I have a heat exchanger that is hot water from my boiler via a circulator pump. The circulator pump is controlled by a relay. I have two wires next to my heat exchanger that: if I close the circuit, the circulator pump goes on sending hot water to the heat exchanger, and if I break the circuit, the circulator pump turns off, closing off hot water to the heat exchanger. I need to find a proper aquastat that is going to do just that, break the circuit once the water passing through the heat exchanger reaches certain temperature, and makes the circuit once the temperature drops below certain threshold. The water being heated is the pool water, just to clarify.
I saw some honeywell units that are supposed to do exactly what I need them to do, but I need a suggestion on which model exactly and how to wire it, thanks in advance!
Is this a home made system or commercially sold ? in any event look to the solar side of the aqua-stats and temp controls setups, they work on the lower temperature grades, as far as a standard aqua-stat it taps into the return line, they are less sensitive to the lower temps like for a pool, mainly used on water heater return lines that operate over 100 degrees, you'll need to pipe in the well that accepts the aqua-stat probe. 2 wires splice in to the pumps power. most important is were you locate the probe, distance from pool, return pipe material, outside temp etc, degrees lost via distance traveled.
