3�4 Functional description
The Roof fans RD/VD EC are steplessly speed-controllable by means of 0-10 V control voltage. The devices are supplied
as standard with an internal potentiometer for setting of control voltage allowing speed to be set between min. and max.
speed. For an external speed setting with a 0-10 V control signal, the internal potentiometer must be removed.Suitable po-
tentiometers (Type PU/A 10), three-step switches (Type SU/A) are offered in the Helios accessories range.
Stepless speed control is possible with the universal controller (Type EUR EC). Alternatively, the electronic differential
pressure/temperature controller EDR / ETR can be used.
