COMMISSIONING
Refer to the eWind installation manual for Your ventilation
unit.
The following must be taken into account when
commissioning the cooker hood installation.
•
The fan speed settings and airflow calibration must
be performed as described in the eWind installation
manual for the ventilation unit.
•
For the cooker hood indication mode to function
correctly, the parameter
c12,
fireplace/cooker hood
mode time limit, must be set to
0
. This will omit the
fireplace mode and activate cooker hood mode.
•
The desired ventilation mode is selected from the
eWind operating panel. When the cooker hood flap is
opened the
PdC
(Pressure difference Compensation)
mode is automatically activated and indicated on
the eWind operating panel. When the PdC -mode
is active, the mode of the ventilation cannot be
changed from the eWind operating panel.
•
After performing the normal airflow calibration, the
cooker hood forced ventilation (PdC -mode, when
the cooker hood flap is in the open position) airflow
calibration must be performed. The purpose of this
airflow calibration is to balance the airflows also when
the cooker hood flap is in the open position.
•
The parameters c10 Extract fan speed, fireplace
mode, and c11 Supply air fan speed, fireplace mode
determine the supply and extract airflows during
cooker hood forced ventilation (PdC -mode).
•
During cooker hood forced ventilation (PdC -mode)
the extract airflow must be set high enough to
sufficiently remove airborne contaminations from
the hob. Adjust the supply airflow for a balanced
ventilation (small underpressure) during cooker hood
forced ventilation.
•
Balanced ventilation during cooker hood forced
ventilation can be verified in two different ways.
•
Measure the total extract airflow during cooker
hood boosted ventilation from the exhaust air
duct and compare this to the summed up supply
airflow.
•
If the cooker hood is equipped with a differential
pressure measuring connection, and a forced
ventilation airflow diagram is available, you can
use this to measure the cooker hood airflow
during forced ventilation. Add this airflow to the
airflow measured from the extract air terminal
devices during cooker hood forced ventilation.
This will then give you the total extract airflow
during cooker hood forced ventilation that can
be compared to the summed up supply airflow.
No basic ventilation airflow is allowed through the
cooker hood.
