This product makes it easy to program with 2x6 programs: 6 for ignition, 6 for extinction. Each program is repeatable on 1 particular day or 5-day week, or 6 days or just the weekend. Personally, I could do what I wanted with 2x3 programs. It still leaves room.
For installation, you need some electricity notions, what I did not have enough :) but after I thought I understood that the bottom connectors of the module operates as a switch, so you must a phase to get down, and it also shows a phase that is supplied when the timer is triggered. The portion of the high module is its power supply which is therefore with a phase and a neutral.
I do not understand the opinion of another buyer who said that this module pilot relays, for me it controls an outlet, therefore, its correct use.
Very good product, the manual is in several languages, including French.
The only small snag, the 6 buttons are named in German, but hey, you quickly understand.
The display (day notament) are in English and the time in 24-hour format.
