Keezer Controller in F?

LBussy · Mar 15, 2013

All of the "economy priced" controllers I see in the write-ups seem to be centered around the imported controllers that use readouts in C. I'd prefer, if I can do so for not too many dollars more, to do one with a readout in F.

Are there any heat/cool controllers suitable that are F and similarly priced?

You can look for a CN9000A on ebay. Can get them sometimes for under $40. They do both C or F. Depending on the model you may need a SSR for one of the outputs but it can be used. Can get an SSR pretty cheap. There are a lot of different versions of the Omega's that will work just fine it is finding them for a good price. Once you find one you can search the model number on the omega site and see if it has SSR built in or is DC pulsed witch will require an external SSR. Some have both. I have a couple different ones so if you are interested PM me.

Great googley-moogley! Those are expensive new!!!! Looks like the CN9111A is the one with two relay outputs. > $200 on the Omega website.

I'm beginning to see why the eBay controllers are so popular.

If you really want F you can't beat a Ranco

EDIT: I just saw you want heat/cool which the Ranco won't do. There aren't many cheap options for that which is why everyone is buying the ETC-1000 and sticking a conversion chart next to them.

Just snagged a CN9111A for $29 on eBay:

Used but guaranteed to work. Good enough for me!

Good score! Not much more than the cheapo and a much better unit.

Also make sure to zero it when you get it so when you use the PID setup it is more acurate. Also out 1 is 5A and out 2 is 3a. Most people asume they are both 5a
