UK | 6 Operating ventilation unit(s)
● With PP 45 K and PP 45 RC units, the shutter
opens and closes automatically (servomotor).
● PPB 30 units do not have a shutter.
Before switching on PP 45 O units, en-
i
sure that all shutters are fully opened.
This is the only way of ensuring perfect
ventilation and air extraction.
6.3 Heat recovery
operating mode
All ventilation units connected to a room air
control run with heat recovery (HR) in alter-
nation.
When the HR function is switched on, the
associated status LED (HR) lights up.
Interconnected PP 45 unit pairs and the two
internal PPB 30 fans switch between venti-
lation and air extraction in 60-second cycles.
The ventilation level can be individually adap-
ted to requirements.
6.4 Cross-ventilation
operating mode
Suited to rapidly venting living spaces or for
cooling (e.g. on summer nights). The air flows
in one direction: Direction of airflow perma-
nently set to ventilation or air extraction, no
heat recovery.
When the function is switched on, the asso-
ciated status LED (cross-ventilation) lights
up. The ventilation level can be individually
adapted to requirements.
6.5 Demand-driven
sensor mode
This operating mode ensures that the air is
dehumidified in response to demand or that
the room air quality is improved depending
on the sensors in the ventilation system.
If required, the ventilation is automatically
adjusted using the humidity, CO
value (VOC) measured by the sensor.
Automatic operation controls interconnected
ventilation units following the stored sensor
characteristics curve (linear course).
Sensor value limits for comfort units can
42
be set with the commissioning software. The
value limits for object or PP 45 RC units are
stored permanently and cannot be changed.
For PPB 30 RC units, the limit values can be
changed via the service mode  Mounting
instructions final mounting set, chapter 10.4.
Demand-driven sensor mode is switched on
manually with PP 45 or PPB 30 O units.
PPB 30 K units automatically regulate de-
mand-driven sensor mode. Operating modes
for PPB 30 K units = automatic or system
operation, setting with commissioning software
(PPB 30 K) or with service mode (PPB 30 RC).
Depending on operating mode, demand-dri-
ven mode is started in a continuously variable
manner (automatic operation) or when the
maximum permitted room air humidity is
exceeded (system operation).
If a ventilation level is set manually on an
RLS 45 K or DS 45 RC when in demand-
driven mode, the ventilation units continue
to run for 30 minutes in this ventilation level.
The ventilation units then switch back to de-
mand-driven mode (automatic operation).

For information about switching on and
i
off  Chapter 2.
PPB 30 K units have an installed
i
humidity and temperature sensor as
standard. Only the measurements of
the internal humidity sensor are taken
into account for humidity regulation.
Measurements from other sensors are
not taken into account.
If the maximum humidity value limit is
i
exceeded, PPB 30 exhaust air mode
can be automatically activated with
maximum air extraction (45 m³/h
without heat recovery) or intensive
ventilation (ventilation level 5
with heat recovery)  Chapter 6.7.
This function can also be started ma-
nually with an optional button or switch
(with start delay/duration activated).
Your specialist installer can configure
i
the way in which the PPB 30 K/RC units
work in automatic or system operation
 Chapter 6.6.
