The majority of our energy needs in our family house is controlled by the central control of the heating system and the separately controllable heating circuits of floor heating. A few rooms are on the other hand equipped with a standard radiator, which is why there is, especially in winter in these areas increased attention needs to not sit shivering in an emergency in a the cooled corner of each room. And even if hot water bottle and blanket in recent years have become cherished companions - really comfortable and practical hand-operated heating mode really is not. From unavoidable energy losses quite apart.
Lange has retained my skeptical about automated thermostat the upper hand over reason before the harmless winter should let me 2013/2014 reckless for subjects with these universal devices of Heizlux be. Supported by persistent nagging admitted by my wife, as much is. Lo and behold, after a few weeks of use is not only the spring just around the corner, but I regret quietly not to have grasped much earlier for this "upgrade".
The thermostat itself is relatively unspectacular in shape, look and feel. Not necessarily a beauty in completion, but practical and functional. Quite a lot of off-white plastic is accompanied by five gray buttons on the front, plus a very good display, which is backlit orange independently in operation. Two back used batteries provide the necessary power supply and are included. Pleasing - the Heizlux branding the product photos I am looking at all my purchased copies (three pieces) in vain.
The installation is rather uncomplicated. Simply unscrew the old manual thermostat and replace it with this new acquisition. At the largest online video platform in the world itself will find some helpful "To Do" video. For our part, built Kermi radiators direct mounting is possible for products from Heimeier, Junkers, Honeywell and Co. is a small additional plastic adapter for. Immediately after the initial installation to calibrate the thermostat based on an automated "adaptation phase" and is then ready in principle.
The precise coordination with one's own needs will in the following years some time, at least when you leave the preset temperature profile (comfort, economy, party, holiday, frost protection) and the thermostat with the individual heating periods for each day of the week and the desired time windows programmed. Here I find it literally the motto "no pain no gain" a, because at least in representative number one I was concerned about an hour to get me - supported by the detailed instructions - fully acquainted with the extensive possibilities. Alone therefore the immediate programming of all thermostats are recommended in series connection to the just learned to forget immediately.
But the effort is worth it, because the result is worthy of all honor. If desired, down to the smallest detail, the possibilities of modern programming can be exploited. Even seemingly unnecessary gimmicks, like an independent ventilation function, or a valve protection when unused for long periods are integrated.
For critical Zeitgeister: The servomotor of the thermostats is not completely silent and not to be missed, turning the valve. However, we are talking about at any time reasonable interference in seconds before the device if necessary sinking again in mechanical deep sleep for hours. In this respect, in my view, totally irrelevant and hardly worth mentioning secondary aspect.
Granted, I have no direct comparisons with other manufacturers' products. In this respect I can only this Heizungsthermostat certify a solid, reliable and absolutely satisfactory performance. So I am fully satisfied fact not only in terms of the price / performance ratio, but also save from now bares many cold days in energy resources and therefore (my) money. The good feeling is it to quasi free as an encore. So has technology.
