3.3.3. Explanation for Indication
The optical display is located around the knob and is only visible when
switched on. In the pictures, the visual illumination in each specific case
is shown.
Green LEDs above (On/Speed):
The top row of LEDs in green shows the speed at which the ventilation
units are currently working. Here one LED lit up means the lowest fan
speed and five LEDs mean the highest fan speed. Thus, 5 different speed
levels can be set for your ventilation units. Turning the knob clockwise will
increase the fan speed. Rotating anti-clockwise, you will reduce the fan
speed.
Red LED down left (Off):
The red LED on the bottom left side means that the ventilation units are
turned off but the power is supplied to the control.
Blue LED downright (Ventilation):
The blue LED on the bottom right side shows that the unit is currently
working in the "Ventilation" operating mode.
This means that the devices connected to this control work without heat
recovery (fans operate without changing direction/reversing) and the air
led into the rooms has outside temperature.
Different LEDs are lit up simultaneously:
Simultaneously lit up LEDs for
speed (green)
and
ventilation (blue)
mean that the ventilation units are in the "Ventilation" operating mode
and work at the specified speed.
