2.5.2.1. Air quality control
Air quality control is designed according to:
• CO sensor [0...2000 ppm];
1
2
• air quality sensor VOCq [0...100 %];
• air pollution sensor VOCp [0...100 %];
• relative humidity sensor [0...100 %];
• temperature sensor [0...50 ºC].
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 automatically 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
equipped with a CO sensor, after setting value 800 ppm, this set CO
2
be maintained by adjusting ventilation intensity, i.e. ventilation intensity will be
increased if the CO level grows and will be decreased when it returns to the
2
previous condition.
The function of air quality operates only if no other below function is
active at the same time:
• summer night cooling;
• min. temperature control;
• outdoor compensated ventilation.
2.5.2.2. Operation on demand
The air handling unit start-up function is designed to start the unit which currently
off, when one of the selected parameters has exceeded the critical limit.
The function provided for the start-up of the unit according to:
• room CO sensor;
2
• room air quality sensor VOCq;
• room air pollution sensor VOCp;
• room relative humidity sensor;
• room temperature sensor.
Operation on demand (start-up / shut-down) is performed by the same
sensor which is used in the control of the "Air quality function".
A room sensor with the analogue output (0...10 V DC) should be de-
signed for this function.
2.5.2.3. Outdoor compensated ventilation
The ventilation compensation function adjusts the air volume depending on the
existing outdoor temperature. It is possible to enter four temperature points, with
two of them defining winter conditions and the other two defining summer condi-
tions. When compensation start and end points for both winter and summer sea-
sons are entered (it is also possible to enter only one of them, example only winter
compensation; in this case, the start and the end points of summer compensation
should be the same), the current ventilation intensity will be decreased in propor-
tion according to the outdoor temperature until it reaches the minimum possible
ventilation level of 20 %.
The ventilation compensation function does not operate when sum-
mer night cooling function is active.
