controlling a circulator

I have a hot water fin and tube setup and I need to know the best way to wire circulator pump. I have a High and Low limit and the circulator runs until the low switch opens . High limit shuts burner down . Even if t stat is satisfied the circulator runs until it reaches low setpoint on switch . The house has been this way for 30 years but My buddy says there is a better way . One circulator is all I have . Thanks

    What your saying doesn't make since. It could be a smoked control. Maybe I'm missing something in your post. What is the manufacturer and model of the control. Do you still use the boiler for domestic hot water.

    Just my personal opinion but I think you have a great pump control now. This control prevents condensation by allowing the boiler to warm up above the condensation temperature, and by letting the pump run at the end of the cycle, you are purging the extra heat from the boiler and putting it into the house instead of letting it overheat the boiler room or just go up the chimney, and it can help cut down on temperature swing in the house.
