The fan is switched manually to full load operation
with switch "S1". Humidity control is active. After
switching off with "S1", the fan continues in full
load operation for an overrun time of 6 minutes. If
after this time, the humidity as measured at the
fan
• is higher than the switch-off point, the fan con-
tinues to run in full load operation until the hu-
midity drops below the switch-off point. Only
then does the fan switch off automatically.
• is lower than the switch-off point, the fan imme-
diately switches itself off automatically.
If switch S1 is open, the fan can start up automat-
ically as a result of high room humidity.

With switch S2
, the fan can also be switched
off independently of the room lighting in the event
of malfunctions caused by reverse polarity
voltages, for example.
ER 60 G, ER 100 G
The ER 60 G and/or the ER 100 G can be oper-
ated in base or full load operation as required.
S1
Switch for base load operation: Continuous
operation at a lower speed with lower air volume.
S2
Switch for full load operation and room light-
ing: When the room is being used, the unit can be
switched to high speed with full volumetric flow.
ER 60 GVZ, ER 100 GVZ
Standard switching:
Fan always runs at base load. When the room is
in use (S1=On), the fan switches automatically to
full load after approx. 50 seconds.
