WM 1013-200 troubleshooting
I installed a new WM 1013-200 boiler controller on an older WM boiler, the 1013 was listed as the replacement for the older integrated controller which died in place.
As soon as I installed it the second red LED (limit control) started flashing red.
Everything else worked well, lighes and sequence went as they shold (although the second red LED continued to flash). There were a few more restarts than I had experienced with the older unit.
Now, after sitting all summer, same light flashing but nothing happens - no startup cylce at all, no fan start, no pump start, no igniter, nothing but a green power light and a red flashing light. Have reset the power several times, reset the thermostat signal, nothing. Read some stuff about polarity, haven't tested that yet (need batteries for my multimeter) but everything worked fine on the older controler - which ran for 15 years.
