Manual override values for outputs:
Relays: Y1, Y2, Y3, Aux, G, W1, W2, W3
Analog Outputs: Mc, Mh
Manual occupancy is a method to command the occupancy state
from a network workstation. Effective occupancy override works
on a "last in wins" basis. That is, the last occupancy override
command received from any source determines the override state.
The workstation can command occupied, unoccupied, standby,
bypass, or not active (null).
nviOccManCmd is used to place the T7350H into manual
occupancy (note there is no timer associated with
nviOccManCmd).
Manual occupancy input from a network device:
0: OC_OCCUPIED
1: OC_UNOCCUPIED
2: OC_BYPASS
3: OC_STANDBY
-1: OC_NUL not connected (mains power up).
Others: same as OC_NUL.
NOTE: If nviOccManCmd is OC_BYPASS and the bypass timer
(nvoData1.bypassTime) times out, then nviOccManCmd
is set to OC_NUL.
There are 2 distinct modes of operation: local schedule and
network schedule. The local schedule mode causes the T7350H
to change set points by using the scheduler in the T7350H. The
network schedule mode causes the T7350H to change set points
from a network-based scheduler. The network schedule, when
valid, overrides the local schedule.
The network schedule input is nviOccSchedule. This input has
current state, next state and tuncos (Time Until Next Change of
State). It is bound from another scheduler such as the XL15A or
T7300/Q7300H. The XL15B or a workstation can also write to it in
an "unbound" relationship.
If the network schedule is not periodically updated the T7350H
resumes local scheduling. Periodically means at a rate greater
than the fail detect time. This rate is typically 55 seconds, 300
seconds maximum. (The actual rate and maximum depend on the
configured heartbeat and failure detect times.)
Current scheduled occupancy state:
0: OC_OCCUPIED
1: OC_UNOCCUPIED
3: OC_STANDBY
Others: same as OC_NUL.
-1: OC_NUL (mains power up and fail detect value).
Next scheduled occupancy state:
0: OC_OCCUPIED
1: OC_UNOCCUPIED
3: OC_STANDBY
Others: same as OC_NUL.
-1: OC_NUL (mains power up and fail detect value).
Time in minutes until next scheduled change of occupancy state:
0: (mains power up and fail detect value).
