Installation Instructions

Finding the Current Software Version

Before starting the software installation process, the current software version may be determined as follows:

Downloading the Software Update

For Series B controls, software updates are provided over-the-air (OTA), or uploaded manually using a microSD memory device. The following instructions apply to the manual update process.
You will obtain best results using a MicroSD card that is between 4GB and 32GB in size, and formatted as a FAT32 device. Any other formatting (NTFS, exFAT, etc.) will result in an error of “please insert MicroSD card.”
To perform a control software update, follow these steps:

• Click on this link to obtain the updated software:

http://cacbdpapps.net/marketing/eula/Evolution_Connex_Control_V0417_eula.html

If the link does not work properly, copy the link into your browser web address window and open the link.
NOTE: You may NOT distribute the software itself. You may only distribute the link to the software, or this document.

• Read the End User License Agreement (EULA).

• At the bottom of the EULA, choose “Yes” if you accept the agreement. If you do not wish to accept the agreement, you will not be able to download the software update.
  NOTE: EACH user must accept the EULA each time the software is downloaded. You may NOT distribute the software itself. You may only distribute the link to the software, or this document.

• Once the file has been downloaded, open it in WinZip. Select the TSTAT folder, then the Unzip to action.
  NOTE: The names of the files in the images below are examples, and will change with the latest version numbers

• Choose the MicroSD memory device as the location to which to extract the folder from the zip file. This will create a new TSTAT folder, or over-write the existing TSTAT folder and any files contained within it. Click Unzip.

• Verify that the files, including the hex file, have been extracted into the TSTAT folder of the MicroSD device. Note that the “USER” folder is where the photo and schedule files would be stored.
  NOTE: The names of the files in the images below are examples, and will change with the latest version numbers.

Next, eject the MicroSD from the PC and go on to the installation, below.

Installing the Software Update

• Select system control software update.
  Note: Some systems may include HVAC equipment capable of accepting a software update, but that is not covered in this document

• Plug the MicroSD card into the bottom of the control. If this screen continues to appear, recheck the device and formatting. See the download section.

• If the .hex file is stored properly on the MicroSD device, this screen will appear. If the screen says, “Please insert MicroSD Device”, remove the MicroSD device and re-insert. If it still does not show the screen, below, go back to the download part and retry.
  NOTE: The names of the files in the images below are examples, and will change with the latest version numbers. Press yes to continue with the software upgrade. The upload and installation will take several minutes.

• When the software upgrade is complete, a “successful” message will appear.

• The control will perform a restart after the done button is pressed. There will be a longer than normal delay for the wall control to restart since part of the process at this time is the completion of the new software installation. Once the control has successfully restarted, the MicroSD device may be removed.

• This completes the software upgrade process. You may want to confirm the new software version, as described above.
