TEC3000 Series Single- or Two-Stage Economizer Thermostat Controllers Installation Instructions
26
Setting both BIs to the same function is supported for all except Occupancy, Fan Lock, Open Door, and Open
Window. If both BIs are set the same for those four, BI2 is ignored and only BI1 is used.
The Open Door option works 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:
Opening the door does not stop an Occupied period started by the motion sensor prior to opening the door.
The polarity of the inputs are provided in Table 9.
Note:
Supply Fan Status and Fan Lock are not compatible with each other. The TEC3000 only controls one fan so
it cannot accept feedback from two fan sources. When configuring BI-1 and BI-2, choose either Supply Fan Status
or Fan Lock, but not both.
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
•
Off—Output is turned off (relay open), used by a BAS to directly control the AUX output
