SUBJECT: Bluetooth® Shared Data Loader
We are excited to announce the release of a new tool that will eliminate the need for shared
data chips with ComfortNet™ products.
Now, with a one-time purchase of the Bluetooth Shared Data Loader, you will have access to all shared data files for Goodman®, Amana® and
Daikin® brand products via the cloud.
2025 UPDATE: The shared data loader is only needed if the control board does not have a built-in Bluetooth adaptor card or chip.
Confirm the control board before recommending use of the SA-031 tool.
These shared data files can be accessed when using the
Bluetooth Shared Data Loader with the CoolCloud™ HVAC App.
ComfortBridge™ products feature built in Bluetooth and do not require the use of this, Bluetooth Shared Data Loader
This process is spelled out in the instruction below or can be found at
https://www.coolcloudhvac.com/loaderuserguide by scanning the QR code below with your
camera on your smart device:
To order the Bluetooth Shared Data Loader (part # BTSDL01) contact your Goodman or Daikin
Customer Service Representative.
Listed below is the instruction for quick reference. Happy loading!

Connecting to the Device:
Turn the Bluetooth® Shared Data Loader on by switching the Power Switch to the ON position.
The blue Status LED should begin flashing periodically. If the CoolCloud™ HVAC app is open,
it will detect the new Bluetooth network and display “SharedDataCard” as an available network.
Tap on this network to connect.
If the network does not appear, ensure the Status LED on the device is flashing and tap the
refresh button in the app to continue scanning for networks.
If the app requires any security verification, choose “Pair Device by Code” and enter the code 123.
Reprogramming Shared Data:
To select shared data, click on "Shared Data Card" on the system overview screen.
Then click on "Shared Data".
From here, the appropriate Shared Data can be selected by either scanning a barcode that can
be found on the unit or by typing in the model number of the unit. If possible, scanning the 2D
barcode is recommended to get the most accurate results. If this barcode is faded, damaged, or
can’t be found, then it will be necessary to enter the model number instead.
The 2D barcode can typically be found somewhere inside the unit. For indoor units, the barcode
can typically be found on the blower deck. For outdoor units, it can typically be found on the
inside of the control board compartment. This 2D barcode will always have the model number of
the unit printed next to it.
For this ComfortNet™ furnace, the 2D barcode is located on the blower deck,
its model number is AMVC961205DNAA
After selecting the desired model number, the app will present a confirmation screen. Review
the information on this screen, then, if the information looks correct, click “Confirm and
Continue” to program the selected Shared Data onto the card.
If the information shown on the confirmation screen does not look correct, it may be necessary
to choose a different set of Shared Data. Return to the previous screens and ensure the model
number provided in the app is correct. If possible, use the camera to scan the 2D barcode
instead of manually selecting the model number from the list.
Loading Shared Data onto the Equipment:
Once the Shared Data has been programmed onto the card, determine if the equipment being
worked on is a ComfortNet™ unit or a ComfortBridge™ unit. All ComfortBridge units have
Bluetooth® and are designed to work with the CoolCloud™ HVAC app directly. In most cases,
it will be easier to simply connect the app to the Bluetooth network of the unit and reprogram
the Shared Data on the unit directly from the app.
NOTE: When searching for shared data, all model numbers are listed with an asterisk symbol
for minor revision. Example: GMVC950905CX A*. You will select your corresponding model
revision combination from this list to download onto the BTSDL01.
In some cases, it may be necessary to load Shared Data onto a ComfortBridge unit (e.g. when
the Bluetooth connection is not working). If this is the case, please skip to the section labeled
“Loading Shared Data onto ComfortBridge Equipment” for further instructions. Otherwise,
please keep reading.
Loading Shared Data onto ComfortNet Equipment:
When loading Shared Data from the card onto a ComfortNet unit, first disconnect power from
the HVAC system and insert the card into the Shared Data loading connector on the control
board inside the desired ComfortNet unit. When plugged into the unit, the card must be
powered on to function properly.
The reprogrammable Shared Data loader card must be
powered on to load Shared Data onto a unit
With the card plugged in and powered on, power on the equipment for 30 seconds to allow the
Shared Data loading process to complete. When complete, power the equipment off and
retrieve the card from the unit. Reconnect power to the system and confirm that the Shared
Data loading process was successful, and that the system is operating normally
Loading Shared Data onto ComfortBridge™ Equipment:
To load Shared Data onto a ComfortBridge™ unit, first insert the card into the Shared Data
programming connector on the control board inside the desired ComfortBridge unit. Then
ensure the board and the card are receiving power. Once the board is fully powered on and
displaying the “IdL” code, use the “LEFT”, “RIGHT”, and “CENTER” buttons on the control board
to navigate the appropriate menus on the control board.
Press the “RIGHT” button until the display reads “Cr”.
Then press “CENTER” to select the Cr menu. Some codes will begin flashing on the display.
Ignore these codes and hold down the “LEFT” and “RIGHT” buttons simultaneously for at least 10 seconds. If the display switches to “Cr” again, check that the Bluetooth® Shared Data
Loader is inserted fully into the connector and is powered on.
After holding “LEFT” and “RIGHT” for 10 seconds, the display will start flashing a new code
(“dnL”), once this new code appears, release the “LEFT” and “RIGHT” buttons. The equipment
will display the options “YES” and “no” to confirm or cancel the Shared Data loading process. To
confirm the process, press the “RIGHT” button to select “YES”.
Then press the “CENTER” button twice to confirm the selection. The board will then start the
Shared Data loading process. Once the Shared Data Loading process is complete, the display
will return to displaying “Cr”.
NOTES:
What is Shared Data?
There are many different models of equipment offered under the ComfortNet™ and
ComfortBridge™ platforms; however, all these models use only a small handful of control
boards. To make sure each control board can work inside its intended chassis, we load each
board with a small amount of chassis-specific data when the equipment is assembled.
When the equipment is installed, this chassis data is copied over to any other connected
communicating equipment and saved there in case some parts need to be replaced at a later
date. Because this data is shared by other equipment on the same network, we call it “Shared
Data.”
This means if only one part needs to be replaced in a system, it’s likely the Shared Data will
automatically be loaded from the existing equipment. However, if multiple parts need to be
replaced all at once and the system loses all the places where this Shared Data is stored,
Shared Data will need to be reloaded to make sure the freshly installed parts are compatible
with the existing equipment.
When is it Necessary to Load Shared Data?
In short, if a unit reports a d0, d1, or d2 fault code, it will be necessary to load Shared Data from
the card.
One of these fault codes may be generated by a unit after some parts of the equipment are
replaced. After a system is powered on for the first time, there are two or three places where the
Shared Data for the entire system is stored. Shared Data is always stored on the indoor unit
control board and the indoor blower motor. If the outdoor unit is a ComfortNet™ outdoor unit
wired in communicating mode to the indoor unit (i.e. wired using the 1-2-R-C connector), then
Shared Data for the system is also stored on the outdoor control board.
Shared Data will only need to be replaced if all sources of Shared Data on a system are
replaced at the same time.
Loading Shared Data can be avoided by replacing only one of these parts at a time and
powering up the system in standby mode after replacing each part. Standby mode refers
to powering up the HVAC equipment without a call for heating, cooling, or constant fan
from the thermostat.
UPDATE: The shared data loader is only needed if the control board does not have a built-in Bluetooth adaptor card or chip.
Confirm the control board before recommending use of the SA-031 tool.
