Variant 3:
Two regulated groups with different amounts 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. When the connection point
of group 2 is reached, the group 1 holds the speed.
The second(smaller) group switches on andis slowly
turnedup.
Following settings are without function:
- Group1 100 %
- Off group2
- Minimum2

Variant 2 (example with 4 groups)
Group 1 (power unit) is a regulatedfan group, group 2,3 4 and4 are unregulatedandoperateddirectly on the mains. The group
control is performedby the “ master ” but because this does not have enough free relay outputs, 2 relays of “ slave ” units are
used.
In the “ IO Setup ” the functions which are executeddirectly by the “ master ” are programmed. The functions which are distributed
to the “ slave ” units must be set on the “ master ” under “ Bus ” .

Group 1 behaves in such a way that its speedrises constantly until the switch-on point of group 2 On reaching the connection
point for group 2 its relay switches on andthe speedof the  rst group is reduced to an adjustable “ Minimum2 ” .
If the ventilation requirement increases further, the speedof the  rst groups rises again to “ 100 % ” , then the group 3 is
connectedandthe  rst group is reduced to “ Minimum3 ” . andso on.
