Digital controller can be disturbs by a power outage

The manual is present, which was good because the operation is not obvious.
However, once the read instruction, programming becomes simple.
Max 14 beaches to program, and it may be performed for each day.
1 beach is to ignition and extinction by defining the time this action happens.
After we put self phase and the programmer is ongoing.

Its main defect that makes him lose a lot of its appeal is its behavior during a power cut.

Indeed, if the switching on or off takes place during downtime of electricity => it is not.
Power failure at another time => considered (no problem), the programmer is not disturbed through its integrated battery.

Depending on the time of the power cut, we can end up with a device that should have been switched on or off but does not.
Too bad, for a device with an integrated rechargeable battery, its design makes a little ineffective during a power cut.

Hence my rating to 3 stars for a practical device, but less reliable than a manual timer during a power cut.
