This community was set up several years ago so that customers using the Samsung smartthings home automation platform could help other customers. It’s not an official support channel and it’s not the aeotec support forum. So in the future, if you run into a problem with an Aeotec device, you might want to check with their support.
That said, this is a frequently asked question here, so as it happens, we were just talking about it a day or two ago. 
So here you go, it’s the same answer for your device. You will get to the fields through the smartthings app and you will be able to change the values there. But there may be a couple of steps you have to do first.
