Switchmaster 900 tado wiring

[daf12234]

Got an old switchmaster 900, bought a tado to change it bust just a bit stumped on the wiring. Mainly because there is no off for the hw and ch. This is what I've got behind the old timer. Any help would be appreciated, thanks.

You don’t need hot water off or heating off as you have a 2 port spring return valve setup known as an S-plan. Wiring should be straightforward.

Cheers, just wanted to sanity check before I cock something up
