﻿The mode of operation of the inputs depends on the function of the outputs (blind output or switching output). hen using the relays as switching outputs, the mode of operation of the inputs (single-surface operation or dual-surface operation) can be parameterised. At this point it is determined how inputs 1 and 2 operate in the event of an internal effect on the relay outputs. Setting this parameter adjusts the inputs to the connected switches or buttons.

*Two-area operation (I1 & I2 -> VBO)*: In this application, inputs 1 and 2 act internally on the blind output without KNX communication. The mode of operation of the inputs is then predefined and cannot be changed. In this application, for example, a blind switch or push-button can be connected. Simultaneous operation of both inputs must be avoided. This setting corresponds to the delivery status of the device.
This setting is only available when using the relays as blinds output.

*Single-area operation (I1 -> SO1, I2 -> SO2)*: Input 1 (I1) acts directly on switching output 1 (SO1), input 2 (I2) acts directly on switching output 2 (SO2), in each case without KNX communication. In this application, switches or bell pushes can be connected, for example.

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

*Two-area operation (I1 & I2 -> SO2)*: Inputs 1 (I1) and 2 (I2) act together directly on switching output 2 (SO2) without KNX communication. In this application, for example, a 2-fold rocker switch can be connected. With this configuration, the first switching output can only be controlled via the KNX.
