    I am just about to replace my thermostat with a 3rd Gen Nest . I have a Franco Belge Idris Exclusive combi boiler , with a simple thermostat. But am struggling with the wiring on the Heatlink .
    I'm going wire the L and N (on the Heatlink) from the boiler no problem then bridge the L to 2 on the Heatlink . I just need to know how to find the 'call for heat' to wire 3 . I'm replacing the wired in thermostat by going 'wireless ' so won't need T1 and T2 , as the new control will be plugged in elsewhere
    But I guess I'll have to close of the original Thermostat wiring too.
    Any help much appreciated

    Nous sommes en Angleterre.

    Je n'ai jamais entendu de votre Franco Belge chauffage ici.

    3+4 are the room thermostat connections.

    Whatever Brexit means, it does not seem to be going anywhere very fast!

    A recent comment was that it could take up to 10 years!

    Is that the original wired thermostat connected to 1&2 ?

    Don't be in too much of a hurry to apply mains voltages to the boiler control terminals. Safer to make a 2 wire connection to the boiler from Heatlink 2 & 3 without the short link to Live in the Heatlink.

    Heatlink 2 and 3 should be connected to boiler 1 and 2.

    Live and Neutral in boiler to Live and Neutral in Heatlink.
