My Heatlink stopped connecting this morning. It is still switching heating on and off but I can’t connect it to the Nest E Thermostat. Tried restart and reset many times then uninstall Heatlink and reinstall. Uninstalled Nest E and can’t complete the reinstall as it still won’t connect to the Heatlink (which the app is treating like a fresh-out-of-the-box install rather than one that’s already wired. I’m getting error code TH026, but can’t find any info on that. Can anyone out there help?
