Honeywell Smart Valve model identification number

wrd0225 Member Posts: 1
I don't know how to identify which model Honeywell smart valve is in this heater. There are no numbers are letters that I can see. I also don't know which wires to test for for what voltage. Do I test the blue wires separately, between what points? I nee the step by step, if possible, with pictures.

    Make Model and Serial numbers help! There should be numbers on the Smart Valve itself.
