5. Operating the fan
Operating the fan
ER EC fans run at 30 m³/h in base load
operation (factory setting).
A light switch or separate switch can be used
to switch to full load operation with 60 m³/h.
The fan control and operating unit are located
in the cover: ER-AK, ER-AH and ER-AB have
automatic functions with unit parameters that
can be set chapter 11.
● ER-A: Standard model
● ER-AK: Comfort model
● ER-AH: Model with humidity control,
barrier-free
● ER-AB: Model with motion sensor, barrier-
free
For full load operation, a start delay of
60 seconds and an overrun time of
15 minutes are specified at the factory.
The factory settings meet DIN
18017-3. If the setting parameters in
operation with cover ER-AK, ER-AH
or ER-AB change, function in
accordance with DIN 18017-3 is not
always ensured. The planer/installer
is responsible for operation in
accordance with standards.
In the event of overload (blocking),
the fan switches off automatically.
Ensure sufficient supply air during
operation.
