﻿At this point it is determined how inputs 1 and 2 operate in the event of an internal effect on the relay output. Setting this parameter adjusts the inputs to the connected switches or buttons.

*Single-area operation (I1 -> SO1)*: Input 1 (I1) then acts directly on the switching output (SO1) without KNX communication. In this application, switches or bell pushes can be connected, for example. Input 2 optionally acts on the KNX in this configuration.

*Two-area operation (I1 & I2 -> SO1)*: Inputs 1 (I1) and 2 (I2) act together directly on switching output (SO1) without KNX communication. In this application, for example, a 2-fold rocker switch can be connected.
