occupancy Network command to force the VAV box into a specific manual occupancy
mode. This is an input from a network connected operator interface or
other node that indicates the state of a manual occupancy control thus
over riding the scheduled occupancy state. It is used along with other
occupancy inputs to calculate the effective occupancy of the node.
0: Occupied
1: Unoccupied
2: Bypass
3: Standby
255: null, ignore occupancy command.
Notes
Bypass: indicates that the space is occupied for BypassTime seconds
after nviManOcc is first set to OC_BYPASS. The timing is done by the
bypass timer in this node. If nviManOcc changes to another value the
manual occupancy state assumes the new value independent of the
bypass timer. If nviManOcc changes back to a null value and the bypass
timer is active, it will return to the Bypass mode.
Monitor digital input.
Typically used to override the local digital monitor input.
State
Off
On
Null
Note: The state value must be set to NULL to disable the override signal
unit less Monitor sensor. Typically used to override the local monitor analog sensor.

occupancy Allows an occupancy sensor at another node to be used as the occupancy
sensor for this node and is typically bound to the occupancy sensor output
from another node. The nviOccCmd must show UnOcc for the 300
seconds before OccSensorIn is changed to UnOcc. This makes it possible
for several occupancy sensors to be "ORed" together by binding them all
to OccSensorIn. If any one bound occupancy sensor shows Occ, then
OccSensorIn shows Occ for up to the 300 seconds after the last sensor
shows Occ.
0, 2, 3: Space is Occupied
1: Space is unoccupied
255: sensor not connected
Notes:
If a local occupancy sensor has been configured, the local sensor is
logically ORed with the network signal.
F Outdoor air temperature.
Used to enable peripheral heat minimum water flow below 40F outdoor air
temperature.
