Hello,
One of the rooms on the ground floor of our house is clearly not being heated by our underfloor heating system. The thermostat and the actuator on the manifold both show activity. Before I contact a heating company, I wanted to ask for your advice to see if there might be something I can do myself.
Best regards,

Has everything worked properly over the past few months?
Unfortunately, I don’t see a flow indicator there.
Are you referring to the guest room?
Do all controllers respond to thermostat changes? Have you checked them individually?
At night or in the morning when it’s cold and the heating is on, you can check the supply and return flow of the individual heating circuits at the manifold by feeling them by hand.

At night or in the morning when it’s cold and the heating is on, you can check the supply and return flow of the individual heating circuits at the manifold (by hand touch). It probably hasn’t been working since the start of the winter season, but now I’m spending more time in that room.
Yes, exactly, the guest room is affected. Okay, I will check the manifold for flow then.
I would first test whether all ERRs are controlling the correct heating circuits (we had an issue with this as well).
So, set all ERRs to minimum first. After a few minutes, all the "plugs" will move down (in your photo, these are the gray parts with red on the side at the bottom).
Then, turn one thermostat fully up, wait a few minutes, and check if the correct plug moves up. Repeat this one by one for all ERRs.
This way, you can rule out this potential source of error.

You can see that the heating circuit valve for gas is closed on the controller.
According to Google, Roth controllers are NC, meaning they are closed without power, so the room is cold.
For example, your toilet/bathroom is likely quite cold as well.
Try turning the controller and observe if it moves; make sure the cables are not mixed up.
