SECTION 6 – ADVANCED SETUP

6.2.7 Firmware Update

When AERCO releases a new Controller firmware version, there are two options for obtaining it;
both require the firmware to first be downloaded to a USB device:
Option 1: Download it to an external computer and then save it on a USB device – See
Section 6.2.7.2: Download to an External
Option 2: Download it via an Ethernet cable directly to a USB device plugged into the side of
Controller – See
Controller
Once the firmware is on the USB device, that device is then plugged into the side of the
Controller and the Controller then performs the update.
However, the procedure for upgrading the Edge Controller also depends on the current version
of the BootLoader, a component used during firmware updates. The Edge Controller on all new
Benchmark Boilers and Innovation Water Heaters are equipped with the latest AERCO
Intelligent BootLoader (V1.00 or later), however some older Benchmark units may still contain
the original BootLoader.
There are 3 ways to tell what BootLoader Version you have.
Main Menu → Diagnostic →System →
1. Go to
shown on the 2
2. If the BootLoader screen blinks white, the version is older than V1.00
3. While the BootLoader is running, its version is displayed in the top-left numeric display.
If your Controller has an older BootLoader, you can obtain the BootLoader Upgrade Kit, P/N
69335-10 from AERCO, then install it per the instructions in the Technical Instruction Document
(TID-0219) included with the kit.
NOTES:
A BootLoader update is not mandatory. The older BootLoader will work, however it will not be
able to use named files shown below; instead it must always use the file named
edgeImage.hex. Additionally, the unit may not support all USB device types. If the BootLoader
update is not performed, ensure the that your USB device works in the Edge Control by
listening for the beep when it is inserted, or going to
Network → USB Storage
The Intelligent BootLoader automatically distinguishes between Benchmark Boiler and
Innovation Water Heater files loaded on the same USB device, and then loads the proper file for
that unit. The Firmware file names are stored onto the USB device in the following format:
•
BMK_V509014_Boiler Firmware
•
INN_V509014_Water Heater Firmware
The Intelligent BootLoader looks for the appropriate file on the USB device and looks for the
most recent version of that firmware. For Example, a USB device could contain the following
files:
1. BMK_V509014_Boiler Firmware
2. BMK_V509015_Boiler Firmware
3. BMK_V509016_Boiler Firmware
4. INN_V419017_Water Heater Firmware
