What do all the thermostat charts mean, and can they help,

[ericmark]

My thermostats shows and and and they look very pretty, but is there any point, is there any way these can be used to improve economy or comfort? I have used to help set the lock shield valve, but the first 4 can't see why they are even shown, but I am sure not provided just to look pretty on the app?

With respect, you do seem to vastly over complicate your thinking on heating controls.

I have a new boiler with manual TRV's, except in the hall where the Hive is situated. That's all, and it works perfectly fine. I have never balanced the system and I have no idea what the flow/return temps are.

My wife has the app on her phone, only to turn it on remotely, I don't have the app. It gets too warm we turn it down, it gets too cold we turn it up. It couldn't be any simpler.
