General solution: Dirty filter notification via wired connection
What do you need?
Niko requirements
Your Niko Home Control installation meets the following requirements:
It has a connected controller II.
It is configured with the most recent programming software.
You need the following connections and additional products:
Install and connect a digital potential-free sensor module (550-00210).
If the output contact on your ventilation system is not potential-free, you need an additional potential-free contact module.
Third party system requirements
Your system meets the following requirements:
Your ventilation device has an output contact that signals when the filter is dirty.
It is compatible with the Niko module (see Niko requirements).
Please note that not all ventilation systems that you can control via Niko Home Control are equipped with the output contact required for the filter notifications.
Wiring diagrams
Via potential-free output contact
The output contacts of most ventilation systems are potential-free, allowing a direct connection to the Niko sensor module.
Connect contact 1 on the Niko sensor module to the output on the ventilation system that signals when the filter is dirty, as shown in the wiring diagram.
Via 230 V or 12/24 V output contact
If the contacts of your ventilation system are not potential-free, you additionally need an appropriate potential-free contact module.
Connect contact 1 on the Niko sensor module to the output on the ventilation system that signals when the filter is dirty, as shown in the wiring diagram.
230 V output contact | 12/24 V output contact |
|---|---|
 *230 V to potential-free contact module (e.g. Finder 22.32.0.230.1xx0) |  *12 V to potential-free contact module (e.g. Finder 22.32.0.012.1xx0) or 24 V to potential-free contact module (e.g. Finder 22.32.0.024.1xx0) |
Programming
Configure the potential-free sensor module and create an informative notification via the Niko Home Control programming software. For more information, see https://guide.niko.eu/en/smnhc2/lv/creating-notifications.
