Very easy to assemble and einzulernen.Die range is groß.Man can conveniently enter their own code and then the system Enable or Deaktivieren.Und what I really really like from the Statusabfrage.So can by entering the code of the owner to know if the system Enabled or Disabled ist.Eigentlich I find the whole 2WAY very well they can be very many things such as the weekly schedule in which you can adjust when the system on the day itself Automatich Enable or Disable .And the up to 5 times! And many more !
