Thanks for the guide,
Just had this one fitted to a new combi boiler, in the morning the boiler is told to come on but if the it only needs to make up 2 degrees from room temp of 19 and stat set to 21 will the boiler slowly heat up the radiators so to prevent over shoot. I ask this because the rads never got hot.

Got one of these and it point blank will not control my Viessman 100.
Only way to switch it on is through the ViCare app. Showing as binded but still won't work.
