A Benchmark Boiler equipped with the Intelligent BootLoader will look for the Benchmark files
and always pick Item #3, the BMK firmware file with the most recent version number. An
Innovation Water Heater will look for and always pick item #4, the Innovation firmware file.
NOTE:
The Intelligent BootLoader is backward compatible with earlier firmware versions; it will load
firmware files named edgeImage.hex if it can’t find the relevant BMK or INN file.
In addition, the Unit Settings screen now contains a Product Type parameter, which
displays either BMK or INN, depending on which firmware type is currently loaded.
Preparing for Firmware Update
Complete the following steps to save the unit’s current setup, which includes the current state of
all settings/parameters. The setup will be restored only if necessary, as described in Section
6.2.7.5.
1. Remove the unit’s front panel, to expose the USB port on the Controller’s left side.
2. On the Edge Controller, go to: Main Menu → Advanced Setup → Unit → Settings
