The temperature input records temperatures using a temperature sensor (265643) and sends them to the convenient electrical installation. The simple control of, for example, a conservatory can also be carried out. The device is installed in the switch, junction or installation box. The device is powered by a button battery (CR2477N) and can therefore be easily attached anywhere (screwed and glued). Attention: For exact measurement and display of the values, record the deviation using a reference measuring device and set the 'offset' in the MRF. Battery included in delivery. Delivery without temperature sensor
