Occupancy detection
Why regulate based on occupancy?
Occupancy detection gives the opportunity to save energy at
the same time as a good indoor climate is guaranteed. Occu-
pancy detection can also be used to trigger the lighting control.
How is occupancy detected?
The occupancy signal can come from products with an integrated
sensor module (WISE SMB), presence sensor WISE OCS, external
presence sensor linked to WISE IRE or via the BMS system.
For occupancy signals from WISE SMB or WISE OCS, a delay
for switching o or on is congured in a conguration le or in
SuperWISE. When the external presence sensor is used with WISE
IRE, the delay for switching o or on is set in on the external
occupancy sensor.
Occupancy detection through the BMS system
Occupancy detection through the BMS system works as an
occupancy sensor in the room, but the occupancy sensor comes
from a register on room level. The occupancy signal from a BMS
system does not oversteer the room sensors, it adds a “virtual”
room sensor.
Accumulated occupancy
In order to measure how much time a room is used, the total
time that the room is in occupancy mode is calculated. Each
room has an individual counter. The total occupancy time in
hours is shown on a room level in tree view under Room infor-
mation. All counters can be reset simultaneously under settings
- Reset by clicking on “Reset occupancy hours, room”.
Operating case
When unoccupied a higher/lower temperature and lower air
ows can be permitted than for occupied. Some functions can
be deactivated in unoccupied mode, for example, cold draught
protection or air quality control.
