3. Push button [T] on power unit once.
ð The communication between the FWL-Push-
Pull master and the FWL-PushPull RLS-LT is
established.
8.8 FWL PushPull RLS-K: 230 V input
The 230 V input is switched with a switch/button
to be provided by the customer. In order to use
the additional function, the desired additional
function is selected and activated in service
mode. The following additional functions are
available:
• Sleep mode
• intermittent ventilation
• Safety function (External OFF)
• Supply air mode with overrun time of 0 min.
• Supply air mode with overrun time of 6 min.
• Supply air mode with overrun time of 15 min.
8.9 Modbus interface (building con-
trol system)
With the Modbus parameters in service mode, the
RS 485 interface of the FWL-PushPull RLS and
FWL-PushPull RLS-K controls can be recon-
figured in a Modbus interface → Commisioning
software [} 49].
If the RS 485 interface is configured as a
Modbus interface, no further components
(FWL-PushPull RLS-K, sensors, power units,
room air controls etc.) can be connected at this
interface.

9 System expansions – Connec-
tion of further components
Standard installations are described in the
installation instructions for the FWL-Push-
Pull-45 or FWL-PushPull-30 final installation
kit. These must be read before you proceed
with further connections.
9.1 Safety instructions 230 V connec-
tion
FWL-PushPull-45 RC ventilation units and FWL-
PushPull RLS / FWL-PushPull RLS-K controls
are supplied with 230 V mains voltage. Note the
following safety instructions.
DANGER Danger of electric shock.
Before installing the electrics, shut down all sup-
ply circuits, switch off mains fuse, secure against
being accidentally switched back on and position
a visible warning sign. During operation, the
board cover and front cover of the internal hous-
ing must be mounted.
WARNING Danger of burns/fire due to
overload caused by incorrect connection or
connecting too many units to a FWL-PushPull
RLS / FWL-PushPull RLS-K.
Connect units in accordance with connection dia-
gram. Observe permissible number of ventilation
units per room air control/power unit.
WARNING Danger of electric shock if the
12 V low voltage and 230 V are not disconnec-
ted or are insufficiently disconnected.
Ensure a safety distance between 230 V and
12 V cables (SELV). Ensure minimum distance of
8 mm.
WARNING Danger of electric shock if the
connection on the 230 V input of the FWL-
PushPull-45 RC, FWL-PushPull-30 RC (Twin-
Unit) units and the FWL-PushPull RLS / FWL-
PushPull RLS-K controller is incorrect.
Ensure a phase balance between all components
connected to the ventilation system.
WARNING Danger of electric shock if the
FWL-PushPull RLS / FWL-PushPull RLS-K
room air controls are installed within the pro-
tection zone.
No IP protection present (IP 00). The room air
control may only be installed outside protective
zones 0, 1 or 2.
