The parameters for all eight modes are preset at the factory, but each of them can be modified individually.
This requires selecting the desired mode and touching the icon for five seconds. In the window that opens, you
can change the air flow, temperature and deactivate the electric heater in the unit:

2.4.4. ECO mode
ECO – an energy-saving mode to minimize the power consumption of the air
handling unit. The ECO mode has three-fold operation effects:
•
Blocking the electric heater operation in the air handling unit, and blocking of
all external air heating/cooling elements.
•
Activation of the Free cooling function, which at some point blocks the heat
recovery process, if the outdoor coolness has to be used in an energy-ef-
ficient way. Cooling with the outdoor air automatically starts if the room air
temperature is above a set value, and the outdoor air temperature at that time
is lower than that in the room but not below the set min. value. Similarly, in
the case of the opposite temperature conditions. Free heating is carried out.
•
As the temperature control with heat recovery alone will not be ensured at all
times, in the case of an extreme conditions, when the supply air temperature
is below the specified minimum value (in winter) or exceeds the maximum
value (in summer), the unit will try to maintain the temperature by decreasing
the ventilation intensity. If the temperature does not reach the required min./
max. limits over a long period of time, the air volume can be reduced to the lowest possible value (20%).
The ECO mode settings are preset at the factory, but the operation mode can be modified. This requires
push and hold for five seconds the ECO button in the initial start-up window. In the window that opens, you can
change the default settings.
2.4.5. AUTO mode
AUTO – an automatic operation mode when the unit is operating and changing the ventilation intensity based
on the chosen (pre-set) weekly operating schedule.
See more details in Section 2.4.6.3.

However, if at least one air quality sensor is connected to the air handling
unit, the AUTO key will activate the automatic air quality control function.
Then, the ventilation intensity is adjusted, not according to the schedule, but
according to the current air pollution in the room.
