Air impurity function automatically selects ventilation intensity in the range of 20–70%, based on air quality readings. If
air pollution is within the user-dened limits, fans will operate at minimum speed; as level of pollution increases, the unit will
increase ventilation speed and supply more fresh air to the premises. It is also possible to stop the unit when air pollution is
low. For this purpose, change a minimum ventilation intensity limit to 0% (see “Control and Settings”). Then the unit will turn
on periodically (every 2 hours by default) to inspect the air quality, and will ventilate until pollution is reduced, if necessary.
Type of connected sensors and range of ventilation intensity may be modied (see “Control and Settings”).
• Humidity control
Humidity control function allows dehumidication of air in the premises. Possible ways of dehumidication:
1. If outdoor humidity is measured via an additional humidity sensor, air in the premises will be dehumidied when
humidity level outdoors is lower than indoors. Indoor humidity is monitored by a integrated in a control panel. In the
settings: set sensor type RH and select one of the connected sensors for measuring outdoor humidity (see “Control
and Settings”). In AUTO mode fans are running at minimum speed as long as the indoor humidity is lower than the
setpoint (see “Impurity Control”). When humidity outdoors is lower than indoors and dehumidication of the prem-
ises is necessary, the fan speed will be increased gradually and drier air will be supplied.
2. If no outdoor humidity sensor is used, “Humidity Control” function operates the same way as the “Impurity Control”
function but instead of an air quality sensor, optional humidity sensor connected to the controller or integrated in the
control panel is used.
3. If an external DX unit or a water cooler is used (activated in “Control Sequence Settings”), additional dehumidication
is possible by cooling supply air. In this case, the supply air temperature setpoint is ignored and colder but drier air is
supplied until the desired indoor humidity level is reached. If an outdoor humidity sensor is used and the outdoor air
is drier, the unit will attempt lowering the indoor humidity by supplying drier outdoor air before activating cooling
units. Dehumidication with cooling devices is possible both in AUTO and standard ventilation modes.
To use a DX unit or a water cooler for dehumidication of supply air, activate an option “Allow dehumidifying with cool-
ing” (see “Control Sequence Settings”). An option to enter a value for desired humidity will appear in the settings of standard
ventilation modes.
