Replacing Drayton Digistat SCR + LP522 with Tado

Options

Hi,

Moved into a new house which has a Worcester GreenStar Danesmoor 25/32 oil boiler which is controlled by a Drayton LP522 timer panel with separate controls for hot water and heating. A Drayton Digistat SCR is paired with an RF601 room thermostat.

My plan is to leave the LP522 to control the hot water as that's a pretty static task, but remove the Digistat SCR and RF601, replacing them with my Tado receiver for heating control.

I have pulled the cover on the Digitstat SCR to see the wiring (photo attached). Can someone help me understand how to connect that same wiring to the Tado receiver please?

Thanks in advance!
