Connecting Evohome to Worcester RI for modulation

[diselsamm]

Good afternoon
I am expecting delivery of the Evohome ATP926G3001 package 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? Is Greenstar Ri Open therm compatible?

My understanding is I need to connect a Worcester Bosch EasyControl Adapter or similar bridge to the EMS 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

Sorry to say you can’t as it’s a heat only you would need a system boiler

Hi, I am not sure I understand this. The Ri has an EMS plug and is able to modulate.
