6.6.3. Temperature control modes
The air handling unit provides for several temperature control modes:
•
Supply. The unit supplies air according to the temperature preset by the user.
•
Exhaust. Unit automatically supplies air of such temperature to maintain preset exhaust air temperature.
•
Room. Operation is similar to the mode “exhaust” but temperature is maintained by the sensor mounted in
the room (B8).
•
Balance. Supply air temperature maintenance value will be determined automatically from the existing exhaust
air temperature, i. e., what the air will be removed from the premises, and the same will be returned back.
When "Balance" is selected, the temperature setpoint disappears.
6.7. Functions of the unit
6.7.1. Air quality control
Air quality control is designed according to:
•
CO
2
sensor
1
[0...2000 ppm];
•
Air quality sensor VOCq [0...100 %];
•
Air pollution sensor VOCp [0...100 %];
•
Relative humidity sensor [0...100 %];
•
Temperature sensor [0...50 °C].
Depending on the type of the selected sensor, the value of the air quality function to be maintained is set, and
the air handling unit intensity will be adjusted according to that value. Ventilation intensity will be increased au-
tomatically in the case of deviation from the set value and decreased again when it is approached. For example,
if the unit is designed with the CO
2
maintenance function and is equipped with a CO
2
sensor, after setting value
800 ppm, this set CO
2
level will be maintained by adjusting ventilation intensity, i. e. ventilation intensity will be
increased if the CO
2
level grows and will be decreased when it returns to the previous condition.
Two air quality value settings for separate unit operation modes are possible.
The function of air quality operates only if no other below function is active
at the same time:
•
Summer night cooling
•
Min. temperature control
•
Recirculation control
•
Outdoor compensated ventilation
