Packages came quicker than anticipated, so went to work hooking everything up.
Process was surprisingly straightforward and had everything working in just over an hour.
I have a question about the hot water aspect of the app though.
The app shows hot water as on between 0700 and 2200, which I imagine is the default, but as mine is a combi boiler, I can get hot water on demand at any time, if my understanding is right.
I also have the option to switch off the hot water in the app. Again, I didn't think I had any direct control of the HW on a combi other than setting the temperature.
Correct me if I'm wrong as it won't be the first time!
