I changed in the living area and in the bathroom on the Honeywell valves, following the test result of the Stiftung Warentest. Unfortunately, Stiftung Warentest has escaped zeierlei what has now been performed here several times to exchange actions:
-While some regulators operate correctly, but others turn off randomly. Then you come into an overheated room - especially if you do not often use the energy saving is the hoped so then. What happens is that the device jumps in an unconfigured state, the valve fully opens and will be reprogrammed. Reasons? Unknown.
-The cheap metal tabs that allow the batteries to be mounted in the housing, are so soft and obviously little wertig that they give way over time. Say: the springs at the bottom of the battery door, press continuously the batteries with each a small metal tab that tired it and gives way. Here it takes is one millimeter, so that the contact is gone. This happens regularly and likes to about half a year.
Conclusion: For me the whole thing was an expensive experiment, there was critical reviews beforehand. Partial but based on this incorrect operation. But I have of the unreliability of the things the nose may be filled and if further break down, send it innerhab the warranty period and returned with the old, stable, thermostatic valves manual "downgrade" I've canceled thankfully.
That's really a shame because the concept is good. Ultimately it fails to Mies ester processing and billigster material choice.
Honeywell: I intended to transform saddled with successful use of Rondo deeds, in a few years on a radio-controlled system of your home. Since I do not believe that the "plumbers quality" makes a big difference to the "hardware store quality", I will refrain - and also from buying other products of your home.
