Finally, a great application for the NFC interface: Finger gestures instead of mechanical buttons, switches, or dials program the timer 12.51. Here, FINDER uses the smartphone to communicate with the device. Smartphone apps are particularly appealing because they are clear and intuitive to use. The device for DIN rail can be fully configured with the FINDER Toolbox app on the smartphone. Once the configuration is complete, the data set is transferred to the timer simply by placing the smartphone on the device housing. The data transfer works even without power supply to the timer, as the smartphone itself induces the NFC chip to receive. Consequently, it can be comfortably configured in the office after unpacking and then installed in the distribution board or control cabinet already pre-programmed.

The LC display with backlighting for setup, programming, and status is easy to read from almost any angle. An internal battery (replaceable) allows for power-free setup, programming, and status with a 6-year reserve and is used to maintain the program in case of a power failure. The simple programming of daily and weekly schedules is, of course, also possible with the joystick. The summer/winter time change is preset. The shortest switching time is 30 minutes. There is a secure separation between the power supply and contacts, and the contact material is cadmium-free.
