Good but .... German programming uniquement.et careful documentation

Well, although the documentation is in German it's OK anyway with the help of online translator!
I used it to replace the faulty thermostat a wine cellar.
Programming the temperature startup and shutdown is simple.
Note: it is also possible to use for example in heating mode, the heating system supply at 17 ° and stop at 19 ° or as in my cooling mode if (starting at 15 ° and stop at 13 °).
Warning: after a few weeks of use I've realized that programming was "lost" after power failure following a storm.
