ᐅ How to Tell if the Underfloor Heating Is Operating – ERR Still Without Thermostat Cover

Hello. We have the feeling that the underfloor heating is running in one room of our new build. The room isn’t really hot, but the air feels like it does in winter when the heating is on. The floor is also not as cold as in the other rooms. Our room temperature sensors (RTS) are not installed yet. So far, only the thermostats themselves are fitted, but the covers for adjusting them are still missing. The electrician unfortunately delivered the wrong ones here. I have already turned the controller to the left with a screwdriver. However, I could keep doing this indefinitely. I can’t tell when it reaches zero. If I go too far, it goes back to 6. There has been a slight improvement in the room air quality, but the heating could still be running there. I should be able to check at the manifold boxes whether and in which circuit there is movement, right? But how? All the manifold valves are set to automatic. If the heating is firing, it could actually be heating. I seem to remember that ELCO customer service set the heating to activate only below an outside temperature of 18°C (64°F). Thinking about it, isn’t that quite high for a new build? If the outside temperature is 18°C (64°F) for 1 or 2 days, I shouldn’t really notice anything inside, right? What do you think?

This way, you can start adjusting settings right at the beginning of the heating season instead of having to learn about it later. There is a pink forum that focuses on building services engineering in dialogue, where you can find good information and support. You don’t want the heat pump to be prematurely worn out after 5 years due to improper cycling...

The heating limit of 18°C (64°F) is quite high for a new build. Have you achieved the KfW standard?
And what supply and return temperatures does the heat pump indicate?

We installed an air-to-water heat pump. Elco Aerotop Slit 07M-R.
I will check the supply and return temperatures later.
Our insulation meets the KfW 40 standard. We are only missing a bit of additional technology to fully comply with KfW 40 overall. However, KfW funding was not really worthwhile for us anyway in terms of conditions.

Oh, and something else just came to mind. I had two heat meters installed in our system: one in the underfloor heating circuit and one in the domestic hot water circuit. Both show flow volumes. That means the underfloor heating must be running somewhere, right? The installation on the underfloor heating circuit took place only after the hydraulic balancing. During that process, I was also shown how to set the controllers on the manifold when operating through the ERR.
Here are the pictures of the distributor box upstairs. This also relates to the bathroom upstairs. The float is positioned differently from the others. What does this mean? I would say the pipe is also slightly warmer than the others. According to the heating system, however, it is currently 21°C (70°F) outside.
Regarding the flow temperature, I can't find a display. I can adjust it on the heat pump, but only by a bar scale of about ±7°C (±12.6°F). The actual temperature itself is not shown to me. Shouldn't there be a display on the pipes?
