Capability Installation Instructions
43
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 is 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 by 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.
Changeover Fail The Supply Temperature Sensor is not
installed, has failed, or has been
disconnected and the TEC can no
longer detect changeover mode to cool
or heat.
Follow the same steps as Supply Temp Fail
alarm.
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. 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.
Controller Fault The controller has detected an internal
fault that it cannot recover.
Order replacement units and return the affected
devices to Johnson Controls under the RMA
program.
An unknown error has prevented the
controller from turning on.
Order replacement units and return the affected
devices to Johnson Controls under the RMA
