Wonder if you can advise at all, I've had a Viessmann 050 25kw combi boiler with Weather Comp installed to replace my old hot water tank system. The installer has fitted an EPH CP4 RF thermostat and receiver connected to Open Therm, and says that they work together to control the flow temperature according to the room temp and outside temp. I thought they might clash, as Open Therm will effectively control the boiler as far as I can tell, but I may be totally wrong here.
I'm struggling to understand how that can work, I have voiced my concerns to the installer who is very knowledgeable and a Viessmann registered installer, and he is looking into it. I just wanted to get my head around the system first, in case I have any questions, and be able to understand the answers. Any help appreciated. Thanks.
