Question 1

What do the lights on my Ictus ventilation unit mean?

Accepted Answer

LED 1:
Flashing green: Standard operating mode
Blue: Standard operating mode with direct supply of fresh outside air (natural cold function)
Orange: Standard operating mode with direct supply of fresh outside air (natural warm function)
White: Unit is in frost protection
LED2:
White*: Ventilation unit is connected to the internet and is connected to our system (application operation)
* Due to light pollution, the other LEDs may appear to have a different color when it is not on or give a pink glow when it is on.

LED3:
Green: Filters require maintenance, clean every 3 months and replace every 6-12 months
Pink: Power limitation is active, the device is still speeding up to the requested position
Blue: One of the temperature sensors measures abnormal values (possibly in very hot/cold weather)
Red: Emergency contact is interrupted
Yellow: Fan 1 is not running
White: Fan 2 is not running

Question 2

My ICTUS ventilation unit no longer responds to the RF switch, what now?

Accepted Answer

A) The remote control battery is empty. You can check this by checking whether a light lights up when a button is pressed. If no light is visible, the battery is empty. Battery to be replaced: CR2032 3V
B) The ICTUS ventilation unit is in frost protection mode. When it is around freezing temperature outside, the device can go into frost protection mode. You can recognize this by LED 1 that looks white. The ventilation unit does not accept control during this protection, to prevent damage. When it warms up again, the unit will automatically release itself from the protection mode.
C) Switch off the ICTUS ventilation unit by turning off the fuse, wait +/- 5 minutes and switch the fuse back on.

Question 3

What do the lights on my RF switch mean?

Accepted Answer

The RF transmitter transmits the status of the device when pressed and periodically (every 2-10 minutes):
Green: ICTUS device has received and processed the command (mode has changed)
White: ICTUS device has received and processed the command, but there is an emergency on the device (e.g. filters require maintenance)
Red: ICTUS device has not received the signal or has refused, this may be the case, for example, with frost protection.
If a red light is on but the unit does respond, this is a setting that was set on the ventilation unit during adjustment.
Red/green: The battery voltage is low and cannot guarantee that the signal can be sent. The battery needs to be replaced.
