Started last year in order to replace the old and defective thermostats from. Initial successes are already visible and it's really awesome. Installation is easy suuuuuper !!! Settings, functionality and Co are really for everyone no problem. However, I have to deduct a star from my two delivered products is a very loud, the other, barely noticeable. So I can not use in the bedroom. The function is missing "window". But for the price, a highly recommended product!
