My Johnson Controls Mizer has weakened and isnt functioning anymore. I bought a Field Controls like the one you have in this video. I also have this Weil McLain boiler. Wondering how to switch the vent damper with the new one. Seems like they have the same molex.

I have a used vent damper and would like to check it out before using. which 2 wires open the damper and which two close it. e.g. black and green seem to be power sources as they come from the transformer ( unless one is the ground from the transformer) and the red and yellow seem to complete a circuit - the yellow could also have power since it travels trough the thermostat HELP!!!

Do you know how to bypass the vent damper using a jumper on the Aquastat Relay outlet? Which two lines should connected? Red to Black? Assuming that the Vent Damper is faulty, a correct jumper on the Aquastat Relay should make it work, right?
