the product and a good value, price for a touchscreen. by programming against is frankly not easy (only in English not very clear), and especially the correctable factory settings are numerous and sometimes confusing, strange view: indeed it is a thermometer that you can adjust the value of the temperature display. the displayed value can be adjusted +/- 5 ° !! Lhystérésis is too large and adjustable from 0.5 to 4 °. (Eg, a setting of 0.5 degrees, and a threshold of 20.5 °, the product is activated and stops at 20.4 to 21). no possibility of different programs for 7 days (Mode 5 + 2; 6 + 1, or 7) For the price that's enough for my bathroom.
