Danfoss remote Thermostat

[kinnockthecat]

Hi

Had a search through the forum and couldn't find what I was really after....

I want to replace my old Drayton Digistat (no idea of model number) with a Danfoss RT51/RX1 wireless remote stat.

The connections on the Drayton are as follows....
1 = L Red wire
2 = Dem Yellow wire
3 = Sat (no wire)
4 = N Blue wire

The Danfoss wiring diagram for the RT51 receiver is leaving me a little perplexed....

There are six connectors and I have 3 wires....
The Danfoss connections are as follows...

N = Electronics
L = Electronics
1 = Zone 2 on
2 = Com
3 = Zone 1 on
4 = Zone 1 off

Wiring diagram also states:
For mains voltage operated systems link terminal 2 to mains live supply

I tried connecting my Red wire to L and the Blue wire to N and the yellow wire to 2 (Com). It all appeared to work (it didn't go bang!!) however the boiler hasn't fired when a demand for heat is established.

The red wire goes live when the programmer is advanced to on. I also swapped the yellow wire to 3 (Zone 1 on), still ok but the boiler not firing.

Presumably if I link the terminal 2 to terminal L this will work ok? And connect yellow wire to terminal 3 (Zone 1 on). Leaving the blue on terminal N.

Anyone on the forum familiar with these?

Cheers

On the new stat:

blue wire to N = electronics
Red wire to L = electronics
yellow to 3 = zone one on

The you need to fit a red link wire between the "2 = com" terminal and then "L = electronics" terminal.
