How this termostat will keep the temperature? I have it connected to a BDR91 and Zone Valve that is keep opening and closing, making a very unpleasant noise. Thanks

Hi, I am getting an Evohome ATP926G3001 package shortly this week. Is it possible and how exactly can I connect the the Evohome system to a Worcester Ri boiler to convert it to modulization? My understanding is I need to connect a Worcester Bosch EasyControl Adapter or similar to the EMS bus on the boiler and to the BDR91T. Is that possible? I am also not 100% sure I can use a Worcester Bosch EasyControl Adapter for a Bosch RI boiler, what else could I use? Thank you very much
