EMS Bus wiring

Looking for wiring connections and setup for Worcester Greenstar CDi Classic to enable control using the EMS Bus (If possible) I have it connected using contacts at the moment.

Thanks in anticipation

  • Hi Phil,

    I can only confirm EMS is supported by Tado (I am using it with my Buderus heater). Did you try to use their step by step install guide?

    Hi Andrei

    Thanks for the response. It didn’t give me the option during the installation process. I found a document related to wiring a Vailent to eBus and a Worcester to WT-Bus but not a Worcester Greenstar CDi Classic to eBus. It may be the same but on my boiler I only have some contact marked up EMS BUS.

    Regards

    Phil

    I would also like to know this ems setup, I’m assuming it’s a setting within the thermostat. I know the the ht-bus is d16 or d17 on the thermostat and does this need a Worcester adapter converter thing
