I think after all of it we're in agreement about how the controllers actually work, other than Lusty who after all these years still doesn't seem to grasp the concept that they don't have any influence over the fridge other than powering on and off. Otherwise, just a minor difference of opinion about the importance of how quickly it drops a batch down to cold crash. 24 hours is not excessive IMO, in fact it's quite normal, my kegs take about that long to get down, and probably another day to fully stabilise. It's not something I'm concerned about because they get there, if they were stuck somewhere significantly higher like they were in the old kegerator and like Lusty had with his freezer then there would be cause for concern, which is why we both replaced the offending items. End result here is nice cold beer again, not just getting to about 5 degrees in the keg and ending up 4-5 degrees higher than that in the glass. Might work for some styles but I didn't really enjoy it much, especially with lagers.
