Central ventilation units KWL EC.. D Pro/WW
Installation and Operating Instructions
The unit airflow rate is controlled automatically depending on the CO
2
concentration or the relative humidity. The airflow
rate is automatically increased with the increase of the respective sensor value. If the set limit value is exceeded, the
ventilation unit will work at max. flow rate capacity.
3.2.17 Vent calibration
The maximum operating point of the ventilation unit is determined during fan calibration. in this respect, the ventilation
unit runs at 100% fan capacity for a defined period of time. The maximum achievable flow rate and the corresponding
static pressure in the ductwork is shown as a result of the ventilator calibration.
The calibration can be activated on the controller > Service menu 2: “Vent calibration“ (see also Page 19).
The calibra-
tion takes around 3-5 minutes before the result is shown on the display!
If a lower operating point is desired, the value can be individually adjusted in the menu after calibration
using the
+/-
keys (see page 19, Service menu 2: Vent calibration).
In the context of commissioning and adjustment of the ventilation unit, the fan calibration must be carried out
before adjusting the ventilation unit! All control dampers should be pre-set to the desired target value, all val-
ves should be completely opened.
