Hi All,Would be great if i could get some help.

Had a new boiler installed worcester 34cdi however didnt have the nest to hand back for plumber to fit so attempted to have a go myself yesterday however it doesnt seem to be working correctly.

I have connected it in the following way (below), the heat link is connected and powered and clicks when i change the temperature however it doesnt actually turn the boiler on ?

connections are in the image and below.

(boiler) Lr - 3 (HL)
(boiler) Ns - N (HL)
(boiler) Ls - L (HL)
(HL) L - 2 (HL)

To help narrow things down.
Does the boiler work (Fire Up) if you remove the heat link wires from terminals Ls and Lr and refit the bridging link in the boiler.
Also, I assume there are no other timer controls fitted to the boiler.

Yes the boiler fired up still if I manually set the roads to a higher setting, currently it’s just set to frost as I don’t need it on right now. However when I tested changed the temp to really high to see if the boiler would come on it didn’t.

No other timer controls

Look for a guy on YouTube called Thomas Nagy. he just uploaded a video on installing a Nest thermostat. He's a qualified sparky and really good.

Edit just found it. I hope it helps.

Is that the correct link as it refers to the installation of a Hive stat.

You've wired it right :salute:

The Heatlink terminals are notoriously bad for getting wires in I usually use ferrules.

If you can use a meter make sure you have 240v on terminal 3 on heatlink and LR on boiler just in case it's a physical issue
