I am looking to add a room stat to our basic CH only system, we currently have a Grasslin old style timer I have purchased a Salus rt500rf roomstat and I am confused how to connect I understand I need to connect it inseries with the timer, but how do i locate which terminals on the Grasslin? Please help :(

you may want to repost this on electrical forum where you will be told ch controls are a part-p controlled service which can legally only be done by a member of a 'competant persons' scheme.
Your rf rcvr. needs mains links to supply its workings plus contacts need to break the mains 'call' wire between timer and boiler, easy for a 'leckie' so shouldn't cost much to get done properly.

Although heating engineers and gas fitters can work on the electric side of a heating installation up to the fused spur - without Part P.
