The ETH03 firmware is NOT the same as the UCM firmware of the baseboard. The ETH03 firmware runs on the ETH03 submodule module and not the UCM.
The UCM Firmware is the firmware on the UCM Baseboard (marked by UCM 7.xxx label). UCM Firmware is upgraded by right clicking on the UCM in Modules and selecting "Check for Upgrades" see http://www.comfortforums.com/forum92/3400.html
ETH03 Firmware runs on the ETH03 submodule,
The 'Upgrade' button is used to upgrade the ETH03 firmware on the submodule over the network. Firmware upgrades are available from the Cytech Technology website at http://www.cytech.biz/eth03_firmware.html
There are 3 zipped .hex files available
ETH03-General.hex is for UCM/ETH03
ETH03-client.hex is for UCM/Universal
ETH03-heatmiser is for UCM/Heatmiser (wifi)
After downloading the zip file and unzipping, select the ETH03-General firmware (.hex file).
It is advisable to check the website for the latest ETH03 firmware and upgrade the firmware before use.
In Comfigurator, go to Options > Settings > UCM Connections
Select UCM Interface= Network (Local)
Click on the link for Comfort Server Manager (in blue)
Please upgrade the UCM firmware to 7.060 or above before upgrading ETH03 firmware to 2.14 or above
If ETH03 firmware is 2.14 and you are not able to connect to the UCM/ETH03, please downgrade ETH03 firmware to 2.01. This should allow you to connect to the UCM/ETH03. Upgrade UCM firmware to 7.060 (or above) then upgrade the ETH03 to 2.14 (or above)
I have CSM 2.0.6 which will not connect upon refresh, and doesn't have a refresh button! I cn find Comfort on the network very easily with other tools. UCM07 is v 7.028, comfort v 7.057, configurator 18.104.22.168. Is ther a version mismatch here?
