Folks,
I have a Johnson A419 controller jumped in factory default settings that I'm using with my brewhemoth conical to control the pump for the IC. I have it configured with the following settings.
SP: 66F
SF: 1
OFS: 0
ASD: 1
DIF: 1
What I'm expecting is that the controller will try and keep the temp at 66F with a differential of 1F, so when it hits 67F it will turn on the plug until the temp reads 65F and then shut off with a minimum 1 min delay between cycles.
What I'm experiencing however is that once it hits 67F it will actually chill all the way down to 63F before shutting off. Am I misinterpreting how this controller works, or is it indicative of an problem with it?
