    Furnace Relays for Circulator?
    Hello,
    The question is about Heating Relays.
    I want the heating Circulator Pump to run without starting the furnace and running the furnace all the time the pump is running. I need some info about relays I could use for this project.
    So, when the thermostat sends the signal to the relay, the pump should start not the furnace.
    Any suggestion, opinions info’s are welcome.

    Thanks

    You can wire a swiching relay from power &ground to a pump but if you have a l8124a tripple aquastat control that maintains a low temp on the boiler it will start the unit when low limit is reached
