9.6.2.1.3 Dynamic Air at central exhaust
Dynamic Air allows better detection of the actual airflow in the duct.
Measuring the varying stepless output provides an accurate expression of the output of the ventilation system
according to which regulation can be carried out by varying fan revolutions/the flap position.
Dynamic Air uses a number of Dynamic Air sensors that are placed in the air outlet - either in the central ex-
haust fan bank or in the central duct. For each stepless unit, a number of outlets controlled in parallel and a
number of Dynamic Air sensors can be used.
Air outlet 1-1
Air outlet 2-1
1-16 air outlet
1-16 air outlet
1-3 sensors

Figure 8: Number of Dynamic Air sensors for central exhaust in fan bank
Technically, one sensor is sufficient for 16 air outlets, but SKOV A/S recommends that a Dynamic Air sensor is
installed in every other stepless air outlet in order to ensure optimum regulation conditions.
DOL 834 CE regulates stepless units without sensors based on a calculated output.
When using Dynamic Air for central exhaustion, the regulation
mode must be

DOL 834 CE measures the performance of the ventilation system.
Ventilation control proceeds according to a curve value of the stepless air
outlet(s).
Chimney type
Enter in which kind of exhaust unit the Dynamic Air sensor is placed, DOL
834 CE can adjust the atmospheric measurement according to the dimen-
sions of the exhaust unit.
