In this video I upgrade to a 3rd Generation Google Nest Thermostat to control my Viessmann Vitodens 050-W combi boiler. This will be a super in-depth video where I cover On/Off control, OpenTherm control, hardwiring the thermostat back to the Heat Link and share a couple of tips and tricks around mounting a Nest onto a standard back box and how to stop the Nest preheating a combi boiler.
