Bosch 2 wires Idle Valve

[65looter]

Hello everybody,

I've been looking thru the forum, but cannot find it.
I have this valve:

It's a 2wires, how do I connect it? I mean pin 1 is FIDLE output or pin2?

thanks for your help.

pin 1 is 12V, pin 2 is gnd (MS fidle). This valve is open at 0, closed at 25% DC and should regulate at ~40%DC. It is used in Bosch LH2.4 systems. (not LH2.4.x). It is in this schematicas item 272:
