WeatherTRAK Controllers get new features and firmware updates several times per year. Make sure your controllers are on the latest firmware for best performance and to ensure compatibility with all the features on WeatherTRAK Central and WeatherTRAK Mobile.
The latest Bootloader version (shown as “BL” in the control panel) for all controllers except Pro2 is version 220.127.116.11. This version of the bootloader is included with all firmware updates for 7.8.2 and 8.4.2 and later.
To deliver the latest firmware version to your controller over the air, you’ll need to install the Cloud Update Key in the controller. All new controllers shipping as of April 16, 2018 already included this key.
Note: The WeatherTRAK ET Pro2 does not support the Cloud Update Key.
