P 14 Sensor type CO2
Volumetric flow, demand controlled by CO2 of the extract air
P 14 Sensor type VOC
Volumetric flow, demand controlled by external measuring transducer (VOC)
P 14 External control
External volume flow control via 0 - 10 V input (see wiring diagram).
P 23 and P 24
These settings can be found in the measuring range of the used measuring transdu
-
cer. The measuring range is already preset for devices with integrated CO2 sensor.
P 20 Air quality
When using external measuring transducers, the maximum air flow rate can be
adjusted by parameter P 20.
Example:
Class room
CO²:
max. set-point e.g. 1400 ppm
VOC:
max. set-point e.g. 1400 ppm
P 19 Intermittent ventilation supply air / P 28 Intermittent ventilation extract air
The air handling unit runs on closing the external contact to the motion sensor and in Level 3 at the
volume flows set in P19 and P28.
P 15 Minimum ventilation supply air / P 16 Minimum ventilation extract air
The volumetric flow can also be adjusted to „MINIMUM VENTILATION“ (night setback). This parame
-
ter is controlled using the timer switch or Level 1 and can be set across the entire air volume range.
P 17 Basic ventilation supply air / P 18 Basic ventilation extract air
The designed volume flow for the „BASIC VENTILATION“ is set in m³/h on the control unit and regula
-
ted via the parameters P17 and P18 at Level 2 The volumetric flows can be individually set for supply
and extract air. To achieve the correct building ventilation, the supply air volume must be adjusted
according to the extract air volume. Complex adjustments are thus not necessary and the air volume
for the building ventilation can be adjusted exactly.
Example: Measuring area sensor 0 - 5000 ppm
P 23 = 0
P 24 = 5000
P 14 Sensor type humidity
Volumetric flow, demand controlled by external measuring transducer (humidity)
