Firmware for Pro Series control system

We regularly update the software for our control system to add new functions and features.
The update is now done via WiFi (from version 1.01.00)

When a new version is available, your system will automatically download the update and let you know when it's ready to install. The Micro-SD card must be installed in the system as temporary storage for OTA updates.

How to update manually

- Get an empty MicroSD card, formatted as FAT32
- Create a folder called "UPDATE" in the root of the MicroSD card
- Copy the *.bin file to the "UPDATE" folder (remove other files in folder)
- Turn the system off, and insert the MicroSD card into the slot on the control box
- Turn on the system, and wait for the update to complete. 


If you get the error message "Error 01", the system has problems reading your MicroSD card. Try again 1-2 times.
If it doesn't help, please try another MicroSD card. Contact us if you're still having problems.
