Configuration setting
Description
Controller state when presence detected
One of the following controller states is configured as active when presence is
detected:
✓
Occupied
✓
Bypass
(default setting)
Presence activation delay (min)
The controller checks for presence continuously when the controller is in the state
specified by the
Preset controller state
setting. When presence is detected, a timer
starts and the controller waits this delay time (in minutes) before changing to the state
specified by the
Controller state when presence detected
setting.
If presence is not detected continuously during this delay time, for example, if a person
leaves the room before the delay time has passed, the controller does not change to
the presence detected controller state, and the timer is stopped and reset.
Presence deactivation delay (min)
The controller checks for presence continuously when the controller is in the presence
detected controller state. When no presence is detected anymore, a timer starts and
the controller waits this delay time (in minutes) before changing to the state specified
by the
Preset controller state
setting.
If presence is detected again during this delay time, for example, if a person re-enters
the room before the delay time has passed, the controller stays in the presence
detected controller state, and the timer is stopped and reset.
Activate presence if high CO2 level
Off:
Presence detection via the CO
2
sensor is disabled (default setting).
On:
Presence is detected via the CO
2
sensor by using the
CO2 level for presence acti-
vation (ppm)
setting.
CO2 level for presence activation (ppm)
Presence is detected via the CO
2
sensor when the measured CO
2
level exceeds this
value.
Hysteresis for presence deactivation (ppm)
Specifies the hysteresis for when presence is not detected via the CO
2
sensor
anymore. For example, if presence has been detected at 800 ppm and this setting is
160 ppm, the controller stops detecting presence at 800-160 = 640 ppm.
