Default Digital Temperature control for Keezer

I know there are all kinds of threads on this which might be why it's so confusing for me. I'm looking for a digital temperature control to mount on the front of my keezer. I don't need it to have dual controls as I'll only use it for controlling the cooling of my keezer. Since it'll be on the front I would really like it to read in Fahrenheit. I found this one on eBay which is a a good price however I have no idea if it will work or not. What do I need to look for to make it work for my keezer? How many amps? Is a certain brand better than another? Etc?

http://item.mobileweb.ebay.com/viewi...id=02207948898

Sorry for being such a noob. If it wasn't for resources such as HBT I would never even attempt to try something like a keezer.

The item you referenced is an "AC 220~240V Digital Temperature Controller Thermostat F". Note the operating voltage, probably not what you really want if you're in the USA.

If you go back to eBay and search for "STC-1000" you'll find a controller that is available for 110VAC service that is pretty popular here...

Cheers!

The link you posted is for a 240 volt controller. You need one for 120V, be sure to read the fine print. You need to know the current draw of the freezer, the relay in the controller may not be large enough to handle it but it depends. Worst case, you'd have to add an external relay and have the controller turn it on & off. Otherwise you're on the right track.

As the others have said, make sure you get the 110v version. The 110v version of the one you posted is the exact one I used for my freezer. The eBay listing states it's a 5A relay, but the paperwork with the controller indicates it's 10A. I'm using it on a 7-8cf freezer with no issues (it's been running for a couple weeks now, working great!).

Here's a link to one from the seller I purchased from - Link

The STC1000 reads in Celsius. I've had mine for over 6 months and I've gotten very tired of converting all the time. Fahrenheit just makes more sense to my American mind. I initially installed a heater in my fermentation chamber but have yet to need it. I plan to convert over to a single stage controller soon.

Just ordered a pair of these 110vac, single stage, fahrenheit controllers:

If you end up going with the Ranco ETC, check out the video I just left in this post on how to wire it up. You'll have no trouble at all!

here's a pic of the controller's Fahrenheit readout. I couldn't attach it to the PM we had going.

I've got the 220v celcius version of this controller. I'm running 120v through it and it powers up fine, but I think my freezers draw amperage during startup is too much for the switching circuit. I'm trying to find a relay that will work but something this size is just too big for the project box I used to build my controller.

I've got quite a bit of store credit with Grainger but I'm absolutely lost on which relay to use.

If anyone has any suggestions, please feel free to suggest them from the Grainger catalog

Can someone confirm for me that this is what I need and will work fine. My 7.2 cu ft freezer reads 5A on the sticker. I currently reside in NC so the 110VAC is what I need correct.

Lastly, is this a decent price for the unit?

Thanks in advance!
