This flush-mounted socket from Merten is intended to dim all kinds of lamps. It is a universal dimmer, which means it can dim reactive, inductive and resistive loads. A pattress box is needed for installation. The unit is designed for use within a 2-wire system, which means that no neutral wire (blue) is needed for operations. This flush-mounted socket is no Z-Wave device but needs to be completed with an active Z-Wave-equipped switching-paddle like MER_50364419 or MER_504619 plus an appropriate mounting frame of the switch series selected. The socket provides the power to the active Z-Wave-equipped switching-paddle. The paddle itself controls the socket via electrical signals as well.
