Hi,
I have had the Evohome controller and hot water controller for some time now and was planning to add a HR92 to each room as money became available. My wife however bought me 4 for my birthday :-)
Unfortunately the Siemens TRVs I have, and thought I'd checked correctly for fitting, turn out to be the "trade" model and as such have an M30x1.0 thread and not the M30x1.5mm thread of the HR92. The EVA1 kit does not fit them either.
Are there adaptors out there to go from M30x1.0 to M30x1.5 so I can screw on the HR92? I really don't want to have to change all the valves in my house :-(
