Introduction

Your KE2 Evaporator Efficiency (KE2 Evap) 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 boot-loader mode, and then use the bootloader program 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 bootloader program. The bootloader program runs on your local Windows PC/laptop and will discover controllers in the same network that have been placed in Bootloader Mode. You can then apply firmware updates to your KE2 Evap via your wired network. Do not attempt to update controllers over Wi-Fi.

Getting Started

To perform a firmware update for your KE2 Evap controller, you will need:

• The controller you wish to update
• 110V/220V power source for the controller, as appropriate
• A Windows PC/laptop to run the firmware update utility
• The bootloader program was downloaded from www.ke2therm.com (See Preliminary Steps).
• Ethernet cable(s), to provide wired network connections between the controller, PC/laptop, & the KE2 Smart Gate (if used).
• (Optional) KE2 Smart Gate to provide network connections for the controller & PC/laptop.
• (Optional) KE2 Edge Manager (KE2-EM) and KE2 Switch to provide network connections for the controller & PC/laptop.

   NOTE: Due to browser caching, it is sometimes necessary to start a new browser session, or use Incognito/ Private mode to load the webpage correctly.

   • 1a Click KE2 Evaporator Efficiency to open the “Device Info” window. Confirm Firmware Version is now 20302v5.00.

2. Using the screenshots collected from Part 2 Step 4, log in and change any values on the Setpoints page that were changed to defaults during the bootload process.

   • Note: the controller will be in Intro mode after bootloading, the same as if you installed it for the first time. If no setpoints need to be changed, click Save on the Setpoints page to accept default values, and allow the controller to begin operating.
   • Login to make changes, default credentials are as follows:
   • Username: ke2admin
   • Password: ke2admin
   • For security, the Password MUST be changed from default upon first login. Once the Password is changed, log in using “ke2admin” and the new Password you just created.
   • IMPORTANT: Due to security improvements in v5.00, your browser will likely display a privacy or security warning when first connecting to the controller. See the next page.

When connecting to the controller via its IP address, a privacy or security warning will likely appear in the browser. If the IP address of the controller is correct, depending on the browser, click “Advanced” or “Show Details” then“Proceed to…” / “Accept the Risk…” / “Continue to…” / “…visit this website” to continue to the controller webpage. It is generally not advisable to click past this warning, however, proceeding past this warning when connecting to the controller is safe.
