I bought two of these automatic thermostats me a few weeks ago. The installation went quick and easy. The programming is also carried comfortably, the enclosed instructions for quick understanding perfectly adequate. The look and feel of the thermostats are very good, especially when you consider the reasonable price. The volume in the automatic rules is acceptable. In the bedroom, but I would probably not install this device more. Slightly irritating I found at the beginning, that it always takes some time until a setting (eg. Manual increase in temperature) will be implemented. This means that the thermostat does not respond immediately, but sometimes only a minute later. But it's when you know that no problem. Useful functions such as the vacation mode and the automatic window-On Detection. I highly recommend this device. It is simply super, finally in a rented apartment, with no possibility to access the heating system, to come into a warm living room after work!
