Unit Structure And Positioning - Maico PPB 30 O Montageanleitung

8 Installation
• 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 RLS 45 O or
RLS 45 K control or PPB 30 RC ventilation unit.
Operating voltage for PPB 30 O / PPB 30 K
units = 12 V DC.
• Units/controls not suited for outdoor use. Pro-
tect ventilation units/controls from moisture and
wetness.
• Use RLS/DS controls only outside protection
zones 0, 1 and 2.
• Use PP 45 ventilation units only outside pro-
tection zones 0, 1 and 2.
• Use PPB 30 O PPB 30 K ventilation units only
outside of protection zone 0.
• Use PPB 30 RC ventilation units only outside
of protection zones 0 and 1.
• PPB 30 O units are connected directly to the
fan interface (Fan1/Fan2) of the RLS 45 O or
RLS 45 K control. For electrical connection →
Connection diagram [} 82].
• PPB 30 K units are connected to the RS 485
bus of the RLS 45 K control. If using several
PPB 30 K on an RLS 45 K, the PPB 30 K 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 [} 80].
• PPB 30 RC units are connected to 230V/50Hz
(for electrical connection → Connection and
wiring diagrams [} 80].) The control is carried
out with DS 45 RC radio control.
• The two connecting cables of the PPB 30 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.
• RLS room air control with plug-in connection
terminals for ventilation unit connecting cables.
Connection terminals can be taken off for wir-
ing.
• 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
PPB 30 K units with a button 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 software. Volu-
metric flow compensation is undertaken with
the other PushPull units on the fan interface.
• Manually switched exhaust air mode or intens-
ive ventilation is possible on PPB 30 RC by
means of DS 45 RC or a button (provided by
the customer). The duration of the manually
switched function can be parameterised by the
specialist installer via the service mode.
• Exhaust air mode on a PPB30 O in combination
with an RLS 45 O can be activated by pressing
the "Ventilation level" button for more than 2
seconds. Exhaust air mode generally lasts 10
minutes.
• Exhaust air mode is only possible with a PPB
30 unit type and when 1 unit is used (setting in
service menu). The measurements will be in-
correct if the installation location of the control
and external sensors is inappropriate. Avoid
disturbing influences and direct sunlight.
• RLS 45 O / RLS 45 K with LEDs. For RLS 45
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 example), choose a suitable installation loc-
ation.
• Quiet changeover noises when the fans change
direction of rotation. Do not install PPB 30 in
bedrooms.
