Troubleshooting

TE-6800 Series Temperature Sensors are
recommended for use only with Johnson Controls®
digital controllers. If the TE-6800 is not functioning
properly, use the following procedure to identify the
problem and determine a solution:
1. Check that the TE-6800 is mounted in a location
indicative of the space temperature (for example,
away from drafts or sunlight).
2. Check the wiring:
• Verify that the wiring is correct. The modular
jack connector must be inserted with the
proper polarity (not reversed). Misalignment
can cause damage.
DIP switch in the
default position.
Key:
Switch is in the up position (On).
Switch is in the down position (Off).
Note: Read the switch positions
from left to right.

• Check all supply voltage connections. See
Figure 2, Figure 3, or Figure 4, if necessary.
3. Check the settings:
• Verify that any scaling modifications, setpoint
adjustments, and overrides have been saved
and downloaded to the controller.
• Check the override status (Temporary
Occupancy mode vs. Unoccupied mode) at the
controller.
• Check the setpoint settings.
4. Confirm DIP switch positions if:
• the LED remains on or is dim
• the room sensor reading is outside of the
normal range for the space being sensed
Note: Make sure the DIP switch setting is correct for
the controller used with the TE-6800.
5. Replace the TE-6800 if the troubleshooting
suggestions fail to remedy the problem.
