FRITZ!DECT 350 is a compact door/window contact that immediately recognises when doors and windows are opened, closed or tilted. The DECT ULE sensor is the ideal addition to the FRITZ!DECT 301 and 302 smart radiator controllers, which work together to ensure efficient heating energy savings. All FRITZ! smart home and compatible Zigbee devices can be controlled with the FRITZ!DECT 350... and enable many scenarios and routines to be set up. The status of the sensor, e.g. open or closed windows, is displayed in the FRITZ!App Smart Home, on the FRITZ!Fon and in the FRITZ!OS for control and greater security. The compact FRITZ!DECT 350 can be installed concealed in many window frames with a Euro rebate.
