This device obeys the finger and the eye in the program had ordered him to follow. The display is clear. Convenient buttons to use. Programming is done on demand, half a degree by half a degree, day by day, hour multiple choice. The instructions supplied allows a non handyman install it without difficulty. The only critical point is the annual battery replacement, you need to perform a time-limited to 20 seconds, otherwise the program data is lost, and there would have to reprogram the device as the first day with the help of the manual. We should get to do this replacement quickly, but the opening of the plastic cover is hard and we are afraid of breaking it by force. Apart from this detail, this is probably the best room thermostat in its class.
