Worcester Greenstar 30CDi Combi boiler with Nest

pal57_2

Hi,

I've been having trouble trying to install a Nest Thermostat (3rd Gen) to my Worcester Greenstar 30CDi combi boiler.
I can't even get the heat link unit to power when wired from the boiler's output power.

Does anyone know where I'm going wrong?

Any help or advice would be appreciated.

The wiring is right. What are you expecting the Heat Link to show when powered?

The L&N of the heat link need to go to the L&N of the boiler and the calling and common from the heat link need to go to LR and LS.
