Nest Thermostat Installation

[Ian Tait]

Hello all

New to this forum but hoping to get some great advise. I have purchased a nest version 3 thermostat with a heat link. My boiler is a potterton suprima 40, and has what seems to be a simple 3 wire programmer. There are only 3 connections for this programmer labeled CH out, DHW on, DWH off.
On the nest heat link there is 3 wire connection for the central heating and 3 wire connection for the hot water, Can any one out there let me know how to wire this up

Many thanks

Ian

I agree, not a straightforward answer to give!
(Except give up on trying to replace the timer with the heatlink)
