I want to connect a Taco SR506 switching relay to a oil fired boiler Well Mclain WGO-3 which has a Honeywell Aquastat L8148A connected to it. How do I connect the SR506 to the aquastat L8148A? Thanks

    If all the circulators are in the 506, then simply run a thermostat wire from XX on the 506 to TT on the aquastat.

    It worked, thank you.
    One last question, although everything is working fine and just to be on the safe side. I jumped the T T at the burner, is that right?

    Usually that's right. When the aquastat closes the relay, power is sent down B1 to fire the burner.

    There was an error rendering this rich post.
