Apologies, posted this in elctrics, meant to put it in heating. So i have tried to move it or delete it without success.
I have an ideal classic boiler and a lifestyle LP241 programmer, no thermostat on the system. I can turn heating and water on and off separately or together.
I want to swap the programmer for the nest heatlink and then control it with the nest thermostat third gen (which says it can control hot water).
My existing programmer has the following wires.
Live
Neutral
Earth
HW ON
CH ON
HW OFF
The heatlink appears to ask for four wires, hence my confusion. It asks for CH Call for heat (i presume this means on), CH common, HW call for heat and HW common. On the basis that hte old programmer had only heating on, i have tried not having a heating common - but nothing works. What am i missing?
Thank you.
