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) |
