Settings in the exhaust air system are necessary in
single exhaust air systems with more than one
additional group
(peak load function is not enough) or
in central exhaust air systems
.
The total exhaust air is regulated by one or more 1~ fans or ETAvent fans. In accordingly large stalls
or in a central exhaust air system another regulated fan or up to four unregulated asynchronous fans
(in groups) can be connected.

Factory setting Exhaust mode switched off
= OFF (no Grop control)
To activate the exhaust air mode, this must be set to:

1. two regulated fans (groups) of the same size:
- fan 1 (group 1) directly by the regulator
- fan 2 (group 2) e.g. via 0 - 10 V output 1 and additional power unit
2. one regulated fan e.g. directly by the regulator and max. four other unregulated
groups (connected via relays)
3. two regulated fans (groups) of different sizes:
- fan 1 (group 1) directly by the regulator
- fan 2 (group 2) e.g. via 0 - 10 V output 1 and additional power unit

number of groups of which the ventilation system consists
•
In variant 1+3 (with 0 - 10V control) max. 2 groups. Settings by

possible, (are
ignored by the device, corresponds to number of 2 groups).
•
In variant 2 (relay control) max. 5 groups
Setting range: 2 - 3 - 4 - 5
Factory setting: 2
Group1 100%

Switch-on value (related to the total air volume of the system) or value at which group 1
is operated with maximum control.
Useful in connection with a heat exchanger. Here, you can have the fan group
