Table 21. T7350H Network Variable Summary. (Continued)

Nv Name L

ONSPEC™ Ref Name Class Description

nviManValue Manual Value In IN Manual override values for outputs:

Relays: Y1, Y2, Y3, Aux, G, W1, W2, W3

Analog Outputs: Mc, Mh

nviOccManCmd Occupancy Cmd In IN 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.

nviOccSchedule Occupancy Schedule In IN 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).
