Replacing a triple aquastat relay yo a electronic aquastat

Replacing a triple aquastat relay type L8124A, C L815A because the relay went and won't run the circulation pump. Replacing it with the L7224u electronic aquastat. Looked online for a wiring diagram to switch from one to the other. Anyone know where I could find my that wiring diagram on how to go from one to the other. Been looking for the exact same one L8124A online but rather not pay 650 bucks for one and find a used one.

    The L7224U will do exactly what the L8124 does. The identification of the terminals is the same. Just follow the wiring diagram in the instructions of the L7224………..you did read the manual……….correct?

    Carefully disconnect the L8124 so you know which wires went to which terminals.

    Takes about one hour if you're fast. 😁

    The only thing you won't like is the single spade terminal. I just wire to the screw below it.
