I am looking for a wire diagram for a Honeywell M204A modulator valve. If anyone has one or could point me in the direction to find one that would be great.

    I didn't find an M204 anywhere. Could it possibly be a V2045A? That's the only thing I see at all close. It's a motorized powerhead for a V5045A valve body.

    that is from a Honeywell engineering manual from 1954. I started running service in 60 there was still quite a bit of series 10 around then. I don't remember seeing much series 20, I think it was pretty much obsolete by then. bob
