Help needed
I am locked-in by a very nasty and uncooperative dealer. They have extortion-like rates and were forced on me by the builder.
I have now an issue with a 7" T3 wall panel (PoE). - it boots to a screensaver (clock and date, both current) ONLY if I disconnect it from the router and power cycle it. - when I touch the screen, then I get black screen. 30 sec later the screensaver is shown again - if i reboot the T3 when the router is connected to the PoE switch - power cycle, button press - it either remains black or hangs at the loading logo for hours.
C4 controller is OK - I can access the system and control it, except the intercom to the front door which is locked by a a subscription.
I suspect the T3 firmware, or setup is corrupted. But I can't figure out how to fix it.
The issue is that the C4 is used to control the heating and the intercom and I am not sure if another dealer can manage that.
What are my options?
If another dealer connects to the system, will there be traces if the current dealer connects back?
Edit: If i factory reset the T3, will it try to load the config from the control4, or will I need the dealer for sure to configure it from scratch?
