Introduction

Your KE2 Therm controller has the built-in capability to receive firmware updates over Ethernet. To perform this update over the network you will need to place your controller in Bootloader Mode, and then use the Firmware Update Utility provided by KE2 Therm, as described below.

Placing your controller in Bootloader mode suspends normal controller operation & allows the controller to receive a firmware update from the Firmware Update Utility. The Firmware Update Utility runs on your local PC/laptop and will discover any KE2 Therm controller that has been placed in Bootloader Mode. Then you can apply firmware updates to your KE2 Therm controller via your wired network.
