I have many pumps in my system:
Boiler return circ
Primary Loop circ
House (secondary) Loop circ
Barn Primary circ
Barn Secondary circ
Storage loop circ (boiler side of HX)
Storage loop circ (tank side of HX)
DHW circ
More to Come.
All pumps are Grundfos 15-58
I just want to turn them on/off at certain temps. The Honeywell aquastats are so expensive I'd love to find an alternative. Is there one?
