value will be used in the T7350H as the primary controlled 

variable. The local space temperature sensor of the 

T7350H is ignored until the network sensor fails.

• Space Humidity Sharing: 

If a valid humidity value is received at the T7350H Space 

Humidity network variable input, that value will be used in 

the T7350H as the humidity control variable. The local 

space humidity sensor of the T7350H is ignored until the 

network sensor fails. 

• Current Setpoint Sharing: 

If a valid setpoint value is received at T7350H nviSetpoint, 

that value will be used by the T7350H as the center 

setpoint. The heat and cool setpoints are then calculated 

from this value and are used in the T7350H as the 

occupied setpoints. During unoccupied periods, 

nviSetpoint is ignored. 

• Occupancy Sensor Sharing: 

If a valid value is received at the T7350H occupancy 

sensor network variable input, that value will be used in the 

T7350H as the occupancy sensor. The local T7350H 

occupancy sensor is ignored until the network sensor fails. 

NOTE: The occupancy or motion sensor is active whenever 

the device is scheduled “Occupied” and a remote or

 

network occupancy sensor is configured.

The T7350H effective occupancy is determined in Table 6.

• Occupancy Bypass: 

Any internal or external scheduled unoccupied state in the 

T7350H is overridden by a network occupancy bypass 

command. Bypass is a method to command unoccupied 

override over the network from another controller (typically 

a T7350H or XL10). The source controller manages the 

bypass timing. 

• Manual occupancy: 

Provides 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). 

There are several ways to return the device to normal 

schedule operation. 

1. Power failure reset at the T7350H.

2. Workstation issues a “not active” (null) network com-

mand to T7350H.nviOccManCmd.

3. User activates “Temporary Occupied” button on the 

local keyboard. This can be followed by a “Run Sched-

ule” local command.

4. If manual occupancy is commanded to bypass and the 

bypass timer times out.
