How to switch on or off the radiator
GENTLY turn the button to the right, the number on the button will show and rise, turn until it displays the desired temperature.
Give the knob some time to adjust, its electronically, not mechanically and it need sto communicate with the server. Handle it with softness as it is electronical material and more delicate as a mechanical nob.
It will make a zooming sound and the radiator will turn on.

How the heating system works
Please note that:
- The heating does not turn on automatically unless the room temperature drops below 16°C
- When the heating is switched on, it is configured to automatically return to 16°C after 2 hours, to avoid unnecessary heating if it is forgotten on
In a small studio, this is usually sufficient to warm the room and keep it comfortable for some time. You can then turn it back on when needed.
A common misunderstanding is that setting the thermostat to 23°C or 25°C will heat the room faster.
This is not the case — it only means the heating will continue running until that higher temperature is reached, which can lead to unnecessary energy consumption and costs.
If you think your raditor doesn’t work
To be sure, we kindly ask you to do the following test:
The radiator does not switch off
- Turn the heating off
- After 3 hours, check if the radiator is still warm
The radiator does not switch on
- Turn the heating on to 25°
- After 30 min check if the radiator is warm
- If the radiator is NOT warm, this may be due to
If it is, this usually means the batteries are too weak to fully close the valve, which can cause irregular heating behavior.
