pressor is opened.
The estimated airflow from indoor subsystem
B0

is near to 0 CFM.
Estimated airflow from motor is lower than
B9
Eb9
the airflow requirement.
Control board does not have the necessary
D0

data for it to properly perform its functions.
Control board does not have the appropri-

ate data needed to properly perform its
functions.
The airflow requirement is greater than the

airflow capability of the indoor subsystem.
There is a mismatch between the shared

The memory card data has been rejected.
This test is required at startup.
Installer should navigate to the thermostat

menu to run SYSTEM START-UP TEST.
This code will clear once testing is complete.
Description
• Overload protection (OL) sensor inoperable
• Jumper wire (X33A) is put in incorrect position
or off
• Failed indoor blower motor
• Indoor fan motor not properly connected
• Too much static pressure
• Failed indoor blower motor
• Indoor fan motor not properly connected
• Too much static pressure
• Outdoor unit is wired as part of a communicating
system and integrated control module does not
contain any shared data.
• Outdoor unit is wired as part of a communicating
system and integrated control module contains
invalid shared data or network data is invalid for the
integrated control module.
• Outdoor unit is wired as part of a communicating
system and outdoor unit requires airflow greater
than indoor unit's airflow capability, or a type of in-
door unit without EEV is connected to the system.
• Shared data is incompatible the system or missing
parameters
• Communication wiring with indoor unit has loose
connection.
• Airflow trim setting is out of range. See "SET
THERMOSTAT TO ADJUST INDOOR AIR CFM
TRIM" section.
• Shared data sent to integrated control module
does not match hardware configuration.
• Shared data on memory card has been rejected.
Items below are messages only displayed on the thermostat screen.
• Incomplete SYSTEM START-UP TEST
• SYSTEM START-UP TEST is running
Probable Causes
• Check resistance on OL sensor to verify operation; Replace if
needed.
• Check OL sensor position on compressor body.
• Check jumper wire position (X33A)
• Check ID fan motor wiring and connectors; Repair/replace if
needed
• Check ID fan motor; Replace if needed
• Check the obstruction inside duct work.
• Check ID fan motor wiring and connectors; Repair/replace if
needed
• Check ID fan motor; Replace if needed
• Replace control board if necessary
• Replace control board if necessary
• Check combination to be matched with rating list; correct if
needed.
• Verify shared data is correct for your specific model; Repopulate
data if required
• Check communication wiring and power supply wiring of indoor
unit. Repair as needed.
• Verify trim setting and adjust if needed.
• Verify shared data is correct for your specific model; Repopulate
data if required
• Verify shared data is correct for your specific model; Repopulate
data if required
Run the SYSTEM START-UP TEST.
