Essentially mature product

As all my popular products for the FS20 series of ELV can be adjusted fully to the devices to be controlled and the radio timer. Thus, with the timer up to 4 different devices / device groups drive, where receivers can be not only individual addresses (individual devices / actuators) but also different, according to "programmed" groups of actuators (eg all devices in a room or all lamps in the house).
The included user manual is made carefully (which one is now not necessarily used) and also allows non-specialists the setting, taking some technology-affinity facilitates understanding safely. (The many possibilities to explain just not quite as simple as a ready-to-transmitter radio socket combination, how it is used).

I use the timer along with a radio-controlled socket from the same program (with automatic power off function!) And a wall switch as an additional transmitter to control the hot water circulation pump of the house with minimal energy consumption with no or minimal loss of comfort. (Switching on the pump via the timer to the known (integrated shower) times + possibility of manual start of the pump out of the bathroom (switch on the timer) and the kitchen (wall transmitter); automatic stop of the pump by means of the wireless socket (actuator .) integrated turn-off timer after about 2 minutes, so if the hot water reaches the far end of the cycle) First experience: Works fine.
The specially offered by ELV for controlling circulation pump module I have saved me, because I see no need to control the pump running time in addition on the heat of the water in the pipes.

Specifically, the timer-reviewed here, however, also has two disadvantages, which lead to deduction of points:

- The timer "forgets" all entries during battery change. Since the "programming" can take depending on the application several minutes, which is a bit lässtig. Other ELV products are better off. In turn, the price of the timer is low but ... you should perhaps choose a better device from the FS20 series.

- There are only 6 switching pairs (on / off) are available, of which I only need the on-Actions. (The receiving socket accepts yes switching off.) In the product description, it sounds as if could be every 12 switching actions of starts, but this is not the case.

All in all still a recommended product line for home automation.
