Before you can mount tado° onto your radiator, you will have to remove the existing radiator thermostat head. Unmounting depends on the type of radiator head.

In some cases, additional tools such as spanners or screwdrivers might be needed in order to remove the existing radiator head from the valve. You may need to check with the manufacturer if you are unsure.

If you don’t have the necessary tools, you can also, for example, use a towel to unmount the screw nut. Some radiator thermostats need to first be fully open in order to be unmounted.

During the installation process once you’ve unmounted the old radiator thermostat, before mounting the Smart Radiator Thermostat, the radiator will heat up because the valve is fully open. This is completely normal. The Smart Radiator Thermostat will close the valve once you mount it.

Unmounting depends on the type of radiator head:

Option 1

Some of the thermostatic heads can simply be unscrewed from the valve body. Be careful to open the head screw nut and not to turn the full head which will unscrew the valve fitting itself.

Option 2

When you see that the head is fitted by a screw, please remove that one first and then pull off the thermostatic head to the front.

Option 3

A few thermostatic radiator heads are removed by turning the head beyond the maximum temperature setting. Be careful to only unscrew the head and not the valve fitting itself.

Option 4

If none of the above seems to fit your thermostatic radiator head, try simply pulling the head off. For those cases, the head usually consists of two parts and you will have to remove the component beneath to which the head itself had been mounted.

Option 5

Standard Giacomini thermostats consist of two parts. To remove the thermostat head, firmly hold the bottom part near the valve and pull outward, then also pull the top part in the direction shown. You will hear a click and the whole thermostat head will come off easily.
