﻿Potential-free switches, push-buttons or other contacts (e.g. magnetic contacts) can be connected to the inputs. In addition, it is possible to connect an NTC temperature sensor to input 3 for measuring a floor or room temperature.

*Switches, push-buttons or contacts*: The input acts independently of the relay outputs on the KNX. The functions "Switching", "Dimming", "Venetian blind", "Value transmitter", "Scene extension", "2-channel operation" and "Controller extension" can be set individually. In the "no function" setting, the input is deactivated.

*Temperature sensor (NTC)*: This setting is only available for input 3. If this setting is selected, input 3 can be used as an input for a temperature sensor. Parameters are then available in the application programme that define the acquisition of the measured value, the temperature adjustment and the transmission behaviour of the temperature value. The wired temperature sensor can be combined with an external temperature value. This makes it possible to form one measured value from up to two measured values.
