1. Description and
identification

1.1 General

The CO Sensor measures the amount of
2
CO in the air of the room in which this
2
sensor is installed. The device sends
the results to the ventilation system. If
the CO level is too high, the system
2
regulates the ventilation based on the
maximum CO values.
2
As a result, healthy air quality in the room
is maintained.
Reducing high CO
the home is conducive to concentration,
good sleep quality and helps prevent
headaches.
Are there multiple active CO
Sensors in the home? If so then
the ventilation rate is based on
the CO Sensor that transmits the
2
highest ventilation requirement to
the ventilation system.
1.2 Automatic measurement and
control of air quality
This device measures the level of CO
the air of the room in which the device
is active. Depending on the measured
CO level in the air, the device provides a
2
signal to the ventilation system to adjust
the ventilation rate.
If the CO level in the air exceeds the
2
threshold, the ventilation rate is gradually
increased. Increased ventilation reduces
the CO level in the air and thus improves
2
the air quality.

As soon as the CO
below the threshold again, the ventilation
rate is gradually reduced automatically.

1.3 Manually setting the ventilation

The CO
as a controller by the installer, offers
the possibility of setting the degree of
ventilation manually. Refer to section 4
Operation.
A CO Sensor set as a sensor by the
2
installer cannot be used to adjust the
ventilation rate manually.
If a (temporary) manual preset is
selected, the measured CO
no influence on the ventilation rate. In
this case, the ventilation system follows
the manually set ventilation level. This
will remain active for up to 12 hours after
the last manual setting. After a maximum
of 12 hours, the system automatically
returns to control based on the measured
CO values, if the ventilation unit is set
2
to AUTO. If the ventilation unit is set to
MANUAL, the manual setting remains
until it is changed again. Please refer to
the ventilation unit manual.
