So I got a johnson dual stage controller (http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1
) to hook up to a keezer that I am making. I got it wired up today and was testing it. All is well and it's working as expected except for one problem. The relay that is set to Cool won't allow me to set it below 50*F. What gives?
I checked the manual and manufacturers website and don't see any way to change this. I noticed that the "Heat" relay can go all the way down to 0*F which seems odd to me.
The manual says that this controller supports a temperature range of -40*F to 300*F so I'm hoping this isn't a bad unit or something.
Like I said, the relays switch on and off just fine, but I can't figure out how to get the cool side temperature to the correct level.
Any help is appreciated. Thanks in advance.
