Group control variants
The fan groups 2 to 5 (maximum) can be distributed to the free relays of all existing devices in the
system (the free group relays of the devices should be used preferably for groups 2 to 5).
If other, free relays are usedfor group fans, several groups can be connectedto one device.
Information
The settings of the group variants, number of groups andconnection points are made in a central
exhaust air system on the
“
master
”
device only if IO (inputs and outputs) of other devices have to be
used.
Five fan groups can be implementedwith the group function. There are different variants for the
different compositions of the groups, e.g. one regulated and one unregulated fan, which can be
selectedin the Group Variant menu.
Attention!
Safety instruction for installation with group fans. Shutters and similar should generally be
connected so that the shutters open in the event of a power failure or cable break insofar as
these have an emergency function (e.g. spring recoil).
Group variant OFF: parallel operation
The simplest variant is the parallel operation of several fans. In devices with power unit several fans
can be connected in parallel depending on the reference current of the device and the fans ( motor
connection).
In parallel operation of ETAvent fans, several fans can be connected at one regulator output depend-
ing on the type (PWM or 0 - 10V) ( connection ETAvent fan).
Variant 1 and variant 3 control second group via 0 -
10 V signal output
Example: Control group2 via 0 - 10 V output

Variant 1:
Two regulated groups with the same amount of air
This variant provides for an increase in speed of group
1 (on the regulator) up to a percentage (switch-on
point) of the control range.
Then group 1 andgroup 2 (output 0 - 10 V) are set to a
value at which both fans convey about the same vol-
ume of air as the
rst group alone previously (min. 2).
From here on both groups run parallel at maximum
power.
