Upgrading Honeywell DT90E to DT92E

[enforcer109]

I have a Worcester Bosch Greenstar-Heatslave 18-25 Combi and the room thermostat is the Honeywell DT90E.
Now I have purchased a DT92E, which I thought would be a direct replacement, however I'm not sure how the wiring should be.
Currently there are two wires coming into the back of the DT90E (brown going to A and blue going to B) seems straight forward.
However, the DT92E has two lots of connectors, each with three connections. They are N L L & A B C
It would appear that my neutral will go to N followed by the live into the L next to it.
If I am correct in my assumptions so far, what extra wiring do I need to complete ?
TIA

The two wires you have are a live and switched live, no neutral. You need an additional live and neutral fitted as you don't have enough wires at present for a wireless stat.
