ery (e.g. summer operation).

Ventilation units run with fixed direction
of air flow in ventilation or air extraction
mode.
RLS 45 K / DS 45 RC
Ventilation level 1 to 5.
Ventilation level0 (ventilationOff) only
possible if Off function is activated
RLS 45 O : Ventilation level 1 to 5.
Ventilation level0 (ventilation Off) only
possible if Off function is activated.
RLS 45 K / DS 45 RC
Intermittent ventilation with ventila-
tion level5.
Intermittent ventilation can be selected
in heat recovery or cross-ventilation
mode. With PPB 30 K / PPB 30 RC
units, system operation can only be un-
dertaken with basic settings. To switch
on, press key for2 seconds, the
LED flashes slowly. On RC units, the
current operating mode LED flashes
2x,5times. Operating time of
30minutes. The ventilation unit then
switches back to the ventilation level
previously used. To cancel, press a key.
With the PPB 30 RC, the exhaust air
mode is triggered via the touch of a but-
ton (blue operating mode LED
2x2seconds).
In the service menu of the PPB 30 RC,
the intensive ventilation can also be
configured instead of the exhaust air
mode. Abort: Press a key.
RLS 45 K / DS 45 RC
Sleep mode with ventilation level 0.
Sleep mode can be selected in heat re-
covery or cross-ventilation mode. With
PPB 30 K / PPB 30 RC units, system
operation can only be undertaken with
basic settings. To switch on, press key
for 2 seconds, the LED flashes
slowly.
On RC units, all 3operating mode LEDs
light up and then go out one after an-
other. Operating time of 60minutes.
The ventilation unit then switches back
to the ventilation level previously used.
Abort: Press a key.
Intermittent ventilation, sleep mode or
system Off can be activated on RLS 45
K controller with optional switches.
When a function is switched on, the
LED flashes slowly.
Optional button/switch for the PPB 30
K exhaust air or intensive ventilation
mode.
If required, the PPB 30 unit can be
switched to exhaust air mode (45m³/h
without heat recovery) or intensive vent-
ilation mode (ventilation level5 with heat
recovery) using an optional button/
switch. The commissioning software can
be used to set parameters for how long
these functions last and for the start
delay for the switch. Once the time has
elapsed, the ventilation unit switches
back to the previously used ventilation
level/operating mode.
