Replacing Thermostat - Danfoss RMT230 with Danfoss RET2000MS

Post by WillK » Sat Jan 05, 2019 8:55 am

Hi,

I am replacing an old Danfoss RMT230 thermostat as it has come to the end of its life and just need to confirm the wiring for the new RET2000MS.

The existing 230 looks like this:

and the wiring diagram is here (fig. 6): https://assets.danfoss.com/documents/DO ... 406039.pdf

The wiring diagram for the RET2000MS is here (RHS of p. 7): https://assets.danfoss.com/documents/DO ... 405954.pdf

So I need to connect the blue neutral from 4 to N, the brown live from 1 to L, the black from 2 to 3 and leave the Earth sealed off in the connector strip.

Is that correct?

Better asked in Central Heating. I'll move it.

In case anyone needs to know in future, I had to connect the blue neutral from 4 to N, the brown live from 1 to L, the black from 2 to 2.

It's all working now.
