Salus IT500 to Drayon Wiser wiring

[JCGD]

Hey,

 

I recently purchased a Drayton Wiser multi-zone kit to replace an existing Salus IT500 system (This was installed in the property before we moved in).

 

I have attached the current wiring for the Salus system, the left white cable is from the isolator switch and the right white cable goes to the boiler.

 

Can anybody assist with the wiring to the Drayton Wiser system?

 

I'm wiring to a single zone heating system with a combi boiler (Ideal vogue C40 max) - This is the One Channel part of the wiring diagram.
