Does this help?

Are these radiators or underfloor heating? If radiators, do they have their own thermostat? If a thermostat is present, I would simply replace it with programmable ones.

By the way, wasn’t it said at some point that night setback even causes increased consumption?

These are radiators from 1995. Without a thermostat. According to the installer, this is not possible on these radiators either.

Did the defective control (thermostat) look like this?



From the boiler's user manual:

....If no remote control is connected, you can set your room temperature for normal heating operation (day operation) and reduced heating operation (night operation) on the control unit. If two heating circuits without remote control are connected, the settings on the control unit apply to both heating circuits...

As expected, settings on the heating device are indeed possible, even without a room temperature controller.

No, the thermostat looks different.

It says Buderus Ecomat 4000 on it and you can press different buttons. This device was hanging on the wall here and a cable goes to the wall. But the device was dead and at the bottom you can clip it into this blue control box, but nothing happened. Therefore, as I understood the technician, you cannot change anything anymore.

I will send my husband down to the basement again later with this picture. I just went down again and wouldn’t know where to adjust that on the boiler?

And we only have one heating circuit.

But if it were possible there somehow, you should be able to set the time and temperature?

This is probably a really stupid question, but you certainly can’t retrofit a separate heating circuit, can you? Or only for an extremely high amount of money?

Our tenant lives in the basement. It will always be cooler down there anyway, even at 4:30 a.m. in the summer...

but you surely can't retrofit a separate heating circuit, can you? Or only for an extremely large amount of money?

It depends on how the system is configured now (I mean which pipes run where). But as a rule, separating by floors is possible without any problems.

So you then had this here:
