cover 

14.1 Settings on electronic circuit 

boards 

 

Notes

 

●  Electronic circuit boards [12] of the ER 

variants standard EVZ, EG and EH have 

no setting options. 

●  Electronic circuit boards [4] of the ER 

variant H are equipped with an automatic 

humidity function. For unit functions 

 

chap. 7.3.3. 

●  Tolerance for time details max. + 20 %. 
●  Units with a time delay switch (EVZ and 

EH fans) have resistance to interference in 

line with EN 55014-2 (depending on pulse 

form and energy factor 1000 to 4000 V). 

These values can be exceeded when ope-

rating with fluorescent tubes. In this case, 

additional interference suppression mea-

sures (L, C components or RC module, 

protection diodes, varistors) are required. 

Setting 

1.  Place fan insert on front so that electronic 

circuit board [4] (control) is freely acces-

sible. 

2.  Set the desired values as follows with the 

potentiometers or jumpers.

 

 

Electronic circuit boards ER 60 EH and  

ER 100 EH 
Humidity control function on EH units 

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 relative humidity 

falls

 below the 

reference value during operation, the newly 

established reference value is saved.  

If the room humidity 

increases

 by 10 % 

within 2 minutes, the fan automatically 

switches to the nominal load level (60 or  

100 m³/h). 

If there are no further increases, the unit 

continues to run at nominal load level 1 until 

the humidity again falls below the saved 

reference value. 
If the humidity falls below the saved reference 

value, the overrun operation starts with an 

overrun time of 15 minutes.  
If the humidity 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.  

ER EH units

 can also be operated using the 

light switch. With “Light on”, the fan starts in 

nominal load. Actuation via the light switch 

takes priority over the automatic humidity 

function. With “Light off”, the unit continues  

to run until the remaining overrun time has 

passed. The automatic humidity process is 

then assigned maximum priority again and 

controls the unit. 

 

14.2 Installing fan insert 

 Fig. 11

 

The ER fan insert is inserted into the ER-

UP/GH recess-mounted housing as follows.  
1.  Switch off mains fuse, secure and fit 

warning sign. 

2.  Remove plaster protective cover [38] and 

clean any dirt off the recess-mounted 

housing. 

3.  Ensure that the fan type ticked in the 

housing box matches the type to be fitted. 
Check ease of movement of backflow 

preventer. When installed, the backflow 

preventer must close automatically.  

4.  Check that the housing floor seal is 

correctly positioned and insert properly. 

 

NOTICE 

The noise level will increase if the 

housing floor seal [5] is fitted 

incorrectly. 

Degree of protection not guaranteed if 

housing floor seal is positioned 

incorrectly.  

 The housing floor seal must lie flat and 

without any creases in the housing.
