.

Active setpoint

—The active setpoint is the current setpoint. The active

setpoint is determined by the following.

If the space is occupied, the controller uses the occupied setpoint as the
active setpoint.

If the space is unoccupied the controller uses the unoccupied setpoint as
the active setpoint.

If controller occupancy is

Standby

, the controller calculates the standby

setpoint.

A user with Password 1 can enter an active setpoint from a SimplyVAV
digital wall sensor. This entry will change the occupied setpoint within
the setpoint limits.

If a sensor with a dial setpoint is connect to the controller, the dial
position is used for the active setpoint only when the Occupancy stae is

Occupied

.

Occupied setpoint

—A temperature setpoint entered by the controls

technician during controller setup and system commissioning. This is the
setpoint used when the controller is occupied which is determined by
primary airflow and, on controllers equipped with motion sensors, motion in
the zone.

Unoccupied setpoint

—A temperature setpoint entered by the controls

technician during controller setup and system commissioning. This is the
