Intergas Xtreme 36 modulation with Tado

Options

Yesterday I had my 15-year-old AWB Thermomaster replaced with an Intergas Xtreme 36. On my old AWB, once the modulation was set via EBUS (D07 on Tado), I could see the modulation temperature of the kettle on display. Now with the Intergas, the setting has been changed to D01 but when I click on the radiator icon on the Intergas, I see a static temperature. I am now wondering whether the Tado is actually modulating. Is there any way to confirm this? Also, any good advice on changing some settings of the boiler to better integrate with the Tado?
