2.2.1 Supply and Extract air Fans
The fans have external rotor motors of EC type which are steplessly controlled individually by setting the control signal
to a fixed value. It is possible to program the speed in 2 steps (normal/reduced) depending on the programming of the
week schedule. The motor bearings are life time lubricated and maintenance free. It is possible to remove the fans for
cleaning, see chapter 5 for more information.
