Danfoss HSA3 Mid Position Valve Wiring

[alx]

Hi,

I had a faulty actuator which I have now replaced, however I have lost the original wiring diagram that I made when removing the old unit from the junction box in the airing cupboard.

I know that the blue is neutral, and the Br-Wh is live.

I think that the grey wire went to HW - on

But, I'm not sure where the orange wire went - ???

Can anyone help ?

The programmer is a Salus EP200 if that makes any difference to anything?

or, should the Br-Wh wire go to the room stat and the grey / orange go to the cyl stat on / off ???

from memory, gray is HW off, orange to HW on (call from cyl stat and switched live to boiler) Br/W call from room stat. the instuctions that come with the valve should tell you all this.
