Crown Boiler Pressuretrol Difference L404F1060 and L404F1367

melomelo Member Posts: 36
Hi,

So I had to get my Pressuretrol replaced. Had to do this ASAP so I went around looking for the right Pressuretrol. The one that was previously installed (recent home buyer so this is from past tenants) was the Honeywell L404F1367.

I looked around but couldn't find it in the first few plumbing stores. However, one store said they had it but when I got there they had the Honeywell L404F1060. They said it was the same thing so I bought it as I needed ASAP.

Is there a difference between the L404F1367 and the L404F1060? It's currently installed and seems to be controlling the pressure fine however I have some issues with the boiler short cycling that I've talked about in another thread.

Thank you for any help

    No real difference. Both -- or either -- will be just fine.

    They are subtractive, so set the main scale (right one) to 2 psi and the differential to 1 and you should be good.
