Heat resistant cable 2 wires LS and LR to Com and NO on Nest e heatlink. Providing there’s no zoned heating.
Its currently wired through a programmer with the LR and LS link in, should i just remove the programmer and use the LR and LS connections? It needs a wire for the DHW though

If you have separate hot water (I’m not up on oil combi’s and how they work), then leave the programmer in , because you’ll then have a separate switch for your heating. Remove the link at ls and Lr and replace with your 2 wires from heat link
