New Tado user - questions about extending system and setting up

Hi,

Recently bought my first Tado kit, a brand new, but clearance stock V3 Smart Thermostat starter kit from Argos eBay store, for £76.99. Kit included Smart Wall thermostat and Internet bridge.

My central heating system comprised a Baxi Duo-Tec Combi 24 HE boiler, and wired analogue wall mounted room thermostat, in the lounge. There are 8 radiators throughout the house (3 bed semi with conservatory), all currently fitted with TVR's, including a towel radiator in the bathroom.

So, I have currently changed the wall thermostat for the Tado smart thermostat - a very straightforward job with only 2 wires, it took about 20 minutes including registering devices via the App.

I currently have my boiler on 'constant' setting and use the smart schedule for bringing the heating on/off. This already is better than what I had, which was basically the standard 24hr timer on the boiler. I can now control different temperatures as well as the different times.

I am now looking at getting some Tado radiator thermostats, but just a bit unclear how best to set things up going forward.

Do I keep the boiler set to 'on/constant', and then let the thermostats control as/when to call for heat?

If I have radiator thermostats, do they override the first/main room stat in terms of temperature?

Will the radiator stats call for heat for their respective room/zone independnat of the wall stat?

Cheers for any help/advice offered for a newbie.
