That's the purpose yes.

You're running your controller in Cooling/Cut-In Mode then. In that mode the output relay is energized at Setpoint and de-energized at Setpoint - Differential. It works just fine that way as you've found, it's just a bit less intuitive (imo) as you have to do math to calculate your target temperature

You could switch to Cooling/Cut-Mode by moving the Jump2 jumper so it covers both pins (connecting them together). Right now that jumper is only on one of the two pins so the circuit through them is "open". See page 7 of the manual...

Cheers!

Thanks day tripper, That's what I figured. Strange they would ship it as cut in mode by factory default instead of cut out. I intuitively set it thinking it was in cut out mode. I am eager to try the stuck on insulated probe.

Curtis you using a chest freezer as well? I understand your need for two controllers if so. I just use mine for cold storage. I use my standup fridge for lagering. When set to the warmest temp i get 50 F inside then I can usually adjust it with the built in controls with accuracy anywhere down to 45 F so it works well for me. BTW i ordered parts for two spunding valves based on your build.

Yes, I have a small one for ferm (w the two controllers) and a big one for storage w just one external controller. Built in tstat would work fine for this since it covers fridge and freezer range, but I already had the extra controller and its handy to actually dial in a specific temp. I sometimes use the big freezer for ferm too if the small one is in use. Planning to add a second small one next season so I can have two ferm chambers.
