and RTU) integrated in the vent-
ilation unit, enables integration in the building control sys-
tem. Parameterisation with the commissioning software.
Up to 5 further
RLS 1 WR
permitted.
ModBus for TCP/IP generally selectable. For RTU, the Mod-
Bus can only be selected if
no
RLS T2 WS
or
RLS G1 WS
is
connected (interface must not be occupied).
External sensors (optional)
External sensors (humidity sensor, CO2 sensor, VOC
sensor) for WS 160 Flat and WS 300 Flat. Also harmful gas
sensor for WS 300 Flat.
The external sensors require a
0-10 V output and a linear characteristic curve. Standard
connection of sensor 1 and 2 at terminal block X12/sensors
at 24 VDC.
If
no RLS 1 WR
is connected, the connections on terminal
block X13/RLS can be used for 2 additional sensors
(sensor 3 and 4, each 12 VDC). For a 24 VDC power supply
to sensors 3 and 4, the voltage can be tapped at the ter-
minals of sensors 1 and 2 (double assignment).
Multifunction contact (switching contact)
Potential-free switching contact for connecting one of the
following components (→ Wiring diagram):
• Alarm display
• Filter change indicator
• Operating display
• Supplementary heating
• Preheating register
• Shutter
• Brine EHE (unregulated pump)
• Cooling function
Home network (Loxone) to Modbus
Loxone building control system can be connected to the
Modbus interface (TCP/IP and RTU) integrated in the vent-
ilation unit. Parameterisation with commissioning soft-
ware.
ModBus for TCP/IP generally selectable. For RTU, the Mod-
Bus can only be selected if
no
RLS T2 WS
or
RLS G1 WS
is
connected (interface must not be occupied).

8 Installation location, operating conditions
• For these ventilation units, a permanent installation in
dry indoor spaces is prescribed, for example in a utility
room.
• Complete all on-site work before installation. The ventil-
ation unit cannot be moved once the duct has been con-
nected.
• The ventilation unit is designed for installation on a ceil-
ing or wall with sufficient load-bearing capacity (min.
200 kg/m³).
• A flat, hard wall surface is mandatory. This avoids vibra-
tion noise.
• The front cover must be removable at all times. Free ac-
cess is important for cleaning and maintenance work:
Working space in front of the unit of at least 70 cm.
• Note the space needed for additional components.
• Only use accessories and spare parts approved by the
manufacturer.
• Select installation position so as to avoid contamination
and draughts.
• Select the installation location and model for the ventila-
tion unit so that noise emissions are kept to a minimum.
If possible, avoid sound bridges with the structure by ob-
serving sufficient distance from other façade elements.
9 Installation of ventilation unit, electrical
connection
The power cable is already wired inside the unit and led
out of the ventilation unit. The control cable of the
RLS 1 WR
control unit (alternatively
RLS T2 WS
) is led into
the ventilation unit and wired on the main board of the
electronics slide-in module.
Observe the Safety instructions supplement.
When working at heights, use suitable ladders/
climbing aids and ensure that they are stable.
Work in pairs and make sure that you are standing
securely and that no one is underneath the unit.
CAUTION Risk of injury if the ventilation unit or front
cover falls down.
Ensure that the ventilation unit and the front cover are
fastened properly. Observe accident prevention require-
ments.
9.1 Installation of WS 160 Flat
Front cover
If the ventilation unit is already installed, before
taking off the front cover be sure that the set of
installation aids included in the scope of supply is
fitted. Observe accident prevention requirements.
M Set of installation aids for front cover
S Locking bolts
1. Fix set of installation aids for front cover as shown.
2. Attach retaining screw on opposite side. Not necessary
before initial installation if the ventilation unit is on the
ground.
3. Remove the 8 screws that hold the front cover in place.
4. Unscrew retaining screw.
5. Remove front cover
6. When installing for the first time (ceiling, wall), take out
the air filters and heat exchanger.
To fit the front cover, proceed in reverse order.
Ensure that the cover is seated correctly and no in-
filtration air can be drawn in.
