﻿The controller detects the room temperatures using one or possibly two external KNX temperature sensors (e.g. push-button sensors with temperature measurement). Depending on the configuration, the 2-byte objects "Room temperature - Measured value 1" and, optionally, the additional "Room temperature - Measured value 2", are enabled. After a device reset, the controller will first wait for valid temperature telegrams to both objects until control starts and a command value, if applicable, is output.

*Temperature input 1*: The actual temperature is determined solely via an external temperature value. In this case, the KNX temperature sensor is connected to the controller via the 2-byte object "Room temperature - Measured value 1".

*Temperature input 1 and 2*: The actual temperature is determined using two external temperature values. The selected temperature sources are combined. In this case, the KNX temperature sensors are connected to the controller via the two 2-byte objects "Room temperature - Measured value 1" and "Room temperature - Measured value 2".
