8.1 Installation information

• Only use slide-in module in wall sleeve with ap-
propriate incline to the exterior wall → Shell in-
stallation instructions.
• The slide-in unit (slide-in module + extension
duct) must be appropriate for the wall thickness,
to avoid a ventilation short-circuit (lack of air).
To ensure this, shorten the extension duct ac-
curately.
• Only mount internal cover on flat surfaces and
without any distortion.
• The appropriate mounting material must be
supplied on site.
• For prescribed connection lines → Connection
and wiring diagrams [} 54]:
• Grid connection and 230 V input: Type NYM-J
5G1, 5 mm²
• Control cables: type J-YSTY, 0.8 mm, 4 wires.
Max. 25 m from star point, up to star point max.
4 m
• Imbalance may arise if the maximum stated
cable lengths are exceeded. Observe installa-
tion requirements relating to cable lengths and
types.
• The ventilation units may only be operated us-
ing the voltage and frequency shown on the rat-
ing plate. For rating plate, see FWL-PushPull
RLS or FWL-PushPull RLS-K control or FWL-
PushPull-30 RC (TwinUnit) ventilation unit.
Operating voltage for / FWL-PushPull-30
(TwinUnit) units = 12 V DC.
• FWL-PushPull-30 (TwinUnit) units are con-
nected to the RS 485 bus of the FWL-Push-
Pull RLS-K control. If using several FWL-
PushPull-30 (TwinUnit) on an FWL-PushPull
RLS-K, the FWL-PushPull-30 (TwinUnit) units
should be addressed using the DIP switches on
the board (address 0 = unit 1, address 1 = unit
2, address 3 = unit 3). For electrical connection
and position of the DIP switches → Connection
and wiring diagrams [} 54].
• FWL-PushPull-30 RC (TwinUnit) units are
connected to 230V/50Hz (for electrical connec-
tion → Connection and wiring diagrams
[} 54].) The control is carried out with FWL-
PushPull RLS-RC radio control.

• The two connecting cables of the FWL-Push-
Pull-30 (TwinUnit) fans (in the slide-in module)
are already fully wired (8-pin, coded connector
plug to avoid mixing up the sockets). They are
connected to the circuit board in the ventilation
unit.
• FWL-PushPull room air control with plug-in
connection terminals for ventilation unit con-
necting cables. Connection terminals can be
taken off for wiring.
• When using the sensor-based automatic dehu-
midification function, exhaust air mode runs un-
til the humidity falls 3% below the maximum hu-
midity value limit. Volumetric flow compensation
with other PushPull units is undertaken.
• Manually switched exhaust air mode or manu-
ally switched intensive ventilation is possible on
FWL-PushPull-30 (TwinUnit) units with a but-
ton or switch (provided by the customer). When
using the switch, the start delay can be set. The
specialist installer can set parameters for the
duration of the manually switched functions and
the start delay using the commissioning soft-
ware. Volumetric flow compensation is under-
taken with the other PushPull units on the fan
interface.
• Manually switched exhaust air mode or intens-
ive ventilation is possible on FWL-PushPull-30
RC (TwinUnit) by means of FWL-PushPull
RLS-RC or a button (provided by the cus-
tomer). The duration of the manually switched
function can be parameterised by the specialist
installer via the service mode.
• Exhaust air mode is only possible with a FWL-
PushPull-30 (TwinUnit) unit type and when 1
unit is used (setting in service menu). The
measurements will be incorrect if the installation
location of the control and external sensors is
inappropriate. Avoid disturbing influences and
direct sunlight.
• FWL-PushPull RLS / FWL-PushPull RLS-K
with LEDs. For FWL-PushPull RLS-K, the
brightness can be set and/or switched off using
the commissioning software. If people are being
disturbed by bright LEDs (in bedrooms, for ex-
ample), choose a suitable installation location.
• Quiet changeover noises when the fans change
direction of rotation. Do not install FWL-Push-
Pull-30 (TwinUnit) in bedrooms.
