Trying to modulate a Worcester greenstar 440cdi ErP
Hi, I have recently had a new boiler fitted and for various reasons it had be a greenstar 440. As I understand it Tado is able to modulate Worcester boilers through HT-BUS / EMS-BUS. The problem I’ve got is that the person who fitted my boiler has connected in Relay mode as that’s how the previous one was done. I cannot for the life of me find a gas engineer or electrician who is willing to come and change it over to be HT-BUS for me. Does anyone if this is something I could try myself or would that not be advisable? My other thought was to find someone who will do a smart heating install of another system that modulates it, then after they’ve gone I can just swap it back for my Tado. Is anyone aware of any cheap systems that do this? Bosch Easy Control is maybe the only option?
