level. In addition, the algorithm is continuously learning from the previous cycles to reach the
desired CO
₂
as precise as possible.
The settings “room volume” and “CO
₂
flow” are used as a starting point.
The minimum and maximum fan speeds for the CO
₂
period can be set individually. It is
recommended to keep the airflow low to avoid wasting CO
₂
. In addition, the room should be
well sealed.
To ensure an even distribution of CO
₂,
good air circulation inside the room should be
maintained.
Here the CO
₂
function can be enabled or
disabled.
Set the desired CO
₂
concentration here.
(ppm = parts per million)
Set the room volume here.
Unit: (length * height * width) m*m*m = m³
Enter the flow set on the CO
₂
armature or
specified for your CO
₂
generator.
Unit: l/min = litres / minute
The table below can be used as rough

Enter the specified maximum air flow of
your exhaust fan(s) according to the
manufacturer.
With this setting the controller knows how
much air is extracted from the room in a
certain period of time at the current fan
speed. The CO
₂
amount is increased
accordingly.
Set the desired temperature for CO
₂
mode.
When this temperature is exceeded, the
fan speeds will be increased as long the
following MIN/MAX settings allow.
