Can you use standard computer fans (80mm) with this controller? Conventional logic tells me no because the fans are 5V or 6V (or similar) and controller is 110-120V, but I am not sure if my thinking is correct.

Thanks!

Default Computer fans

Computer fans are generally 12v DC. If you can locate an old wall wart or power supply from a cordless phone or something along that line that's 12v it can be adapted to run them. It will usually have some sort of coaxial cable going to the pin-the center cable will be one pole, the outer braid the other pole.

That's what I thought. I'm using an old side by side with two chambers and two controllers, so each one will also control a fan. I was hoping that my thinking was wrong, but I'll go get 115v muffin fans instead and use the computer fans for a stir plate.

i can check the chart:

65F = 18.33 C

so i round up to 18.4 C then add the .5 C for my differential. set my temp controller to 18.9 C

so if temperature drops the heater kicks back on at 18.4

anywho

here it is

also if you want a different temperature range... just change the 1st number in the upper left cell
Thanks for the chart, just posted it next to my controller

Can it cause problems if the wire is overheated? i.e. solder iron was applied to long
Unless you use a removable heat sink, you don't really want to "solder in place" or all wired up as you have done. I would think the controller would not be as sensitive as say an IC chip or smaller component.

I agree with RonRock that it probably is OK, but in theory, solder in place CAN fry your circuit board.

just got my controller. I was very surprised when i took it out of the box. It's heavier and more sturdy than I was expecting. Feels like a quality build. My parents just got back from 6 weeks in florida, so I'm dropping off the baby tomorrow and putting my ferm chamber together tomorrow. Thanks to the OP for the great find.

Default Cicuit diagram help

Hey all,
I'm trying to replace the stock thermostat in my kegerator with one of the ebay ones. I've attached a diagram of what I think I should be doing. Can someone let me know if this makes sense?

I don't think I should require heating, do I need a jumper or something for those spots?

Also, can I use speaker wire for the connections? I have some of that lying around.

Thanks in advance!

I made sure the power supply wired were all conected good. I've got power to the screws on the temp controller.

the fridge Im using claims it only pulls 1.8 amps.

man does anyone have any suggestions besides ordering a new one? I'm at a loss here ??

I think I'm going to plug it in and check to see if there's power to the cool outlet. maybe only the screen went bad...but that still means I need ot get a new one....damn !!!

[edit] BTW I've used it twice before so I know it did work at one time :-)
anyone have any idea besides just getting another one?

Have you contacted the seller and see if he will send a replacement yet?
