Hi everyone.
I have an old Honeywell T40 room thermostat.
At the moment, wires feeding the thermostat are as follows:
Brown - to terminal 1
Blue - to terminal 3
Earth
Now looking at the diagram on the T40 casing there should of been a third wire neutral. Not only that, but it looks to me like the wires above should of been round the other way, but I'm guessing as it's a switch it doesn't really matter.
So, onto the RT500RF. We have inside terminals for N/O, Com, L and N.
Here is what I think I should be doing.
The brown goes to Com
The blue goes to N/O
Thanks for any re-assurance or suggestion.
