TEC3000 Series Single- or Two-Stage Economizer Thermostat Controllers Installation Instructions

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 7 for scheduling information.
Once the Occupancy Schedule command is set, the effective occupancy is determined by settings shown in the
Occupancy Determination table. See Table 6.
The occupancy schedule can come 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:
1.
Press the
Menu
icon.
2.
Press

Press
to save and
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
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:
1.
See
Selecting Schedule Source
to ensure the schedule source is set to Local.
2.
Press the
Menu
icon.
3.
Press
