- MDKKEN - 08-01-2014 When buying heatmiser UCM; the documentation states RS485 or Ethernet. Does this mean Either Universal UCM + RS485 or UCM06 + ETH02 or UCM06 + ETH03 Are all three supported? I have ETH02 currently. can I replace plugin ETH02 with ETH03 on UCM06 so i get extra features of ETH03 plus still  heatmiser if using ethernet? Also if UCM  + RS485, then I do not need netmonitor? Any help to remove confusion with greatly appreciated. - ident - 08-01-2014 For wifi heatmisers, you need UCM/Heatmiser + ETH02 or UCM/Heatmiser+ETH03 can be used for Heatmiser wifi modules, not UCM06 which is for Comfigurator and ios/android apps However we sell only ETH03 now as it replaces ETH02 For rs485 heatmisers you need UCM/Heatmiser with RS485 interface. You do not need the netmonitor. You need the UH1 for connection to the heatmisers and ucm/heatmiser I dont think the documentation mentions Universal UCM or UCM06 (unless there has been a mistake) The UCM/Heatmiser has dedicated firmware to manage the heatmiser communications UCM/Universal is meant for communications with many 3rd party products but it is not able to handle the Heatmiser because of the complexity of its protocol UCM06 is the baseboard of the  general UCM. If you plug in the ETH03 it is the same as UCM/ETH03. If you plug in the USB01 interface it is the same as UCM/USB I hope that clears up the confusion
