I just got one of these Ranco controllers with an old used MoreBeer conical. I am confused about the "Heating" (Stage 2) set point and why it is different than the regular set point. For managing a fermentation at say 68 degrees, why would I not have both set points at 68? What is the general best practice? I dont want it to be substantially lower and risk the beer dropping 4 or 5 degrees before it starts to heat up again! Also the MoreBeer setup guide recommends 2 degree differential but 1 seems more precise obviously. Why the 2 degree default?
Innersanctum Holdings Inc. on Mar 12, 2018
BEST ANSWER: Leonard is correct. We recommend a 2 degree differential so that your cooling device, such as a refrigerator/freezer, isn't turning itself on and off too often. It is also recommended that your heating and cooling devices have different temperature set points to eliminate the possibility of both devices trying to engage simultaneously.
Is this wired up in a manner that I could plug in a large refrigeration unit that has a compressor which pulls 12 amps?
Brent Tanzy on Apr 7, 2018
BEST ANSWER: The specs are: Full Load Amps - 16 @ 115VAC, 8 @ 230VAC. My opinion is, if the compressor runs at 115VAC then it should work.

An Excellent Controller
I used my controller to maintain 70 F in a small enclosed space containing four 5 gal carboys of fermenting wine. It was set to cycle a small heater on and off to maintain a constant temperature in the space to enable malolactic fermentation. Variance was set at 1 degree. The Ranco controller performed flawlessly over a six week period when the fermentation finished. Outside temperature varied from 20 F to 60 F.

I highly recommend the prewired Ranco Digital Temperature Controller Controller. Excellent value.
