And what's the steel wire attaching to the box? the box looks completely empty but given the color fading it looks like it comes with the radiator itself, not something previous owners added

What are these for? Are they the recommended level in apartment buildings? In living room and kitchen it's between 1 and 2 but in bedrooms between 2 and 3. But aren't we supposed to turn heating to max?

Re: red arrows on radiator control
The small box and "wire" are the temperature sensor and a capillary tube with liquid inside. Do not cut the tube or bend it sharply because the liquid will escape and the thermostat will be useless.
This kind of radiator thermostat is used when there is furniture in front of the radiator and the valve itself would not register the real temperature of the room because heat would be trapped by the furniture and affect the temp reading. You are supposed to fix the box on the wall away from the valve where it can read the room temperature better.
Things go wrong if you let the box get too close to the radiator, dangle over the warm pipes or dangle loose and have the tube fracture due to mechanical stress (I think you score on several of these points).
The triangles - the manual for the valve will explain.

The box is empty. So it's already broken??riku2 wrote: ↑Sun Jun 23, 2024 10:18 amThe small box and "wire" are the temperature sensor and a capillary tube with liquid inside. Do not cut the tube or bend it sharply because the liquid will escape and the thermostat will be useless.

I have never seen any manual here
Re: red arrows on radiator control
is the box really empty? there is normally a small metal cylinder with the liquid inside. if the wire just ends inside the box then the valve cannot monitor the temperature.
the manual - the company is called "danfoss". they will have a website. there will be manuals on their website explaining their products. although you probably don't know the model number the website will have pictures of the different models of valve. The concepts will anyway we similar and the red triangles will be explained in one/more manuals.
the manual will also explain how to remove the valve when decorating - something I assume the previous owner didn't know how to do, hence the red paint on the valve.

Re: red arrows on radiator control
Yep it's empty. It's a white box wrapping a black box and there is nothing inside except for the wire.
can't find model name for the thermostat. It looks ancient. Thanks anyway!

Re: red arrows on radiator control
I have a different Danfoss model with similar arrows. They are used as guides for configuring the range of temperatures (by physically limiting how much it can spin). There should be a couple of removable plastic bits that you can place in different little holes around the thermostat. You would use the arrows to know where to place them.
