OpenTherm programmer stat etc

[SSE]

Wired all the usual for a boiler a while back, room stat in lobby & programmer in kitchen. Was an old boiler which has now packed in. They’re putting a new boiler in which apparently has OpenTherm connections, it’s an Intergas boiler. I’ve connected to an OpenTherm boiler once before & the controls consisted of a receiver beside boiler then & wireless programmer stat. My question is, are there controls & a room stat I can replace existing with to connect to OpenTherm or will I have to get rid of programmer in kitchen & fit a wireless programmer stat like I done previously?
