This temperature station is the 2. What we have. The first was delivered the same defect, but also impeccably converted in the usual manner through Amazon, thank you. The base station provides real-significantly better than on the product image (high-gloss plastic with chrome trim), except the outdoor sensor, this is from a normal matte plastic. However, this does not interfere further since selbiger is anyway mounted outside. Although this is called a remote sensor as is but explicit reference in the description of the manufacturer on which it should be installed in a sheltered, dry place. And that already revealed the first problem of this station. The range of the transmitter, the station is indeed given as 100m, however only in clear line of sight between transmitter and receiver. We have hollow brick walls and there is already at 2 walls fit with the radio reception between the transmitter and station. The transmitter also has a low battery warning. A warning icon appears if battery capacity the display of the external station. Otherwise, this temperature station performs its service as it should be. Display (size of the numbers on the display approx 12mm) is the interior temperature and associated humidity and outdoor temperature with humidity respectively. Similarly, the current min. And max. Values (size of figures about 6 mm) of temperature and humidity display. The temperature display can be switched from Celsius to Fahrenheit. There is also a graphical representation of the comfort temperature range whose sense to me, however, escapes, as cold and heat sensation always differs from person to person. Is my cold I turn the heater on and vice versa, no matter what a feel-good display correctly, but no matter. I give here only represents my opinion. Furthermore, the current time (Size 12mm) and the current date (Size approximately 6mm) appears on the display of the base station yet. This data is transmitted via radio clock. The functional yet further includes the possibility of a time interrupt ala Funkwecker. The so-called "meme" - key (memory) allows you to retrieve or delete various data such as min / max values of temperature and humidity, or to specify the time recording memory of this data over a specific period. There is also the possibility of an alarm, depending on your taste, adjust accordingly for excessively high or low outside temperature. One more thing on the operation of the base station. Lighting, alarm on / off and memory fetches (Memory) can be made easily accessible via the external Base Station keys. To reset (reset of the device), a wireless signal search, alarm settings, manual time / date settings or the temperature unit range from Celsius to switch to Fahrenheit / adjust the cover on the back of the base station must be opened in order to achieve the appropriate control buttons. This cover can pretty smoothly up or be delivered postponed. For someone who is constantly the alarm data will change the fact the then permanent opening and closing may prove annoying. To get an overview about prevailing temperatures even in low light conditions or when it is dark, the base station at the top of a large, well-to-use button, with which for about 5 seconds, the display can be greenish illuminated. Ultimately, however, it is sufficient to just only 3 stars. One star deduction for the transmitter (which indeed must be protected from direct sunlight and moisture) which is actually none and be able to make the second star deduction for the somewhat cumbersome operation to settings (cover back). Thank you for reading this review.
