The children's room is too warm in the new building.

Hello everyone,

we have finally been living in our new building for 2 weeks. We have underfloor heating throughout the entire house and a digital thermostat in every room. All thermostats in the entire house are set to 21 degrees. It also works without any problems throughout the house. As soon as the thermostats reach 22 degrees, they switch off. Except in the children's room. There we have noticed that the temperature comfortably reaches 23 degrees overnight and the floor in that room is constantly warm compared to the other rooms.

I have already contacted the company that installed everything for us, but it will probably take some time before I get a response. As a curious person, however, I would very much like to know what could be the reason or what the cause could be.

Regards

Check the flow meter in the distributor, is it open? Actuator defective? Flow too high?

As far as I can see, the pen goes down or up each time the thermostat opens or closes. The flow looks the same at first glance in all the rooms above.

Circuits in the distributor labeled incorrectly and thermostat connected to the wrong circuit?

Actuator defective or jammed. You can try turning all rooms fully up at the room thermostat and the children's room fully down. It should be traceable again at the manifold.

Circuits mislabeled in the distributor and thermostat connected to the wrong circuit?

I suspected that too. But yesterday I turned off all the thermostats upstairs except for the children's room. However, the temperature only rose in the children's room and in no other.

But all rooms are heating up even though the floor doesn’t get properly warm. Only in the children's room does the floor get nicely warm.
