Hello there,

I've been working hard to find a Professional to assist you with your question, but sometimes finding the right Professional can take a little longer than expected.

I wonder whether you're ok with continuing to wait for an answer. If you are, please let me know and I will continue my search. If not, feel free to let me know and I will cancel this question for you.

Please note, I am just a moderator for this category, I can only try and find experts to help, I can't answer the question itself.

Thank you!

Adam

Do you want to run me through the wires you have in the original and their connections.
I am guessing red, blue, yellow, green and yellow?

from left to right, the Honeywell t6360 is wired as follows


1= earth


2= neutral (blue)


3= 2 x black wires which look as if they come from the 4073 hot water/


heating valve.


4= empty


5 = live (brown) which looks as if it comes from a timer control panel


 


The Honeywell cm907 has 3 possible wiring connections


one says neutral, one says live the third is blocked but looks as if it is designed to have a link to the live connection. The cm907 is battery powered and apparently doesn't need an electrical supply.

Normally, if it is battery powered then all it does is link a couple of connections together.
If this is the case then there is no need for the neutral or earth if there is no connection.
A - in
B - out
