The unit seems good, but two problems, one can't set distance for geofencing, two does not connect to any other temperature monitoring device. So as a result a bit basic.
So the idea is, the wall thermostat in winter never turns off, and the TRV's control the room temperature, except for when there is a programmed temperature change. The thermostat is only there to turn the boiler off when we get warmer weather. So the TRV in the room with the wall thermostat is set lower than the wall thermostat, I did this with mother's house with a gas modulating boiler, and it worked A1.
However, in this house, the hall cools too slow, and every other room is either not used all day, or has doors to outside, or has an open grate or cooker so alternative heating, so the basic problem is there is no single room where the wall thermostat can go, which is the average temperature of the house.
So what I need is a second thermostat, however also renewing the double glazing, so have delayed seeing how that changes how rooms compare.
The point is each home is different, so there are few systems which will suit all. And main control is the TRV heads. Any on/off control each time it turns off and on again resets the boilers' logic so it starts again assessing output required, and we lose that 11% latent heat while it works out best output level.
The boiler monitors the return water temperature, which reflects how much and many radiators are turned on. And the radiators are controlled by the TRV's which lower than most of the radiator and slightly to one side are in a good location to monitor return air temperature, the wall thermostat height is dictated by building regulations, all about being able to see and manipulate the device, not the best place to control room.
