Have you tried the following option;
You can find it under “Preferences”
Cheers, I had been trying that but it didn't seem to work, as well as the IO switching in the config.
I used basic zwave tool and confirmed that the config was not being altered. I removed the device, reset it and readded and the reversal switch now works but I still couldn't change the S1/2 parameter, I had to use zwave tool but its all working now.
Great! Glad to know that it’s working now.
As I use to say, the most important device in a computerized system is the power switch … 
Thank you very very very much for this instructions! I wasted some hours to include the device. Then I've read each post about it and finally I've found your procedure: it worked! Thanks!
