The EnOcean actuator can be used as a
normal light switch. The wired exhaust air
units (ECA, ER) are switched on at the push
of a button.
At the same time, a radio telegram is sent
to the PP 45 RC master unit. The PP 45 RC
units (master + slave) provide the required
supply air at the exhaust air units.
Learning-in on the PP 45 RC unit (master unit
only) is the same as teaching-in a sensor.
Through the master-slave network, both PP 45
RC units provide 30 m³/h of supply air during
the "Supply air for exhaust air units" function.
We therefore recommend using the PP 45 Act
only with two PP 45 RC radio-controlled units.
The actuator must only be learned-in at the
master unit.
Learning-in PP 45 Act on the PP 45 RC
master unit
1. Switch off mains fuse and prevent from
being started up again.
2. Electrically connect PP 45 Act  Final
assembly kit instructions, connection
diagrams in the appendix.
3. Switch the mains fuse on, ensure power
supply.
4. Check the functions on the exhaust fan.
If these function correctly, switch off the
exhaust air unit with the PP 45 Act.
5. Set PP45 RC master unit to learning mode.
6. Press the T4 button once on the PP 45
Act. The exhaust air unit switches on. The
units are now learned-in to each other.
For installation and commissioning,
i
refer to the enclosed PP 45 Act
installation and operating instructions.
7. Check the functions on the exhaust fan.
If these function correctly, switch off the
exhaust air unit with the PP 45 Act.

11 USB port

The USB port is used to connect a notebook
with the room air control. In conjunction with
the commissioning software ( Internet), set-
tings on ventilation units can be undertaken.

12 ModBus connection

The ventilation system can also be integrated
into the building control technology.
Your specialist installer can configure the RS
485
interface of the RLS 45 O or RLS 45 K control
as a Modbus interface for this purpose. The
interface is set in service
mode or using the commissioning software.
If the RS 485 interface is configured as
i
a Modbus interface, no further com-
ponents (PPB 30 K, sensors, power
units, room air controls etc.) can be
connected at this interface.

13 Service mode

The service mode is described in detail
in the PP 45 and PPB 30 Final assembly
kit assembly instructions. You must read
these instructions before you change the
system parameters.
● In service mode, activate the components
connected to the room air controls.
● Activate the EnOcean or ModBus interface
if RC ventilation units are connected and/or
a building control technology connection is
to be established.
● If room air controls connected in parallel are
released, service mode can be called up
from each control.
● Activate more room air controls, power
units, sensors and EnOcean modules
on the master RLS. More RLS must be
parameterised and addressed as slaves via
service mode.
● Systems with an RLS 45 K control can
also be configured using a PC (USB) and
PP 45-/PPB 30 commissioning software.
● The PP 45 EO EnOcean module can only
be learned-in with the commissioning soft-
ware and RLS 45 K.
