there is a micro switch in each zone valve , when it fully opens it tripps this switch turning on the gas valve ( i know there are electronic controls , high /low limit switches ect ect ect , for the sake of this post humor me ) ...so the valve opens and the heating of the water starts ........ so you have a bad micro switch or a broken wire from that(#1) zone valve . i dont know anymore what numbers on the valve connections control that but look for wires that go from valve to valve and then to the boiler one my be broken . other wise you need a zone valve .. ps:....you might try just removeing the cover and look at the switch the valve may be a little stuck and open its just not reaching the switch , a nuge from a well placed screwdriver might free up the valve Last edited on Tue Oct 20th, 2009 08:02 am by Cactus Bob ____________________ SORRY ABOUT THE SPELLING , I FIX GREAT , I DON'T SPELL WELL |
