Controllers with a connected motion sensor change to
Occupied
upon the detection of
primary airflow and motion in the space. The unit will remain in the
OCCUPIED
state as long
as periodic motion is detected and primary airflow continues. If motion stops, the controller
changes to
STANDBY
.
Unoccupied
The controller Occupancy mode changes to
UNOCCUPIED
when it detects a loss of
primary airflow. While in the
UNOCCUPIED
state, the controller will fully open the damper in
an attempt to reach the maximum airflow setpoint.
Loss of primary airflow is defined as less than 25% of the requested flow for at least 5
minutes. The Occupancy mode changes to
Occupied
or
Standby
once the actual airflow
is at least 30% of the requested flow.
Standby
In units with a connected motion sensor, the controller starts in
STANDBY
and changes to
OCCUPIED
after detecting motion in the space. Motion in the space is defined as two
movements detected within 5 minutes. The controller will change back to
STANDBY
after a
lack a lack of motion for the period specified by the variable Standby Time.
Standby mode is not valid for controllers without a motion sensor, unless commanded by a
building management system.
Space setpoints
There are four temperature setpoints each for heating and cooling for a total of eight
setpoints.

Types of setpoints
The SimplyVAV controllers may use any of the following setpoints based on a user entered
setpoint or the state of occupancy and standby which is described in the topic
