    Have a ariston boiler system boiler.
    Drayton RTS1 room stat and a drayton Lifestyle LP112 programmer.

    I want to replace the RTS1 with the honeywell DT90E - I believe the system uses a neutral to switch @240 mains also in conjunction with this lifestyle timer.

    So do I need all 3 wires to new Honeywell or can I just use 2?

    The DT90E supports mains and low voltage so I just want to know wats the best method of doing of this please?

    PS- some posts regading this are unclear with regards to my scenario so apologies to those who have supported this issue more than once!.

    Thanks for the info, can i make the neutral at stat side"safe" and leave the other side connected, simply as i do not want to open up the junction box its all wired up too.

    Thanks

    Yes, put it in a connector block.
