2.5. Outdoor compensated ventilation
This function adjusts ventilation intensity according to the outdoor temperature. This saves the energy needed for air
heating or cooling. The user sets four outdoor temperatures (two for winter and two for summer) for this function to operate.
As long as the outdoor temperature is outside the summer or winter temperature limits, the unit keeps running in a currently
activated ventilation mode. Ventilation intensity is reduced proportionally to the rising (summer temperature range) or de-
creasing (winter temperature range) outdoor temperature.

Fig. 2 OCV function operation
OCV function is blocked if SNC or REC functions are activated at the same time. This function also has priority over AQC
function.
For information on how to activate this function and set temperature ranges see Chapter “Control and Settings”.
2.6. Minimum temperature control function (MTC)
Minimum temperature control function forcibly reduces the user-defined ventilation intensity when the set minimum
temperature cannot be reached. Fan speed is gradually reduced when the outdoor temperature drops below + 5 ° and the
power of the heat exchanger and heater is insufficient to reach the minimum temperature. If this function runs for a long
time, ventilation intensity is reduced to 20%.
During summer, the minimum temperature control function limits power of coolers when, in case of cooling demand,
supplied air temperature is below the minimum set temperature value.
For information on how to activate this function and set a minimum temperature value see Chapter “Control and Set-
tings”.
2.7. Operation on demand (OOD)
This function turns on the AHU as soon as the indoor air quality decreases. In this way, the air handling unit will only run
when ventilation is required and will remain stopped when the air quality is good. As the air quality decreases and reaches
the user-defined critical limit, the air handling unit starts and runs in the last activated operating mode. If the air quality
improves within 30 minutes (pollution drops 10% below the critical limit), the unit stops. If the air quality remains poor, the
unit keeps operating.
This function requires an additional air quality sensor installed inside the room (see “Installation Manual”). The same
sensor is also used for AQC function.
Sensor type is selected during ordering. Later, the sensor type may be changed in the remote controller menu “Settings”.
For information on how to activate this function and set a critical air quality value see Chapter “Control and Settings”.
