I don't mind what I get if I'm honest because I know very little about these devices. If the gas man turns up with a keep it simple stupid smart thermostat I'll be equally as happy as getting an all bells and whistles flagship device.
I asked for the best so it'll be interesting what he decides. I did say all bells and whistles. He took a quick look at my set up, asked me some questions then off he went happy as a Larry.
Questions,
Are you getting heat
Are you adjusting the trv
Is the water ok
Heating generally working away from the thermostat issue
Radiators getting hot
Temperature of the heating on the boiler
All of which I could answer phew! I told him no to another dial thermostat. So that's definitely not happening.
I like that display you have. Very nice
