When heating a room, open valve in steps

Brantdk

When Tado heats up a room for example from 18c to 20c, it´s all or nothing. Because the valve is open all the way, it make a hissing noise. What if it opens in steps? That would minimize the noise coming through the valve.

It´s not tado that is is causing the noise, but the valve being open full to reach the Temputure all at once

The valve does open in steps. Are you sure the hissing noise isn’t caused by it opening too little and forcing the water through at high pressure? Either way you might be able to solve it by balancing your radiators or asking Tado support to change the amount the valve opens.
