Connecting Nest Heat Link to Combi Boiler

theadvocate_2

Hi,
I am not boiler engineer, so check everyting I say with qualified person.


I recently installed my Nest to Biasi Riva Model M90E.32S combi boiler. It is the low voltage one in the Nest guide.


Easy:
1. Connect 240V cable to N & L on the Nest Heat Link. (no earth on Heat Link). Can be from fuse box or even cable with plug which then goes into wall socket. That will provide power to the Heat Link.


2. Connect wires 3 & 1 from the boiler (which were the wires going from boiler to its original thermostat) to 2 & 3 on the Heat Link.


That's it !
Mine worked.
