Setpoints and related data

The setpoints and related data include the following items:

  • Occupancy mode (OccMode)
  • Network temporary occupancy request (NetTempOcc)
  • Network occupancy request (NetOcc)
  • Temporary occupancy timeout (TempOccTimeout)

Inputs

The inputs include the following items:

  • Occupancy input (OCC)
  • Schedule occupancy (accessible through MAP or NAE only)
  • Net sensor request (no EM values)

Outputs

The outputs include the following items:

  • Occupancy input source (OccSrc)
  • Operational occupancy (OprOcc)

Operation

Note: This section presumes the UCB is not part of a Verasys or CCS system.

When the occupancy mode is set to external the operational occupancy is determined by one of the following: occupancy input, network occupancy request, or a net sensor occupancy request. If any one input is occupied, then the operational occupancy is occupied. If all inputs are unoccupied, then the operational occupancy is unoccupied.

When the occupancy mode is set to schedule, the operational occupancy is determined by the interaction of schedule occupancy and net sensor occupancy request. The following points apply:

  • If temporary occupancy input is false, then the operational occupancy is based strictly off the schedule occupancy. The schedule occupancy is changeable through the MAP Gateway. The default schedule is occupied M-F 8:00a.m.-5:00p.m.
  • If temporary occupancy input is true and scheduled occupancy is unoccupied and network temporary occupancy request is true, then operational occupancy is bypass (occupied) for the duration of the temporary occupancy timeout.
  • If temporary occupancy input is true and scheduled occupancy is occupied, then operational occupancy is occupied.
