See if you can make sense of this. Not sure why it came out so fuzzy when I attatched it. Do a quick electrical test at the pressure switch before we go further. Test from C to NO - reading should be zero v-ac. If it is 24v-ac then this confirms we have a switch problem and we will proceed. For your model the switch contacts open/close at -1.20" w.c. (translation - "w.c. = inches of water column (28"w.c. = 1 psi). Attachment: presstest.JPG (Downloaded 72 times) Last edited on Mon Dec 4th, 2006 04:47 am by hvacdrd ____________________ Tip Jar |
