Device would have been ansich really great, but does not fit as described for Oventrop thermostats! But is on the radiator thermostat Oventrop is a fine thread, supplied completely different Thread. Do not see the adapters available. Then one tries to screw this unit and start the plastic threads on this thermostat is messed up and broken. Buy better when Heizungsmonteur, it certainly fits well. Hab returned everything, never again !!!
