Just about to order my evohome parts.
Question about the opentherm. I have a Y plan wiring.
I will be fitting the HR92 to the radiators, I believe if you fit opentherm to the boiler, then you dont require BDR 91. I have Unvented hot water cylinder.
How is the hotwater controlled without the BDR91 fitted, TIA
