2.6. AUTO mode

During AUTO mode, ventilation intensity is adjusted by a weekly schedule or air quality in the premises, i.e. ventilation is
activated only when necessary or desired.

2.6.1. Weekly operation schedule

If you want the unit to operate when you need it, you can create a weekly operation schedule. The unit has 3 default
weekly operation schedules tailored to different situations. Also, you can create your own schedule:
Working week
At night the unit operates in AWAY op-
eration mode, and in the morning or
evening it switches to NORMAL opera-
tion mode.
The unit is switched off during the
working day.
Programs, times and days of a schedule may be changed (see chapter "Control and Settings").

2.6.2. Air quality control function

Air quality control function activates ventilation only when necessary, i.e. when the air quality is poor. If the indoor air
quality is good, the unit will ventilate at minimum speed or stop. Air quality in the premises may be controlled by impurity
or humidity sensors connected to B8 and B9 terminals of the main board (see "Installation Manual").
Air quality control function is not available in VAV air flow control mode (see "Air Flow Control"). In this
case, the unit will operate by a weekly operation schedule in AUTO mode.
As air impurity and humidity control methods slightly differ, the air quality control function is divided into:
• Impurity control
Impurity function is controlled via the following sensors:
CO2 – carbon dioxide concentration sensor [0...2000 ppm];
VOC – air quality sensor [0...100 %];
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-defined 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 modified (see "Control and Settings").
• Humidity control
Humidity control function allows dehumidification of air in the premises. Possible ways of dehumidification:
1. If outdoor humidity is measured via an additional humidity sensor, air in the premises will be dehumidified when
humidity level outdoors is lower than indoors. Indoor humidity is monitored by a separate sensor connected to a
controller board or 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 dehumidification of the premises is necessary, the fan speed will be increased gradually and
drier air will be supplied.
