Climate Controller KST-20 Vento | KST-20 Vento/CO2 | KST-20 Vento/RN

3. product description

The KST-20 Vento is a climate control with "aH-
Controlled" technology
ventilation of private, commercial and industrial
rooms of all kinds.
By means of the connected sensors the climatic
conditions in the inside and outside area are
determined and compared. According to the
measured climatic conditions and the desired
operating mode (dehumidification,
ventilation), the unit controls supply air and exhaust
air elements in a controlled manner. Additional
dehumidification, drying or cooling systems can also
be controlled.
Due to the integrated device functions and the large
number of connectable devices, such as fans,
window openers, louvre dampers, condensation
dryers etc., the KST-20 Vento can be used flexibly in
almost all living, working and industrial areas.

3.2. Standards and Regulations

The KST-20 Vento climate control system complies
with the EMC directive 2014/30/EU under
consideration of the following standards:
• EN 55014-1
• EN 55014-2
EN 61000-6-2
•

3.3. aH-Controlled Technology

The basic principle of ZILA climate control systems
is based on the comparison of the water vapour
content of indoor and outdoor air.
The water vapor content is described by the
absolute humidity (aH = absolute Humidity) and
represents a dimension for the "actual" humidity in
the air. The comparison of the absolute humidity of
indoor and outdoor climate ensures that humid air
is removed from rooms and only drier outdoor air is
introduced.
"aH-Controlled" stands
determination of suitable times for switching on the
supply air and exhaust air elements by the climate
control system, takes the climatic conditions inside
and outside the building into account.
The climate control system controls the most
common single-stage, two-stage and speed-
controlled fans as well as motor-driven window
openers and ventilation louvres fully automatically.
aH-Controlled ensures a healthy building and a good
indoor climate and also works extremely energy-
efficiently, as the building is only ventilated when it
is necessary and air exchange is useful.

3.4. Operating modes

With the KST-20 Vento you can choose between
three operating modes:
ventilation according to DIN 1946-6 and cooling.
Note:
To avoid failures and for optimum
control behaviour of the KST-20
Vento climate control system, the
actuator system suitable for the
respective operating mode must be
used.

3.4.1. Dehumidifying (E)

The KST-20 Vento climate control system is suitable
in dehumidifying mode for mould prevention and
