Everyone already has a smart phone and therefore we have adapted the time control, of the digital switching clock SHT-7 in the relay-repertoire of ELKO EP. It controls switching depending on the manual setting of daily or weekly programs. In total, you can set up to 100 different switching programs for one device. The installation and commissioning of equipment works very simply, using a smartphone. With Near Field Communication, which allows two devices to communicate wirelessly within a few centimetres (this is typically used for credit cards and payment terminals), you can also transfer individual settings to other devices, clone them, and back them up. You will appreciate this and use it extensively when you are installing individual and multiple devices. The transfer of programs and programming can save a lot of time and work.
