Hello all!
First post, and I hope a post in english is ok here. My name is Thorsten and I live in the north of Sweden.
I have a Fröling S4 turbo 60, from somewhere around 2014-2015, that after a power off using the main switch due to some maintenance, doesn't start the touch display anymore.
The boiler powers up, and the display also starts to boot, but it just stops at a startup image, and the status light remains red. Please see attached image.
The boiler seems to run in some kind of emergancy mode when used, where overheat protection is enabled and the pumps run by the hydraulic module seems to run at some extent.
I have tried rebooting. I have tried changing cable from the main board to the display.
I have tried to connect the rj45 (network tp cable) output from the display, to a router to see if any dhcp request attempts were logged, but I could not see the display connecting.
Has anyone seen this issue before? Any ideas what I can try next?
Answers in german are totally ok. I'll just use google translate.
Thank you
best regards
Thorsten
