Cooling (K) - ZILA KST-20 Vento Mounting And Operating Instructions

Climate Controller KST-20 Vento | KST-20 Vento/CO2 | KST-20 Vento/RN
∆aH stands for the minimum distance between the
absolute humidity inside and outside. The default
value is 5g/m³.
The desired humidity describes a desired humidity
level in the concerned room, which must be
maintained by the climate control system. The input
range is between 40% and 60% of the relative
humidity. This can be adjusted in 5% steps.
Ventilation with speed-controlled fans
In basic ventilation, the KST-20 Vento climate
control system controls the speed-controlled fans at
the minimum speed (DZMIN). To reach the
maximum speed, the climatic condition aH
aH +10g/m³ must be fulfilled.
outside
In between, the speed is controlled linearly
depending on the climatic conditions.
Basic ventilation only continues with DZMIN until
the desired humidity is reached or the absolute
humidity inside is lower than the absolute humidity
outside.

3.4.3. Cooling (K)

By simply adjusting the configuration parameters,
the device becomes a temperature-dependent
cooling control for factory and production halls,
server rooms and many other sensitive electrical
systems.
cooling with 1-stage fans
In cooling mode, natural ventilation starts when the
adjustable internal temperature limit (cooling TSP)
is exceeded. When the ventilation is switched on,
the temperature inside the room must be higher
than the temperature limit and the outside
temperature must be at least 2°C colder than the
inside temperature.

Control of cooling aggregates
In the case that T
difference to the outside temperature Ta>Ti-2°C
does not apply, it is possible to operate a cooling
unit in combination with a single-stage or speed-
controlled fan at the second output of the climate
control.
Cooling with 2-stage fans
If 2-stage fans are connected, the second stage is
switched on if the following climatic conditions are
given:
