Vaporstat Purchase - Wiring Question

Tom Hopkins

Question-

I would like to replace my pressuretrol with a vaporstat. I see 2 similiar 0-16oz models... one is the L408J1009 and the other is the L408J1025. The difference according to the manual is that the 1025 omits the "B" terminal and only has R and W, and it "makes RW" on pressure rise.

The 1009 has R/W/B terminals, and on pressure rise it breaks RB and makes RW. Is this the model that I want, and I should wire to it RB so when I hit the main limit it breaks?

Just want to make sure I order the correct model.

Thanks!

The 1009

is what you want. And you're right...R(ed) to B(lue) for BTU's...breaks on pressure rise.

Happy Steaming!

That one will

work, too. It is the older mercury model.
