Thank you so simply explained I've had my new boiler since April been struggling with the thermostT watched your tutorial and I'm now sorted so informative well done you !!

Thankyou but after you have done your program won't you be setting it to MANUAL from Auto ?

What’s wrong with an off and on button?

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.

I think it depends on the boiler. My Vaillant has something called Comfort Mode which heats the radiators up slowly (and cools them down slowly when the heating goes off). I think that mode can be turned off via the settings on the boiler itself. Don't forget that when you pick up the remote control to change the temperature or programme it, the heat from your hands will increase the temperature on the display by at least one degree (when I reprogrammed mine for the first time it went up from 20 to 24 degrees!). Therefore if yours was at 19 when you picked it up to 'fiddle with it', it might have reached 21 by the time you put it down and the heating wouldn't come on until the temperature drops below 21 again.

In auto mode when I set the temp to 16 degrees it keeps reverting back to 21 degrees how do I change this pls?

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.
