3.2.4 Digital room air control
RB-D1-ZF4
Optional room air control for RB 600 units.
For detailed information about functions and
settings see  RB-D1-ZF4 mounting and
operating instructions.
The "Plus function" can also be activated with
the RB-D1-ZF4 room air control. In summer
operation, this brings electrical power
consumption savings of approximately 50%.
Timer RESET for filter change interval
A filter change prompt is displayed
i
on the room air control every 3 months.
i
We recommend changing the filter
every 6 months at the latest. Filter
change is simple and requires no
tools.
 Change the air filter as described in
Chapter 6.2.
 To acknowledge the filter change display,
press the OK button for around 3 seconds.
3.2.5 Parallel operation with RB-ZF4
and RB-D1-ZF4
A change in ventilation level on the RB-ZF4
room air control is not indicated on the digital
RB-D1-ZF4 control.
However, a change in ventilation level on
the digital RB-D1-ZF4 room air control is
indicated on the digital RB-ZF4 control.
The ventilation unit always runs in the last
ventilation level set regardless of the room air
control on which this was set.

3.2.6 CO sensor (option)
2
Sensor for registering carbon dioxide CO
The CO content of the air is an indicator of
2
the quality of the room air. The higher the
CO content, the worse the room air.
2
The ventilation unit only reacts to the CO
sensor if ventilation level 2 (nominal venti-
lation) is selected at the room air control
RB-ZF4 or RB-D1-ZF4.
The ventilation unit switches between the
ventilation levels, depending on the air
quality.
● If the air quality improves, the ventilation
unit switches over to ventilation level 1.
● If the air quality worsens, the ventilation unit
switches over to ventilation level 3.
● Please refer to Chapter 9.6.5, connection
option 4 for the switching point of the CO
sensor.

3.2.7 Humidity control RFS (option)

For controlling the fans depending on the
relative humidity. The ventilation unit switches
to ventilation level 3 if the humidity value is
exceeded 75 % r.h. If the humidity in the
room drops, the ventilation unit switches back
to the previously selected ventilation level.
If you switch manually from ventilation
i
level 3 to level 2 or 1, this deactivates
the automatic function of the humidity
control temporarily. This is then
switched back to active if the level
drops below the humidity control´s
setpoint once.
