Ok so I've been reading everything I can and think it goes as follows....
N -> Nest N
L -> Nest L
1 -> Nest 4 (hot water satisfied)
2
3 -> Nest 6 (call for heat HW)
4 -> Nest 3 (call for heat CH)
If that's all correct then what do I need to connect the hot water and central heating commons on...
Hi
I've purchased a 3rd gen nest to completely replace a horstmann centaur plusc27 programmer. It's controlling a mistral boiler and we currently do not have a thermostat.
The wiring is just to complicated for me to work out. Could anyone help with what wires go where on the heat link...
