Door/Window Contact
The indispensable all-rounder in the Bosch Smart Home System
Reliably detects open doors and windows
The Door/Window Contact detects open windows and doors and immediately alarms the Bosch Smart Home System in case of a break-in. It also reports open windows to networked radiator thermostats so that they do not continue to heat unnecessarily while you ventilate. In this way, the intelligent door/window sensor ensures greater security and energy efficiency in your home.

Supports burglary
prevention
The status display of your doors and windows lets you see at a glance whether they are still open. This means that there are no favourable opportunities for burglars.

Raises the alarm
for burglars
You leave your home and turn on your alarm system. If uninvited guests open doors or windows in your absence, the Door/Window Contact triggers the alarm system.

Prevents unnecessary
energy loss
If the door/window sensor detects an open window, the valves on the radiator close. If you close the window again, the radiator heats up again to the set temperature.
How it works
Door/Window Contact
The Door/Window Contact with the triple benefit: it reminds you of open windows or doors, alarms you in case of burglary and reports open windows to networked radiator thermostats so that they do not continue to heat senselessly while you are airing out.
