PP 45/PPB 30 are ventilation units with heat
recovery (HR). In heat recovery mode, a
ceramic heat exchanger stores the heat from
the exhaust air flow.
This heat is then transferred to the passing
supply air entering the rooms – heated air
flows into the rooms. The ventilation system
should be switched on permanently.
The fan unit is designed as a slide-in module
and can be removed for cleaning or to change
the filter (PP 45).
PP 45 O/K/RC
In heat recovery mode, the PP 45 ventilation
unit pairs switch alternately between supply
air and exhaust air mode every 60 seconds.
This ensures alternate ventilation and air
extraction.
In cross-ventilation mode (without heat reco-
very), the ventilation units work permanently
in one direction in supply air or exhaust air
mode.
If a humidity, CO or air quality sensor (VOC)

is connected to a room air control, demand-
driven automatic operation with sensor control
can be manually activated. Depending on the
sensor values measured (H, CO
volumetric flow of the units is gradually adjust-
ed. The set operating mode is retained.
PPB 30 O
The PPB 30 O unit is the ideal choice for an
exhaust air room (bathroom, WC, kitchen),
where the room is aerated and ventilated at
the same time.
In heat recovery mode, the two fans inside
the PPB 30 switch from exhaust air to supply
air mode or vice versa every 60 seconds. The
supply air is heated by the ceramic heat ex-
changer using the recovered heat and thermal
energy is extracted from the exhaust air.

In cross-ventilation mode (without heat reco-
very), the ventilation units work permanently
in one direction in supply air or exhaust air
mode.
If just one PPB 30 O unit is connected to the
RLS 45 O control, pure exhaust air mode
(press "Ventilation level" button for more than
2 sec.) is possible. In this case, the pressure
must be compensated via outside air ope-
nings (ALDs).
Both fans then switch to exhaust air (no heat
recovery).
If a humidity, CO
(VOC) is connected to a room air control,
demand-driven automatic operation with
sensor control can be manually activated.
Depending on the sensor values measured
(H, CO
is gradually adjusted. The set operating mode
is retained.
PPB 30 K/RC
The PPB 30 K unit works like the PPB 30 O
described above, but has the following addi-
tional functions:

PPB 30 K  Commissioning software.
PPB 30 RC  Service-mode
with different functionalities:
Automatic operation (regulation) or system
operation (exceeding of value limit).
The operating mode appropriate for your
PPB 30 K can be selected and set via the
commissioning software. For PPB 30 RC
the setting is made in service mode.
