Hi there, im not an experienced electrician but wanted to quickly exchange a thermostat for my electric under floor heating. However the wiring arrangement is different on the new one.

I think I know how they match but would really appreciate it if someone could tell me if I have got this right.

On the attached image, I have drawn the numbers in Red to match the numbers on the original diagram to show what I think maps to where. Would someone Kindly tell me if I have got this right?

Many thanks, really appreciate it!Screen Shot 2018-01-11 at 3.53.40 pm.png
 
Best you tell us what you think the connections are ..... All the information is there in front of you!
 
Thanks Murdoch, what I was hoping for was someone just to validate I've got this right or tell me I've got it wrong.

ie, if I put the wires that are currently in location 1-6 into the equivalent slots as I have numbered in red on the new diagram, does this map correctly?

I appreciate that I am novice and if the advice is get a qualified electrician in to do it then fair enough. I wasn't expecting to find a different arrangement when I went to swap them over so just trying to be pragmatic.

Thanks again
 
L in 1. N in 2. mat in 3 and 4. floor sensor in 5 and 6.
 
Looks Ok to me..

Before you connect, good idea to do a continuity/resistance and insulation resistance test on the probe and the element.
