4.1 Presence detection using the built-in PIR sensor

By using a built-in presence detection sensor (also called PIR (Passive infrared

detector) sensor), the thermostat can detect the space occupancy and then do the

following:

● Activate the idle display. When no operations are performed, the thermostat

detects whether someone is in the room or not. If it detects someone is in the

room, it displays information such as room temperature, room air quality and

relative room humidity. If it detects no one is in the room, it turns off the screen.

● Change the operating mode from Unoccupied to Comfort. If an unoccupied room

is detected to be occupied when a scheduled Unoccupied mode is running, the

thermostat switches to Comfort automatically until the next scheduled mode starts.

However, you can decide not to switch to Comfort if you want. For more

information about operating modes, see the User guide.
