Hello I am new to the site, looks like a great resourse hopefully someone can be of some help. I just wired a second zone to my boiler. I installed a Taco SR503 switching relay to both pumps and according to the diagram given I wired it for a Tankless boiler with zone 1 priority. When I turn everything on the L7224 aquastat calls for heat, the zone 1 pump turns on and It calls for the burner to fire, however the burner will not start. Nothing on the burner motor turns on its like I have no voltage, the diagonstic signal light is not on and pressing it will not to anything. I have 120 power at B1 on my aquastat, and nothing at B2. I left the jumper between TT on the burner motor, not sure if i still need it there but removing it did nothing either. Its a weil Mcclain tankless boiler with a Beckett burner, I dont have the model of the burner infront of me but I bought the whole package unit less then two years ago. Any help would be greatly appreached

Thanks
-Mike
