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
To set the Aux Mode:
1. Press the Menu icon.
2. Press Control Setup.
3. Press General.
4. Press Aux Mode and set accordingly.
5. Press to save and
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.
Commissioning Mode
The thermostat controller has a built-in commissioning mode, which is designed to allow you to quickly test
equipment wiring and functionality. Commissioning mode temporarily disables the control logic, and allows you to
manually command any individual output. Commissioning is designed to be the last step of the installation process
after configuring the controller for the equipment being controlled, and the available options in commissioning
mode are dependent on the controller configuration. To enter commissioning mode:
1. Press the Menu icon.
2. Select Commissioning.
3. Confirm that the selection was intentional. (The control is overridden upon selecting Confirm).
