Configuring Occupancy - Johnson Controls TEC3000 Series Installation Manual

Configuring occupancy

To adapt to nearly any application, the TEC3000 controller
supports a wide variety of occupancy sources, such as:
• Local stand-alone weekly scheduler
• Remote schedule from BAS
• Occupancy sensor (internal or remote)
• Occupancy binary input (configurable)
• Manual occupancy override
• Temporary occupancy (by interacting with the screen
while in unoccupied mode)

Not Configured
1 Not Configured means that neither BI1 Config nor BI2 Config is set to Occupancy BI. Open and Closed refer to the current state of
the BI when configured as Occupancy.
2 True is triggered by interacting with the screen during a scheduled unoccupied period. A value of True can only occur when the
schedule is not Occupied.
3 When triggered by a BI configured for Temp Occ, the input is ignored when the schedule is Occupied, the Manual Occupancy Mode
is notNo Override, or an Occupancy BI is configured.
4 Built-in occupancy sensing (PIR) or BI configured for Motion NO or Motion NC.
5 Not Set occurs when no events are scheduled through the local scheduler, or the schedule source is set to Schedule and the
Schedule is writing Not Set as the schedule.

Scheduling (for networked models)
The TEC3000 Thermostat Controller can operate as a
stand-alone unit with an internal schedule or scheduled
with an external schedule. The OCC-CONFIG object sets
the method used for scheduling.
If the OCC-CONFIG is set to External, the NET-OCC object
is used to control the unit externally.
If the OCC-CONFIG is set to Schedule, the internal
schedule commands the LOCAL-OCC object, which sets
the Occupancy Schedule command.

TEC3000 Series Proportional Fan Coil Thermostats Installation Guide
• Temporary occupancy binary input
Occupancy is determined using a top-down decision
matrix as shown in Table 9.

Note: If you do not have a schedule in the
Schedule object and you have the OCC-CONFIG
set to Schedule, you can control the unit with the
LOCAL-OCC object externally; however, we do
not recommend this method. See Table 10 for
scheduling information.
Once the Occupancy Schedule command is set, the
settings shown in the occupancy determination table
determine the effective occupancy. See Table 9.
