Worcester Bosch Greenstar 30si - No Power to Tado

Hi all,

Have wired up my V3+ extension kit to the boiler following the instructions within the app for the Worcester Bosch Greenstar 30si, wiring into Ns Ls LR terminal block as per attached but on switching mains power back on, the extension kit doesn’t seem to be receiving any power at all.

Boiler operating fine as usual for hot water, no central heating currently as the MT10RF timer has been removed as per app instructions so isn't communicating with the WB thermo as expected.

Are the instructions wrong? The Tado ones match the wiring diagram for external thermostats in the boiler manual. Have I got a dead unit?

    I've been looking at the wiring for a Greenstar 30Si boiler this week, with Tado wireless controls, for a family member. The Greenstar manual has 64 pages of installation, commissioning and servicng insructions. Your wiring colours kinda look right. However, you'll need to check the live and neutral feeds to the wired or wireless stat, to and from the controls.
