So I picked up one of these yesterday used for $100. Heating and cooling unit I guess. Had it plugged in all night in the basement and it reads 70 on the nose, but honestly I haven’t put any other thermometer in it, just what the unit reports out itself.

Anyway, trying to determine how many beads I should use in this thing. It’s considerably larger than my old vinotemp unit, which basically runs at whatever the room temp is because the thermoelectrics decided that they need to keep everything at 54 degrees all the time, so I leave it unplugged.

I have two of these I’ve been using in the vino. Surely I need to use more, but how much more?

Does it need to have a fan? I know it has an internal one already. Wouldn’t an additional fan need to cycle on and off on some sort of schedule to be effective?
 
Ah didn’t realize it had a fan already. That should suffice. Just need to circulate the air a few times a day to keep your RH stable and even throughout the unit.

I went with this old thread to determine how much beads.


I decided to run my fans constantly. The humidity stabilizes very fast after digging out what I want. Like within a minute.

Personally I wouldn't rely on the built in temp/hygrometer. Get a govee that can be calibrated w a salt test. I plan do do mine every 6 months or so.

It’s my understanding that the internal fan only runs when it cools (mine is a cooling only). If the ambient room temp is, for example 72°, and your unit is set on 70°, that fan isn’t going to run very often.

I decided to put two 2-inch fans inside. I have one on the “floor” and one on the “ceiling”. I ran them out to a timer that kicks them on once an hour for 15 seconds. In my Florida environment, this has worked flawlessly. Your environment may yield different results…🤷‍♂️

I put a couple of those fans in my Aristocrat above the built in fans on the Set and Forget canniseters as they weren't powerful wnught to circulate sufficiently. They were cheap enough that I just have them run all the time. They run on independent power so I could always put them on an Alexa plug and set up a timer routine if I want to in the future. Since having them in a probably 3 or so years ago, my cab is consistently +/- 0.5% from top to bottom.
 
I’m in process of making a timer controlled small fan to run off a 9v battery so I don’t have to run any wires. But I might see if I can’t find an old rechargeable lithium style phone charger battery to use instead.

The way it would work, is it runs for a select amount of time, then turns off for 24 hours and then repeats. I will probably just place it at the bottom in the battery pointing up. But something other than an alkaline battery would be more ideal.

I need to do some current measurements to try and figure out how much draw the fan will take, so I can determine if it’s going to run for 2 days and die, or 2 months and die.
 
Still working on this. I’ve sent a note to the manufacturer to see if they can guide me in how the heating/cooling might oscillate and turn on the fan. Being how it’s in a Michigan basement which barely ever gets above 65, I think it will run a bit.

Cool thing is the temp/humidity gauge that it comes with is almost spot on with my ThermoPro.

If I come up with a decent solution, I’ll share of course. :)

Now if cigarpage would just ship my order so this thing isn’t empty..I’d take some pics! 😆
 
Going to table this for now. After talking with the manufacturer, it is apparent the fans turn on often enough, to circulate air, especially with a colder location.

That said, my original idea was not going to work, but I did find a work around. Unfortunately it meant some small circuit boards and a lithium battery, which would work perfect except humidity is not their friend. Especially the lithium. And I’d rather smoke the cigars then let a lithium battery do it for me. But I was able to find a suitable battery and a bms, as well as a timer to run it all. But if you have ever seen a lithium of any size go up in flame well..it usually doesn’t end too well.

I could drill a hole and wire it in like a normal person, but what is the fun in that? 😂 Maybe some day lol.
