Hi,
We have a nest gen2 heatlink which only has 5 connectors N L 1(satisfied) 2(common) 3(Call). The boiler was connected to 2 and 3 but during some building works it was disconnected. We now have a Heatmiser UH4 and we are going to connect the heatlink to zone4 for radiator use.
The UH4 just has 4 terminals too, N,L,E and SL. Can anyone advise how to wire the two together? Obviously the L and N goto the relevant terminals, and i presume SL goes to the call for heat, but is there anything else? I found a diagram on here for the nest gen3 but that has a lot more terminals.
Thanks
Paul
