Converting new build 2 zone heating to Opentherm

Options

Hi all,

Just moved into a new build 3 bed semi, we have a Ideal Logic ESP1 35 boiler (opentherm capable). Currently running on two zones (upstairs and downstairs thermostats) heating their respective zones.

After a bit of searching the kit they've installed is this: https://www.esicontrols.co.uk/product/cpc2zpc/

These are the valves (handily located under the bath!)

i currently have 1 wired thermostat, 1 eu wireless receiver and a STRV for all rooms and wireless thermostats for each room.

How can I reconfigure this for opentherm controls?

Thank you in advance.
