Boiler wiring (steam)

jackzuroff Member Posts: 16
I'm having problems with my boiler. When the lwc kicks off the thermostat turns off as well. I added a water feeder onto the piping, and after seeing another thread about a similar issue being a problem, I'd like to get some input on where to start. Thank you.

    The LWCO is wired in before the thermostat. Depending on whether the LWCO is switching the line voltage or low voltage, it's an easy fix to move it to after the stat. Easiest fix would be to put batteries in the stat.
