Hi, we all have to start somewhere, yes you will need a custom device type to set the options, I have taken a look at the manual here and can see the options.
I am not a coder either but I have knocked you up a custom device type that should work
to install this just goto your Smartthings device handlers page here if you are in the US or here if you are in the UK and then click on
then choose the from code tab and paste in the code from my github page above and then click on Create
you will see near the bottom of the code the resetParams2StDefaults() section, this contains all the parameters from the manual that are currently set to the default options
for example below for parameter number 1, the default value is 3, just change any of the parameters values between the for the desired value as per the manual,
cmds << zwave.configurationV1.configurationSet(configurationValue: [3], parameterNumber: 1, size: 1).format()
once you have finished then just click on the set location on the right of the page
then select your popp device from the dropdown and click install 
then all you then need to do is put the Popp device into inclusion mode by triple clicking the button and then click on the resetParams2StDefaults button as highlighted below
once the device comes out of inclusion it should have the configuration, however i have also included the listCurrentParams button, which you can click once you’ve put the device back into inclusion and the device will list its current configuration in the log window.
word of warning,dont be tempted to set the parameters and try to list the parameters in the same inclusion cycle as it takes a while to send all the commands and you will cause the device to not process all the commands in the inclusion time window
hope this helps you out. however be aware that i do not currently have one of those devices to test against, this has been written solely based on the manual and the default Smartthings Dimmer code.
regards
