Pressuretrol Setting
DK_5
Member Posts: 18
I have a Honeywell PA404A pressuretrol (Additive differential) on a Weil-McLein SGO-4 boiler. Both are new in August 2006. I have the cut in on front set ay 0.5 psi but I am confused about the differential dial . I want it set at 1 but do not know where the dial should be. Should I see the #1 or should it be under the arm to the left. If it is under the arm I see the # 2. Please advise.
Thanks
Thanks
