Reactor dimmer knx

I have to connect a thermal sensor ntc10k on reactor
 where to connect and how to configure?

Thanks

You device has a 1-Wire port so you can use ds18b20 sensor instead.

For NTC sensors you need an additional resistor to create a voltage divider. It should be connected like this:
GND -- 10k fixed resistor -- I/O port -- NTC 10k sensor -- 24V

Then you will need a script to calculate sensor resistance based on the I/O port voltage and convert resistance to temperature using a look-up table. The resulting accuracy might be quite low.
