The fans are variable speed controllable by means of a 0-10 V control voltage. Suitable potentiometers (type PU/A 10),
three-step switches (type SU/A) are available in the Helios accessory range. Variable speed control is possible with a
universal control system (type EUR EC). Alternatively, the electronic differential pressure/temperature controller EDR /
ETR can be used.

Activation / deactivation:
EC fans can be frequently activated and deactivated via the 0-10 V control input or the release input
depending on the type . This is gentle on the electronics and ensures a long service life . Control via the
power supply (on/off) is not recommended . In general, there must be an interval of at least 120 seconds
between activation and deactivation .

In case of strong vibrations and/or noises, maintenance must be carried out by a specialist according to
chapter 1 .4 .
