The power section switch-on point can be adjusted to prevent humming noises in
stationary fans.
With a control variable of approx. 5 %, the modulation is switched from
“
0
”
to 15%. The
new control range is thus 15 - 100 % (Modulation

Peak load fans
The exhaust air is regulatedby the speedgovernor of the 1~ fan or the ETAvent.
Another fan (peak load) can be activated additionally in appropriately large stalls.

Attention!
Safety instruction for installation with peak load 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).
