Swegon CASA W3 Smart Instructions For Use Manual page 109

The automatic humidity system measures
the daily average value in the extract air and
compares this with the current value. The
ventilation starts to be boosted variably when
the humidity has risen as much as the Boost
limit value.
When the sauna is working, the ventilation is
boosted with the set value, through the acti-
vation of the automatic sauna limitation. This
function prevents variations in the fan speeds
while the sauna is working.
SUMMER MODE BOOST
Summer mode
The heat exchanger takes care of the cool
indoor air during hot summer days and cools
the incoming outdoor air. At night the air
passes the heat exchanger and the home is
cooled with fresh outdoor air. The settings for
automatic summer operation can be finely
adjusted from summer mode menu.

Cooling (supply)
For summer operation you need to define
the limit values for the outdoor temperature
and the room temperature, which must be
exceeded for the function to be enabled. The
outside air must be cooler than the room air.
It is possible during summer operation, to
boost the ventilation by activating summer
mode boost from the Smart functions menu.
The summer mode boost makes it possible to
use the cooling rate once the set limits have
been met. The boost function can be limited
by using the weekly program to only allow the
cooling rate at specific times.
Swegon reserves the right to alter specifications.
AUTO AIR QUALITY CONTROL
The function is available only on mod-
els equipped with automatic air quality.
Automatic air quality boosts the ventilation
variably according to the indoor air quality.

Filter time
The settings menu shows the value
now" the current air quality level. The func-
tion is set by specifying the boost limits where
you want the ventilation boost to start and
the value at which you want the ventilation
unit to reach maximum boost. Appropriate
values can be established based on the
now" value shown in the menu.
If it seems that the ventilation system reacts
too quickly to changes in the air quality level,
14°C
you can increase the filtering time.

TEMPERATURE BOOST
The function is only available in combination
with summer mode and air heaters for heat-
ing/cooling. The function boosts the ventila-
tion variably when the room air needs to be
heated or cooled.

Use in away mode
You can set the gain values for heating and
cooling from the settings menu. The function
boosts the ventilation according to the differ-
ence between the room temperature and setting
value, so that a deviation of one degree results
in boosting as set for the gain value. Boosting is
limited if the supply air is too hot or too cold.
