Works well, but the description and use the reserve to enlightened hackers The brief instruction is only used to approach the commands, you should grope with English menus to get to what you want. (In the HEAT menu to the maximum temperature and the minimum temperature for COOL) Also be aware that it is not possible to set a start and end each cycle but only to program 4 cycles after (morning, day, evening, night) with possibilities of different temperatures; at least that's what I managed to do. In short, a purchase I do not regret even if settings have occupied me a few hours to draw a satisfactory use.
