Devices with two-room connection in the supply air:
The pressure loss of the connected channel in case of nominal volume flow (40 m³/h) must be known
for the setting of a balanced volume flow. A measurement of the volume flows is always required.
The fan speed is to be set according to the following table, whereby interim values are to be
interpolated:
•
Devices with two-room connection in the exhaust air:
The pressure loss of the connected channel in case of nominal volume flow (40 m³/h) must be known
for the setting of a balanced volume flow. The fan speed is to be set according to the following table,
whereby interim values are to be interpolated:

Devices with two-room connection supply air
and
in the exhaust air:
Combine the details according to the pressure losses of both the connected channels.
Servo Flaps
Parameters for the end position of the flap positions are assigned here. These parameters are
separately determined in the manufacturer plant for each device. An arbitrary change of these settings
can lead to functional impairments and/or to the deterioration of the flap mechanism.
Should these settings be modified by mistake then the EPP-covers above the ventilators are to be
carefully removed and all 4 possible parameters are to be set to the standard value “15”.
These settings are then to be transferred to the device control with the help of “Writing to the device”.
Switch the device to the fan speed 0 (flap position “closed”). The original setting, in which the effects of
the changed parameter can be optically checked, can be determined through careful modification of the
settings.
The flaps must rest lightly on the ventilator in the closed status. A setting, in which the flaps are
compressed from the Servomotor against the ventilator, is not permitted and must be absolutely avoided!
