Honeywell T5001A

This gas valve is now obsolete, SURPRISE! No replacement from Honeywell or any I can find. They are working, and I would like some doc. on them. Basically to find the number/temp assignments. #1 - #9 = ??? As I am setting up the system with a Tekmar 256 and strap on aquastat, Id like to have info on this valve. Thanks, Geno.
