TEC3000 Series Single- or Two-Stage Economizer Thermostat Controllers Installation Instructions
37
OA Lockouts Disabled
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.
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.
Econ Unavailable
The Outdoor Air Temperature sensor is
not installed, has failed, or has been
disconnected and the TEC can no
longer control the economizer.
Follow the same steps as Outdoor Temp Fail
alarm.
Dehum Unavailable
Dehumidification is unavailable
because the zone humidity sensor has
failed or the humidity reading is not
reliable.
1. If the source of zone humidity was a BAS,
check the BAS to ensure that it is still online,
and providing the TEC with the humidity
reading. If removal of the BAS mapping was
intentional, reset the sensors through the
menu.
2. If the problem persists, order replacement
units and return the affected devices to
Johnson Controls under the RMA program.
Service
Equipment connected to the BI
configured for a Service alarm is
triggering the alarm.
Service the equipment b y way of the
manufacturer's recommendation.
Dirty Filter
Equipment connected to the BI
configured for a Dirty Filter alarm is
triggering the alarm.
Replace the filter in the equipment as explained in
the manufacturer's instructions.
Calibration Corrupt
Factory calibration data is lost or is not
installed.
Order replacement units and return the affected
devices to Johnson Controls under the RMA
program.
Zone Temp Unreliable
All sources of zone temperature are
unreliable, including the onboard
sensor.
Order replacement units and return the affected
devices to Johnson Controls under the RMA
program.
Open Window
The switch connected to the BI
configured for Open Window is sensing
that the window is opened, and control
has shut down.
1. Close the window to resume control.
2. Check sensor functionality with an ohmmeter,
and verify the wiring to the TEC.
3. Order replacement units and return the
affected devices to Johnson Controls under
the RMA program.
Fan Lock
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.
1. Inspect equipment to ensure fan functions.
2. Check sensor functionality with an ohmmeter,
and verify wiring to the TEC.
3. Reset fault by entering the menu, selecting
Fault Status, and selecting the Fan Lock.
4. If problems persist, order replacement units
and return the affected devices to Johnson
Controls under the RMA program.
Humidity Unreliable
The zone humidity reading was reliable
and has now failed.
1. If the source of zone humidity was the
onboard sensor, contact Johnson Controls
product sales and support.
2. If the source of zone humidity was a BAS,
check the BAS to ensure that it is still online
and providing the TEC with the humidity
reading. If removal of the BAS mapping was
intentional, reset sensors through the menu.
