Extending Pp 45 Ventilation Unit With; Pp 45 Se Sound-Absorbing Elements; Connecting Room Air Controls - Maico PP 45 O Notice De Montage

9.5 Extending PP 45 ventilation unit with

PP 45 SE sound-absorbing elements

Sound reduction
● 1x PP 45 SE: 1,5 ... 2 dB(A).
● 2x PP 45 SE (2nd PP 45 SE turned 45°):
2.5 ... 5 dB(A)
* If two sound-absorbing elements are instal-
led, we recommend turning them 45° away
from each other. This increases the sound
insulation effect.
Install PP 45 SE: Step
1. Take PP 45 SE out of the film and open it
carefully.
2. Remove and dispose of core.
3. Carefully close PP 45 again.
4. Slide the slide-in module (PP 45 O/K/RC),
inside the sleeve, as far as possible out-
wards (towards the outer wall). NOTICE:
Connecting cable must not be installed
tautly.
5. Insert PP 45 SE elements into the wall
sleeve. When doing so, guide the
to
 
connecting cable [9] of the slide-in module
through one or several PP 45 SE. Then
cut PP 45 SE to a suitable length with a
knife or scissors.

9.6 Connecting room air controls

RLS 45 O and RLS 45 K controls
i
with 230 V. Note safety requirements
in Chapter 9.3.
Wired systems
An RLS 45 O or RLS 45 K master room air
control can have a maximum of 3 further
power units and/or slave room air controls of
a similar design added to it.
A maximum of 4 control units can therefore be
deployed in a PP 45 ventilation system.
You can only combine room air con-
i
trols of the same type (either RLS 45 O
or RLS 45 K).
All other room air controls/power units are
connected via the RS 485 interface.
If further room air controls are connec-
i
ted, these must be defined as slaves in
service mode  operating instructions
or installation instructions.
The relevant ventilation units are connected
to the relevant room air controls/power units.
The ventilation units on an RLS 45 O/K are
generally connected directly to the Fan1 or
Fan2 terminal block.
Radio-controlled systems
Radio-controlled ventilation units are operated
by the DS 45 RC radio switch, which can be
used to control all wireless ventilation units in
range.
Alternatively, an RLS 45 K control with PP 45 EO
extension module can also be used. With this
device combination, radios can be coupled
with wired units.
Connections
For possible combinations  Chapter 8.
To install the room air control, we always recom-
mend using a deep recessed-mounted box.
