pump suggestion

I think I will try and acquire another 1262 to at least give it a shot.

What does the set point do exactly? I haven't had a chance to read through the booklet yet lol. I want the thing to come on at 80 and cool until the tank is 79. Is 80 the set point?

I think I also read about people blowing fuses like crazy when the flow through the unit was not sufficient?

That is the set point I am referring to. I forget the details, but you also set the variance. The chiller is more efficient with a larger variance. I don't think it likes the constant on/off duty. They do explain it in the manual.

If your using an external temp controller, I would make sure that you don't set it to turn on and off too frequently. With the apex you can control temp to within +/- 0.2F - However I think that would be a bad idea. I think the minimum the chiller permits is +/- 0.5F

Oh yeah I see. The ranco works with 1 degree F increments for the sensitivity.
