Aquastat L8148E , Utica MGB75HD set temp
What temperature should I say being relay to. I did have it I believe on 135 but since it has been very cold I did raise it to 180. I was trying to get my temperature to use from a graph that a outdoor reset controller would use. I do not have one. Seems my relay has one high settings on it. Also my hot water is not hooked into my gas boiler. Current is 19 degrees outside. Takes awhile to get this place heated up the past 2 nights.
