I have Google nest third generation connected to Viessmann boiler
through open therm.I am having difficulty with heating as the boiler
never goes on full capacity even if the house is cold! The boiler
supports opentherm technology.
I have just installed nest learning thermostat today.I am having an
issue with the thermostat temperature readings which is 3-4c above
actual room temperature!I reset it hoping it would fix with no
effect!!Any advice before I return it?
Hi,Many thanks for your replyI compare it to Viessman boiler thermostat
& Aqara temperature thermostat, both of them give same reading which is
3-4c below the nest thermostat!Yes it shows time to achieve target
temperature, which I have to set 4c abo...
