8 Installation
1. Take off frame of room air control.
2. Connect thePPB 30 O to the RLS 45 terminals
FAN1 and FAN 2. Connect PPB 30 K units to
RS 485 bus.
Information
• The power supply to the PPB 30 K (+) MUST
come from the Fan1 or Fan2 connection. Make
connection according to wiring diagram → Con-
nection and wiring diagrams [} 80].
• A combination of PPB30 O and PP 45 units is
not permitted at the FAN1 and FAN2 connec-
tion terminals of the RLS control.
• No exhaust air function is possible for PPB 30
O units on an RLS 45 K control.
• If a PPB 30 K is running in exhaust air mode,
the PP 45 / PPB 30 O units handle the volumet-
ric flow compensation at the fan interface
(Fan1/Fan2). It is important that the unit type +
quantity are set correctly.
3. Insert room air control in the flush-mounted
box and screw down to flush-mounted box
with 2 screws.
4. Fit frame. Ensure that the sensor opening is
above the PP 45 HYI (if fitted) and that the
frame engages.
5. Commissioning ventilation system→ .
8.8 Installing radio switch (EnOcean)
When radio mode is activated, EnOcean radio
components, such as master or slave units or
sensors, can be taught-in directly on ventilation
units. For range of radio components → Technical

PP 45 Act EnOcean actuator
With the PP 45 Act EnOcean actuator, radio-con-
trolled PP 45 RC PushPull units can be combined
with wired exhaust air units (ECA, ER). Installa-
tion similar to light switch installation; can be
switched on and off at the touch of a button. For
