Hi all, I purchased a new thermostat for my Vailant Ecotec 831 combi boiler.
I currently have a danfoss thermostat with timer fitted using a 2-core cable from the boiler as shown below using the blue and brown wires from terminals 3 and 4. When checking these using a multimeter the live is showing as 240V.
This image shows how the danfoss was wired up when the boiler was fitted.
The new EPH thermostat looks like this but am unsure how I should connect this up using the wiring coming from my boiler.
And this is the only wiring diagram supplied in the box:

Could someone advise me on this please?
Thanks in advance
