It doesn't programme ons and offs, but temperatures.
You can set temperatures and time periods.

I read the instruction leaflet. There's no mention of "off" for the new controller.You can set temperatures and time periods.
I would tend to agree. However, finding a heating engineer who does the analysis and arithmatic doesn't happen. It's always "this looks like it needs ..." based on their previous experiences.Then you wouldn't put the stat in the lounge. Systems need designed properly with correctly sized radiators in each room and the stat fitted in the correct place.

So the idea is to select an area to work a wall thermostat, the original idea was a room with no outside doors, and no alternative heating including sun light through windows normally kept cool so on warm days it will turn off the system, and that room would not have a TRV. However in real terms such a room rarely exists.
Using the hall has a problem as when the front door is opened you want fast recovery, so it needs a TRV and wall thermostat carefully set so after door is opened the TRV will reheat hall fast, but reduce the rate before it gets warm enough to turn off wall thermostat, so it will only turn off wall thermostat on warm days. I did this with mothers house so can say it does work, however it took some time to adjust to work well. And if you want as I did varying temperatures through the day you need both the wall thermostat and TRV to be programmable.
Are today's intelligent systems really a benefit to anyone other than the manufacturers and their shareholders
