Hi, I am looking link a 3rd gen nest to my ideal logic c35 boiler. I have wired the Heatlink to the boiler and the mains, however, I believe there is an issue somewhere. The Google thermostat (not wired into mains, voltage too high) is connecting to the Heatlink and it seems to be sending a demand to the boiler (sound of ignition etc) but the boiler doesn't seem to be pushing this out to the radiators.
Old connection to ESI thermostat
Heatlink
Boiler
Any help would be appreciated
