Hi I have just purchased a new VRT360 digital room stat and have tried linking it to my ecotec831 boiler but I get nothing on the display.

I have connected it using the old cable for the old thermostat making sure only the same two cables are connected to the boiler and the stat using the ebus connectors.

Do I need different cable for the ebus?
Does anybody have any experience of ebus controls?

I assume the control get's it's power using the ebus connection.


Any help would be gratefull?
