•
Service—Input from the equipment to display a service warning on the thermostat
•
Dirty Filter—Input from the equipment to display a dirty filter fault on the thermostat
•
Motion NC—External motion sensor with a closed contact output when no motion is detected
•
Motion NO—External motion sensor with an open contact output when no motion is detected
•
Temp Occ—Trigger to place controller into Temporary Occupancy mode
•
Occupancy—Direct override of Occupied and Unoccupied
•
Supply Fan Status—Input from the equipment to display a Supply Fan Fault. When Fan Alarm Action is set to
Shutdown and the Supply Fan Fault is active, the TEC3000 disables the fan, heating, and cooling. When the
Fan Alarm Action is set to Enable and the Supply Fan Fault is active, the TEC3000 allows the fan, heating, and
cooling to operate during the Supply Fan Fault.
Setting both BIs to the same function is supported for all options except Occupancy, Fan Lock, Open Door, and
Open Window. If both BIs are set the same for those four options, BI2 is ignored and only BI1 is used.
The Open Door option is designed to work in conjunction with a motion sensor, either built into the TEC or
connected to another BI configured for Motion NO/NC mode. When the door is open, motion detected by the
sensor is ignored. Note that opening the door does not stop an Occupied period that was started by the motion
sensor prior to opening the door.
The polarity of the inputs are provided in Table 9.

Configurations that support both BIs to be configured for the same feature of the action that occurs when either of the BIs
enter that state.
Aux Control
The TEC has an auxiliary output that can be configured to operate in a few different ways. The Aux Mode supports
seven different options:
•
Not Used—Output is always off
•
Occupied NO—Output is normally open, but closes when occupied
•
Occupied NC—Output is normally closed, but opens when occupied
•
Occupied Fan NO—Output is normally open, but is closed when occupied with the fan running
•
Occupied Fan NC—Output is normally closed, but is open when occupied with the fan running
•
On—Output is turned on (relay closed), used by a BAS to directly control the AUX output
