Hi, I have just moved into a house with a Worcester 35cdi boiler, and it currently has a built in programmer on the boiler and no room stat. I want to add a Siemens RDH10-rf to give a bit more control. I have found the connection on the boiler which requires the link to be removed and the thermostat connected to, but am unsure which connections to make in the RDH10-rf? I know I need to supply 240v to L and N, but then I have Lx, L1, L2. I have the two wires coming from the boiler from the st8 block which are maked Ls and Lr. What i need to know is where do I termininate these two wires in the Siemens. i.e. Does Ls connect to Lx and Lr to L1?
Any advice would be great!!
