nviOccManCmd (nviFP03)
This input network variable is used to command the Controller into different occupancy modes.
It is typically sent by a wall-mounted occupant interface module or supervisory node, to manually con-
trol occupancy modes, or override the scheduled occupancy.
If a local Bypass Input is present, it can be used in conjunction with this network variable input.
The local input, when active, forces a Bypass request (equivalent to OC_BYPASS), overriding nviOcc-
ManCmd for the duration of the Local Bypass Time (determined by the configuration property nciBy-
passTime).
When nviOccManCmd indicates OC_BYPASS, the Local Bypass Time is also used.
Whenever an update of nviOccManCmd is received indicating OC_BYPASS, the bypass timer is
restarted.
This input is used in conjunction with nviSchedule1 and nviOccSensor (if installed) to determine the ef-
fective occupancy mode.
Refer to nvoEffectOccup(nvoFP02) for more information.

Default Value
nviFP03
SNVT_Occupancy
0 = OC_OCCUPIED: The Space Comfort Controller should
operate in the occupied mode
1 = OC_UNOCCUPIED: The Space Comfort Controller should
operate in the unoccupied mode
2 = OC_BYPASS: The Space Comfort Controller should
operate in the occupied mode for a period of time defined by
nciBypassTime.
3 = OC_STANDBY: The Space Comfort Controller should
operate in the standby mode
0xFF = OC_NUL: This is the initial value after power-up and it
remains until another value is received. It is used to indicate
that this network variable input is invalid, unused or to cancel a
previous command.
0xFF = OC_NUL
nviOccSensor (nviFP04)
This input network variable is used to indicate the presence of occupants in the controlled space and it
is typically sent by an occupancy sensor.
In cases where an occupancy sensor is hardwired to the Space Comfort Controller, a valid value for
nviOccSensor will take precedence over the hardwired input.
This input is used in conjunction with nviSchedule1 and nviOccManCmd (if installed) to determine the
effective occupancy mode.
Refer to nvoEffectOccup(nvoFP02) for more information.

Default Value

SNVT_occupancy
0 = OC_OCCUPIED: The occupancy sensor is indicating that
there ARE occupants in the space.
1 = OC_UNOCCUPIED: The occupancy sensor is indicating
that there are NO occupants in the space.
0xFF = OC_NUL: This is the initial value after power-up and it
remains until another value is received. It is used to indicate
that this network variable input is invalid or unused. OC_NUL
is equivalent to OC_OCCUPIED.
All other enumerations are handled as equivalent to OC_NUL.
