operation together with a 

fireplace 

Pushing the key combination for at least 3 seconds deactivates the 

extract air mode permanently. This status is signalled by LEDs 

L8+L11+L12, where L8 and L12 are lit up, L11 blinks 2 times and 

then remains switched off. This signal is only visible when holding 

the key combination. Activating the extract air mode key in the 

deactivated state results in a short 3 time blinking of LED L11 to 

signal the deactivated state. Pushing the key combination again for 

at least 3 s cancels the key lock. This change is again signalled by 

the  LEDs  L8+L11+L12,  where  L8  and  L12  are  lit  up,  L11  blinks  2 

times and then remains switched on. This signal is only visible when 

holding the key combination. This enables the extract air mode 

again.

Setting keys  

The summer ventilation can only be implemented with 

an LED control panel if it has been released in the 

factory setting. 

Pushing the key combination for at least 3 seconds activates the 

setting for the temperature limit. This status is signalled by the 

blinking of LEDs L8 and L10. With the setting keys the upper 

temperature limit for summer ventilation depending on the extract air 

temperature can be set between 21 °C (LED L1 lights up) and 27 °C 

(LED L7 lights up). After pressing the key combination again for at 

least 3 s the setting is saved and the summer ventilation 

temperature limit is terminated. 

Always press the reset filter replacement key first!

Keys 

for setting the balance 

By pushing the key combination for at least 3s, the imbalance 

configuration mode is activated and the LEDs L10 and L12 blink. 

The keys for setting the balance can now be used to set the balance 

of the fan speeds active upon activation of the imbalance 

configuration mode in 5% increments. The balance is not set for 

each fan speed individually, but jointly for a group of fan speeds. 

The adjustable range is between -

15% (L1) and +15% (L7). In the 

central position (L4) the supply air and extract air run with the same 

rotational speed. After pressing the key combination again,  the 

setting is saved and the imbalance configuration mode concluded. 

Always press the reset filter replacement key first!
