Probable Causes
The zone humidity reading was reliable
and has now failed.
The controller has detected an internal
fault that it cannot recover.
An unknown error has prevented the
controller from turning on.
The touchscreen components have
failed to initialize.
The baseboard and CPU board are
paired incorrectly. An error message
appears on the TEC indicating the
model number of the baseboard and
CPU board.
The previous upgrade has not
completed.
The previous downgrade has not
completed because the previous
version is no longer supported.
A USB drive has malfunctioned and
drawn more than the maximum allowed
current.
The Supply Fan Runtime has exceeded
the configured Supply Fan Runtime
Limit.
The Supply Air Temperature has not
increased above the configured Supply
Air Temperature Alarm Offset while
heating has been active for at least the
Supply Air Temperature Alarm Delay.
The Supply Air Temperature has not
decreased below the configured Supply
Air Temperature Alarm Offset while
cooling has been active for at least the
Supply Air Temperature Alarm Delay.
The Supply Fan Status configured for
either BI1 or BI2 has not proved within
the configured Fan Alarm Delay.
Solutions
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.
