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 Occupancy
sequence on page 52.
Active setpoint—The active setpoint is the current setpoint. The active setpoint is
determined by the following.
l If the space is occupied, the controller uses the occupied setpoint as the active
setpoint.
l If a STE-6014 and STE-6017 is connected, the Active setpoint is set by the dial to be a
few degrees above or below the Occupied setpoint. The range of adjustment is set by
the variable STBY OFFSET. The dial setting does not change the setpoint when in the
Unoccupied or Standby state.
l If the space is unoccupied the controller uses the unoccupied setpoint as the active
setpoint.
l If controller is in standby, the controller calculates the standby setpoint.
l 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.
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 setpoint used when the system is
unoccupied .
Standby setpoint—The standby setpoint is used when the controller is in the standby state.
It is a value calculated from the occupied setpoint and the variable STBY OFFSET. The
standby offset value is entered by the controls technician during controller setup and system
commissioning. See the topic Occupancy sequence on page 52.
Setpoint limits
The programming in the SimplyVAV controller limits the setpoint entry so that no heating
setpoint is set higher than its corresponding cooling setpoint.
If a user is adjusting a setpoint and it falls within the range set by the value of Minimum
Setpoint Differential, the corresponding setpoint will be changed to maintain the differential.
For example, the Minimum Setpoint Differential is 4°F and the Occupied Heating setpoint is
