Parallel Operation With Rb-Zf4 And Rb-D1-Zf4; Optional System Components; Sensor (Skd) / Voc Sensor; (Eaq 10/2 Air Quality Sensor) - Aerex Reco-Boxx Rb 170 R Betriebs- Und Wartungsanleitung

4.3.2 Timer RESET for filter replacement
interval
Filter replacement prompt is
displayed on the room air control
every 3 months. We recommend
replacing the filter every 6 months
at the latest. Filter replacement is
simple and requires no tools.
1. Replace the air filter as described in
Chapter 6.2
2. To acknowledge the filter replacement
display, press the OK button for around
3 seconds.
4.4 Parallel operation with RB-ZF4
and RB-D1-ZF4
A change in ventilation stage on the RB-ZF4
room air control is not indicated on the digital
RB-D1-ZF4 control.
A change in ventilation stage on the digital
RB-ZF4 room air control is however indicated
on the 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.

5. Optional system components

5.1 CO

sensor (SKD) / VOC sensor

2

(EAQ 10/2 air quality sensor)

CO sensor for registering carbon dioxide.
2
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 quality.
2
The ventilation unit only reacts to the CO
sensor if ventilation level 2 (nominal venti-
lation) is selected on the RB-ZF4 or
RB-D1-ZF4 room air control.
VOC sensor (EAQ 10/2 Air quality sensor)
for controlling the fans according to the air
quality. The ventilation unit only reacts to the
VOC sensor if ventilation level 2 (nominal
ventilation) is selected at the (RB-ZF4 or
RB-D1-ZF4) room air control.
CO and VOC sensor: The ventilation unit
2
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.
● For CO

control
5.2 RFS humidity control
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 ventila-
tion level 3 to level 2 or 1, this deac-
tivates the automatic function of the
humidity control temporarily. This is
then switched back to active if the
level drops below the humidity
control´s set point once.

6. Cleaning, maintenance

6.1 Safety instructions

● Before cleaning or maintenance work,
2
switch off the ventilation unit with the main
switch [6].
● When you open the front cover, a safety
switch (door contact switch) switches the
fans off. In comfort and bypass units, the
frost protection heating register also
switches off. The bypass in the bypass
units closes.
● Never operate the ventilation unit without
a filter.
