Hi All,
I have just spent all day trying to fix this issue but with no luck. It was installed by a specialist and was working fine until someone worked on the boiler ever since then I have had this issue and I can't seem to resolve it.
My system is a Saidie Heatrae electromax which is an Electric wet flow system with hot water storage cylinder.
I have two BDR91s , 1 connected to hotwater (Hotwater valve only) and the other is connected directly to the boiler(boiler wireless relay) and I have 4 radiator valve zones and each with an HR92UK. My configuration is similar to Figure 4 in the installation guide. There aren't any motorised valves on my setup.
Whenever I switch on the hotwater , the BDR91 for C. heating also comes on. I have read on here that when set as a "boiler relay"
, this switches on both hotwater and the boiler. I have also tried setting it up as a heating valve but nothing happens when there is a demand for hotwater.
What configuration am I to use to prevent the heating coming on when hot water is switched on ?
