Installation wiring help

Hi there
Tado just sent me really generic instructions.
I've got the wired thermostat which is going into a combi boiler.
I'm replacing a Sunvik SL
The wires are N L and 4.
On the tado instructions that is p1 (N) and p2 (l) and there's no 4 sticker.
But then wiring into tado it has No nc com then 3 blanks and the instructions just say the striped stickers go I to the blank areas. But there are 3 so which?

  • A standard installation would usually be something like L to NO, neutral to a park slot and the black wire to COM.

    There are completely generic instructions here if that helps. https://cdn.brandfolder.io/607DGEMS/as/7k4rssnm8hbmr6mjf94qmck/104210-DIGITAL-ST01IB01-INSTALLER_MANUAL-TA-EN-00-V3.pdf
