Hello,
I trust someone would be able to assist - I've looked through the forum and haven't been able to find a thread close to my issue.
I'm trying to install the Nest 3rd generation thermostat with Heat link; I already have a combi boiler, Vaillant Ecotec Plus 831 with thermostat that controls both heating and hot water.
Should I just install the Nest thermostat alone and not the heat link? Since I already have a thermostat that controls the boiler.
Or do I need to install the Nest heat link nevertheless - but the question is how? Please look at the pictures attached to see the PCB of the boiler. It doesn't have the wiring as explained in the Nest manual.
I would very grate if you would clarify and explain best way to go about the installation.
Many thanks
