Control for pool heat exchanger

Davco

I am hooking up a Phalen heat exchanger to my boiler (WM ultra 230)system. I would like to utilize my multizone relay controller (Argo ARM 6P). I need a 24 vac water stat to wire into the controller to start the boiler and circ pumps for the heat exchanger circuit. Any help appreciated.

You could use...

...a tekmar 150 Setpoint Control.

You can look at an L4006A1959 from Honeywell - it does not do all the functions of a Tekmar but it is cheaper in price

I'd lean

toward any thermistor type setpoint control. Make sure it has an adjustable differental setting that allows a fairly tight range.

I prefer the brands with large digital displays. Tons of choices out there. Johnstone Supply catalogs 4 or 5 different brands.
