Switching on
The unit starts up approx. 50 seconds after
switching on the room lighting with switch S1.
Switch S2 is closed.
Switching off, scenario 1
The unit has an overrun time of approximately 6
minutes after switching off with switch S1 (room
lighting) and then switches off.
Switching off, scenario 2
The unit can be switched off directly with switch
S2, i.e. regardless of the room lighting.
Function of the H model
Once the fan insert has been installed, the unit
regulates to the current room humidity (relative
humidity). This humidity value is saved as the first
reference value. The reference value does not
have to be specified manually.
If the room humidity increases by 7 % within 2
minutes, the fan automatically switches to the
nominal load level (60 m³/h or 100 m³/h). The unit
continues to run at nominal load level until the
stored reference value is undercut again.
If the humidity falls below the saved reference
value, the overrun operation starts with an over-
run time of 15 minutes (nominal load) If the hu-
midity does not fall below the reference value
within 60 minutes, the unit switches back into the
operating status before the humidity control was
activated. The current humidity value is saved as
the new reference value.
If the relative humidity falls below the reference
value during operation, the newly established ref-
erence value is saved. ER ...H fans can also be
operated using the light switch.
With “Light on”, the fan starts in nominal load. Ac-
tuation via the light switch takes priority over the
automatic humidity function. With “Light off”, the
unit continues to run until the remaining overrun
time (15 minutes) has passed. The automatic hu-
midity function is then assigned maximum priority
again and controls the unit.
