Hi Guys,
This is the way to use a SIAX12 in a "Hotel switch" (Hotelschakeling,wisselschakeling). With one adjustment to the drawing, That you need to use the <b>Grey</b> wire instead of the <b>Red</b> one. The Grey one is for the internal relay of the SAIX12. You don't have to change any wires just install the SAIX12.
