6.  Malfunctions

In the event of a malfunction:

�  

the LED light on the unit flashes;

�  

the display on the unit shows the corresponding 
malfunction code(s);

�  

the operating device can show a message. The 
manual of the operating device contains more 
information about the indication method.

The power to the unit should not be disconnected 
unless the unit is to be taken out of service due to a 
serious malfunction or any other compelling reasons. 

 Do not disconnect the power of the unit, unless 

told otherwise in the manual of the unit. This 
can lead to a build-up of moisture and results in 
problems with mould.

 When the unit is installed in an area with a higher 

average humidity (such as bathroom or wc) 
the probability of condensation on the outside 
of the unit is high. This is almost the same as 
condensation on a window, on which no action is 
needed.

In the event of a filter malfunction, replace the filter 
as described in the maintenance chapter. 

In the event of all other malfunctions follow these 
steps:
1.  Navigate to RESET ERROR.
2.  Select CONFIRM.
3.  Wait for 5 minutes.

If the error reoccurs:
4.  Navigate to STATUS.
5.  Navigate to CURRENT ERRORS.
6.  Write down all the malfunction code(s) (Select 

NEXT to view more errors).

7.  Select BACK.
8.  Navigate to UNIT
9.  Navigate to HRU TYPE.
10. Write down the unit type.
11. Close the visor.
12. Contact the installer or service engineer and give 

him the noted information.
