Changing Thermostat????

[Ripperoo]

My 20+ year old current Sunvic TLX room stat has 3 wires going to it (plus earth) and has been tested as follows:
#1 Yellow - Switched 240v
#2 Not Used
#3 Red - 240v
#4 Blue - Neutral

I have an unused Danfoss RMT230 room stat (wiring diagram below) and wonder if it be a compatible replacement for the old Sunvic TLX I currently have?

Would it be a direct swap, using the colours mentioned above (yellow, red and blue) in the positions/numbers shown below on the Danfoss RMT230?

The RMT230 is designed to, as the name suggests switch 230V. (Your diagram shows 24v)

So in your case, the RMT230 would connect as follows:

Live (red) goes to 1 'COM'
Switched live (yellow) goes to 2 'ON'
Neutral (Blue) goes to 'N'

Duh! Of course it is! How did I not even notice that?

I wouldn't, care but I was sure I pulled that image from a PDF downloaded from the Danfoss site after searching for "RMT230", so don't know how I ended up with that particular diagram. Weird!

So in your case, the RMT230 would connect as follows:

Live (red) goes to 1 'COM'
Switched live (yellow) goes to 2 'ON'
Neutral (Blue) goes to 'N'

Thanks for that info Stem, it is much appreciated, but still cannot believe I never even noticed the "24v" at the bottom of that image. LOL

Cheers, worked a treat!
