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 that
opening the door does not stop an Occupied period started by the motion sensor prior to opening the door.
Table 11 provides the polarity of the inputs.
Aux control
The TEC has an auxiliary output that can be configured to operate in a few different ways. The Aux Mode supports
the following 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
To set the Aux Mode:
1. Press the Menu icon.
2. Press Setup.
3. Press General Control Setup.
4. Press Aux Mode and set accordingly.
5. Press
Save and the back arrow to return to the previous screen.
This option is also exposed to the BAS through the point AUX-MODE.
When the Reheat installed parameter is set to True, the Aux output is used for Reheat Output. The setting for the
Aux Mode is ignored when reheat is enabled.
