Selecting schedule source
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.
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.

Scheduling (for all models)
About this task:
The occupancy schedule comes from either the weekly
scheduler built into the TEC or as an input from the
BAS. The Schedule Source must be selected to tell the
controller where to read the occupancy source from. To
select the schedule source, complete the following steps:
1. Press the Menu icon.
2. Press Scheduling.
3. Press Schedule Options.
4. Press Schedule Source and select Schedule (Local)
or External (BAS).
5. Press Save and the back arrow to return to the
previous screen.
This option is also exposed to the BAS through the point
OCC-CONFIG. If BAS is configured as the occupancy
source, map the point NET-OCC in and write to that
point to control the schedule remotely. If the supervisor
goes offline (as identified by the network icon going
away on the home screen of the TEC), the control logic
automatically falls back to the local schedule as the
occupancy source. If that schedule is not set, the default
occupancy is continuously occupied.
Setting the local schedule
About this task:
A weekly occupancy schedule with up to four occupancy
events for each day can be set locally on the TEC and
operate independently of a supervisor. To set the
schedule, complete the following steps:
1. See Selecting schedule source to ensure the
schedule source is set to Local.
2. Press the Menu icon.
3. Press Scheduling.
4. Press Set Schedule.
5. Select the days to which the schedule should apply.
If events are already set for the selected days,
they appear in the corresponding event box. If any
events conflict between selected days, an asterisk
appears in the event box. See Figure 16.
6. Select the Occupancy Status icon for the event. See
Figure 17.
Important: Internally, the TEC3000 uses a
BACnet schedule where daily schedules are
independent of the previous and next days.
The default occupancy of the TEC3000 from
the factory is set to Occupied. As a result, a
daily event at 12:00 AM must be scheduled if
you do not want the controller to transition to
Occupied Mode at midnight.

7. Select the Time Set button. See Figure 18.
