Faults
Remote Zone Temp Fail
Supply Temp Fail
Outdoor Temp Fail
Internal Sensor Fail
OA Lockouts Disabled
Econ Unavailable
Dehum Unavailable
Service
Dirty Filter
Calibration Corrupt
Zone Temp Unreliable
TEC3000 Series Networked and Wireless Single- or Two-stage Economizer Thermostat Controllers Quick Start
Probable causes
The External Zone Temperature
sensor has been disconnected or has
failed.
The External Supply Temperature
sensor has been disconnected or has
failed.
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.
Dehumidification is unavailable
because the zone humidity sensor has
failed or the humidity reading is not
reliable.
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.
Guide
Solutions
1. Check the wiring of the sensor.
2. If intentionally disconnected, reset sensors
through the menu.
3. If the problem persists, order replacement
units and return the affected devices to
Johnson Controls under the RMA program.
1. Check the wiring of the sensor.
2. If intentionally disconnected, result fault by
entering the menu, enter Control Setup, and
select Inputs to reset the sensors.
3. If the problem persists, order replacement
units and return the affected devices to
Johnson Controls under the RMA program.
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 is 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.
Order replacement units and return the affected
devices to Johnson Controls under the RMA
program.
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.
Order replacement units and return the affected
devices to Johnson Controls under the RMA
program.
