NOTE
Roof fans – RD/VD EC
3�2 Mounting
The roof fans are designed for base installation. The base plate of the fan has 4 holes for mounting to the base. Place
the fan with the base plate on the base (see Accessories). In this respect, observe the respective installation and ope-
rating instructions for flat roof bases. Tighten the anchor screws equally to avoid warping.

Stepless speed control is possible with the universal controller (Type EUR EC). Alternatively, the electronic differential
pressure/temperature controller EDR / ETR can be used.

Activation / deactivation:
Frequent switching on and off of EC fans can be carried out via the 0-10 V control input by switching off the control
signal to 0 V. This applies to operation with an external potentiometer or external 0-10 V signal from the building
management system. Switching off is alternatively also possible via a release input, depending on the type. This is
gentle on the electronics and ensures a long service life. If this is not easy to realise, e.g. when operating with an
internal potentiometer, it can also be done by switching off the mains supply. In general, a time interval of at least
120 seconds must be observed when switching the mains off/on.
