Basic Z-Wave Tool is actually a driver you'll have to install yourself. You can use it to set (or view) Z-Wave parameter values if the "regular" driver you're using doesn't offer something you're looking for:
Its intended use is: temporarily change to this driver, then change back to the "regular" drive you want to use for that device.
If you do not change any other parameters besides the one in question here (I provided the information you'll need for it above, but all parameters are also documented in Inovelli's manual), then nothing else will change, and all the settings you saved in the Inovelli driver will remain. Again, I do suggested defying conventional advice and not clicking "Configure" when you change back to the Inovelli driver, lest it overwrite a parameter you changed with the Tool. (But really, the driver should do the same thing as this tool--Inovelli's driver exposes all parameters--so if it doesn't, then there's likely just a bug with it.)
