Sunvic TLX7501 Thermostat

[MWSB3346]

Hello - my Drayton Combistat seems to run all the time so I have bought a Sunvic TLX7501 Thermostat - but I need help with the wiring ??
The boiler is a Potterton Combi 80, and the existing wiring for the Drayton is 3 wires - these are still connected to :
L = Live
3 = Load
N = N I presume neutral/negative

On the Sunvic there are 3 ways but it seems to only require 2 wires ??

Can anyone clear this up ?

Thanks
Miles

seems it does not require a neutral, as the contacts are engaged using batteries. See the posts above.

Thanks - so do I just pull the N from the block on the boiler and connect the L into 3 as constant and the switch live into 1 or 2 ?

All sorted - thanks

Would the moderators please refrain from splitting posts without leaving an explanation? Read my post above - it now makes no sense. I know nothing about this thermostat, I was repeating what had been said above in the original thread, I dont want to be held responsible for a DIYers mistakes (though the source of my advice seems to have been correct)
