The old Sunvic unit is playing up it's the (2nd one we've had), and the valve is very stiff (Valve is 20y.old), so I've drained down and replaced the lot with a Danfoss HSA3 body and head I had lying around (New in box)
But before I wire the head up I just need some clarity on the wiring.
The Sunvic has the following: Blue, Orange, Grey, White.
The Danfoss has: Blue, Orange, Grey, Brown/White
I'm assuming that the White and the Brown/white are interchangeable?
From what I can see of the Sunvic in the connector block:
Blue is neutral
Orange is shared with pump live
Grey is shared with a black which goes back to the cylinder stat
and the white connects to a yellow, which goes to either room stat or programmer.
Thanks
