Default Null Value: OC_NUL = 0xFF Releases the thermostat to its internal
Occupancy function: Internal scheduling, PIR, etc….
Valid Range:
0 = OC_OCCUPIED
1 = OC_UNOCCUPIED
2 = OC_BYPASS – Not Used
3 = OC_STANDY – Not Used
network input
SNVT_occupancy
nviOccCmd
0xFF = OC_NUL (Release to PIR or internal schedule)
This output network variable is used to indicate the actual occupancy mode of the
unit. This information is typically reported to a supervisory controller or provided
to another Space Comfort Controller to coordinate the operation of multiple units
Valid Range:
0 = OC_OCCUPIED
1 = OC_UNOCCUPIED
2 = OC_BYPASS

nvoEffectOccup
3 = OC_STANDBY – Not Used
Note 1: OC_BYPASS can be initiated by local override. NvoEffectOccup will only be
in OC_BYPASS for the duration of the ToccTime (nciGenOpts), until reinitiated by
either a transition of the local input or an update to nviOccManCmd.
