How to remove modules, etc?
 

I bought a used Profilux 4 and trying to remove everything and have factory default. It has in system extra powerbars; vortech controller etc and I dont have that. Is there away to clean everything out?

If you haven't already, download https://www.aquariumcomputer.com/sof...ontrol-center/ and install GHL's GHL Control Center (GCC)
This only runs on a PC, so if you have a MAC, you will need to run Boot Camp, Parallels, etc.
Connect your P4 via the USB cable. Under the system tab, you can delete the modules you don't have. I would suggest deleting them all.
Then up top, open the Devices tab, there you can reset defaults, and update the firmware.

Did you figure it out and does everything work?

Yes figured it out. However, my conductivity probe cant get calibrated. I dont think its a big deal but maybe I need new probe.
