Heating not working although showing high temperature in control panel and app

Mudit

Hello
I am increasing the temperature on the app and also on the control panel, but it seems that the heating at home is not working.
Can anyone let me know how to reset the settings

Thanks in advance

How long has the system been installed?

What type of system do you have: Combi or System?

Do you have any pictures before and after installation?
