I've just installed the Nest Thermostat (2020) to connect with my boiler. I've gone through the set up and despite setting the Heat to Off (confirmed on the Nest and in the Home app), the boiler is constantly in Space Heating mode and my pipes are hot. It worked properly with my old thermostat. Only when I pull the Nest off the base plate does it shut off.
