3.1 Presence detection using the built-in PIR sensor

A6V10733807_enUS_c
By using a built-in presence detection sensor (also called PIR (Passive infrared
detector) sensor), the thermostat detects occupancy and then does the following:
●
Activates idle display. When no operations are performed, the thermostat
detects presence in room. Upon presence, it displays information such as room
temperature, room air quality and relative room humidity. If unoccupied, it turns
off the screen.
●
Changes the operating mode from Unoccupied to Comfort. If presence is
detected in a formerly unoccupied room during a scheduled Unoccupied
period, the thermostat switches to Comfort automatically until the next
scheduled mode starts. However, this function is disabled by default and must
be enabled manually if so desired.
