Nest Hot Water wiring....

[1986jay]

Hi all,

Just after a little help with the hot water wiring.

Ive installed two heatlinks for heating only and all working well.

I have attached the programmer wiring which controls the water.

Now unlike a conventional programmer...this programmer controls hot water and towel radiators.

Am I correct in thinking that I connect to 6 on nest and link 5 to the live?

Thanks in advance

Sounds about right.

If the hot water is presently wired to the 'hot water on' terminal (3) at the Honeywell above, then yes as you have figured, it will need to go to the Heatlink (6) and you will need to link the Heatlink (L) and (5) terminals.

If there is a wire presently connected to the Honeywell terminal (1) 'hot water off' that will need to go to the Heatlink (4) 'hot water satisfied' Don't worry if there isn't one, not all systems require it
