Hi all,
I want to buy nest 3rd generation and install myself on my boiler but when I look at the wiring on nest instructions I can see that there are 2 ways to do so. One is 230v and one is dry contact.
i have attached a picture of my motherboard.
I have to wire L & N from 230V to N & L to the heat link so far nothing difficult. Then, my question is I should wire from 230V rt one line to n’ 3 on heat link and loop n’2 to L and wire the earth from 230V to the earth next to T1 & T2 and remove that loop on 24V tt or I have to wire N & L as the previous but instead using 24V rt wire in 2 and 3 on heat link?
What the difference between them ? if they both correct .
Hopefully everything is clear...
Thanks
