TEC3000 Series Wireless Single- or Two-Stage Economizer Thermostat Controllers Installation Instructions
Probable Causes
The External Outdoor Air Temperature
sensor has been disconnected or has
failed.
An internal sensor has failed on the
TEC.
The Local Outdoor Air Temperature
sensor has become disconnected or
failed or a network Outdoor Air
Temperature sensor has timed out, and
the TEC is no longer shutting down
equipment based on the OA lockout
setpoints.
The Outdoor Air Temperature sensor is
not installed, has failed, or has been
disconnected and the TEC can no
longer control the economizer.
Equipment connected to the BI
configured for a Service alarm is
triggering the alarm.
Equipment connected to the BI
configured for a Dirty Filter alarm is
triggering the alarm.
Factory calibration data is lost or is not
installed.
All sources of zone temperature are
unreliable, including the onboard
sensor.
The switch connected to the BI
configured for Open Window is sensing
that the window is opened, and control
has shut down.
The switch connected to the BI
configured for Fan Lock did not sense
airflow within 10 seconds of starting the
fan, and control has been shut down.
Solutions
1. Check the wiring of sensor.
2. If intentionally disconnected, reset sensors
through the menu.
3. If problems persist, order replacement units
and return the affected devices to Johnson
Controls under the RMA program.
Order replacement units and return the affected
devices to Johnson Controls under the RMA
program.
1. If the source of outdoor air temperature was a
locally connected sensor, follow the steps for
the Outdoor Temp Fail alarm.
2. If the source of outdoor air temperature was a
BAS, check the BAS to ensure that it is still
online and providing the TEC with the
temperature reading. If removal of the BAS
mapping was intentional, reset sensors
through the menu.
Follow the same steps as Outdoor Temp Fail
alarm.
Service the equipment by way of the
manufacturer's recommendation.
Replace the filter in the equipment as explained
in the manufacturer's instructions.

Order replacement units and return the affected
devices to Johnson Controls under the RMA
program.

2. Check sensor functionality with an ohmmeter,
and verify the wiring to the TEC.
3. If problems persist, order replacement units
and return the affected devices to Johnson
Controls under the RMA program.
1. Inspect equipment to ensure fan functions.
2. Check sensor functionality with an ohmmeter,
and verify wiring to the TEC.
