    The one in 4 the blue is neutral and not used with nest e, so I fold them over and tape, or put on a connector block or crimp, out of the way, so 1 red should be line in so to top common and 2 yellow to centre N/O (normally open).

    remember that any existing timers the CH will have to be set to constantly on and the nest E will override it

    Eric mark thank you for the advice, the nest e heatlink is battery powered and It says it does not need any 240v wiring just wanted to clarify which ones I will have to terminate in the terminal block that comes with the fixing/installation kit pleae

    As said, you don't need the blue, don't connect it and terminate it safely. The red and yellow go to C and NO.
