Loudness of thermostatic heads

Hi, I’m new here so bare on me with my questions :slight_smile:

Recently I bought Max! set, which includes 2 thermostatic heads. For testing purposes I installed one of heads into my bedroom. What I found is that thermostatic head produces enough sound noise to wake me up in the middle of night.

So my question is what programmable thermostatic head do you suggest for bedroom? It’s a plus if it can be managed through Max! cube or OpenHab.

PS: Did you get across a comparison chart of those heads, which include data about loudness?

Thank you for suggestions!

Eurotronic Spirit is the same and in addition the algorithm of the thermostat is very poor. Most of the time it is to hot in the room.
