Vento/CO2
The monitoring of CO2 and the climate values only
takes place in the operating mode "ventilation".

8.1. actuators

2-stage or speed-controlled fans can be used as
actuators.
If 2-stage fans are connected, the control is
regulated like:
• Stage 1 (basic ventilation) as soon as the unit
is switched on
• Stage 2, if CO2 limit value is exceeded or at
absolute humidity outside less than inside
With speed-controlled fans, the fan runs at the set
minimum speed DZMIN until the CO2 limit value is
reached. The speed increases linearly up to the set
maximum speed DZMAX depending on the CO2
value. The upper limit for CO2 is set at 3000 ppm.
The speed also changes
whereby CO2 has priority.

8.2. CO2- Measurement

The device also has a CO2 sensor for monitoring the
air quality.
If the CO2 concentration in the room is below the
set limit value, there is no control according to CO2,
i.e. climate control is carried out (aH controlled).
As soon as the CO2 limit is exceeded, the respective
control outputs are activated regardless of the
climate values.
The current CO2 measured value can be displayed
at any time using the PAUSE key (note: the control
outputs also switch off in this case)

8.3. Connection of the sensors

The KST-20 Vento/CO2 is equipped with three
connection sockets for the sensors. The indoor
climate sensor is connected to the upper left beech.
The outdoor climate sensor is connected to the
upper right socket. The lower, central socket is
intended for connecting the CO2 sensor.
