New A419 Johnson
« on: July 01, 2013, 09:22:52 AM »
OK, I'm the new and proud owner of a Johnson A419 controller. I also bought a thermowell to use with the probe. My questions are about the settings. I'm thinking the temperature should be fairly stable with the probe and thermowell inside the fermentor - I can't imagine any wild swings negatively impacting the ferment or the fridge's compressor as 5 gallons of beer shouldn't change temps all that rapidly.

So, first - does that sound reasonable? Second and third, etc -what settings do others use for set point, differential and anti-short cycle delay?

Thanks and hope every one enjoyed the NHC. Look forward to having you here in Grand Rapids next year.

Yep

Second and third, etc -what settings do others use for set point, differential and anti-short cycle delay?

Set point is the temperature you want the beer to be held out so will vary depending on what you're doing and your preferences.

I set my differential to 1 and my anti-short cycle delay to 10 minutes.
