Wiring a Worcester 32cdi compact for EMS

retrospek

Hi all,

I could really do with your help to make sure I'm not doing something stupid.

I want to switch my set-up over to using EMS on my Worcester 32cdi boiler - as currently it isn't.

I'm assuming based on the pictures below I would do the following:

1. In picture 1: I would move the grey cable in the Yellow LR CH port to the EMS Port (shown in Orange on the left)
2. In picture 1: I would move the black cable in the Orange L 240 Out port to the EMS Port (shown in Orange on the left)
3. In picture 2: I would move the Black Cable in the NO port to the - port on the right
4. In picture 2: I would move the Brown Cable in the COM port to the + port on the right
5. I would set the 'Control Interface' in TADO to use D17

Can someone please confirm if that would work ? Is that all I need to do ?

I would really appreciate if someone could let me know...

I don’t know anything specific about your boiler (like whether Tado supports it for a digital connection) but that should be all you need to do for a digital connection.

Thanks - can anyone else also confirm what I've put would work ?

I'm now wondering should I also link the L and LR ports ?

Thanks for any advice anyone can provide...

And

Would love to hear the outcome here.

I have basically the same boiler, and am considering getting tado to use ems modulation.

But it is hard to find definitive info or even success stories showing the wiring used and the outcome.
