boiler quit working changed l8148e aquastat started working quit again tested and changed s8610u module,l8148 aquastat and l4006 limet controller,boiler temp is rising and kicking manual reset 2 zones with 8 thermostats
make sure the 8148 [is that a triple?i've forgotten] limits are well below the 4006 the one with the reset i take it don,t forget if it's strap on and higher water will stack,with that many t'stat it must be commercial use
