Best direct replacement for old Landis & Staefa Room Thermostat

[Tiggy1955]

We have a very old Landis & Staefa room thermostat which I would like to replace with a simple like for like model. I cant see a model number on this so just have this image.

Can someone recommend a suitable replacement please?

Is it a 2 wire or a 3 wire ?

A very good question - I'll have to remove and get back to you - thank you

It appears to be a Landis & Staefa model RAD1.N which is a 3 wire type (ie L in, L out, N and E)

Here's some images from the inside. Model RAD1.N Looks like 2 wire. Can't see an earth wire?

Oh, yes. I'm wrong - sorry! 👎🏻
Just as well you checked!

Two wire to replace it with then.
