Another STC-1000 question

Hi folks! Am about to embark on my very first brew! I've been reading (and reading and reading) about home brewing and now my orders have arrived!

Here's the tough part - I live in the Philippines, and it's summer. Yup. So, I plan on making a fermentation chiller (Son of a Fermentation Chiller) using an STC-1000 digital thermostat. I have a storage room where I can keep it, with a relatively stable and cool ambient temp even on the worst days.

I know nothing about electrical stuff, so my question regarding the STC-1000 is:
1) Obviously I don't need the heating outlet, so is it ok to just have the cooling outlet connected? Most plans I see have both heating and and cooling hooked up to the receptacle.

2) Then, how do I set up the fan? I'm pretty sure i can't plug it in directly to the outlet, so what should I add to the wiring so I can use it on the 220V outlet?

If you could provide a simple, layman schematic, that would be a huge help, too!

Or, if you have other suggestions on how to keep my temp stable, that would very welcome

Cheers!

 

No problem just using the cooling part.
That depends on the fan, if it a 220V fan or a 12V fan. The STC-1000 just provide terminals to the relays.
If you search, there are a lot of wiring diagrams for the STC-1000.
Like this one.

If it is a 12V fan, you'd need a 12V wall wart. You can plug the wall wart in on the cooling part of the diagram above OR you could use the relay to break the 12V line to the the fan.

 

Thanks, alphaomega! The fans i will be using are those computer chassis fans. Can i just splice the end of the wall wart and attach the computer fans?

Better yet, can someone explain to me how they wired the computer chassis fan to the stc-1000

The easiest solution is to have an extra always-on outlet wired in your box. You just plug the cell phone charger in there, wired to the fan.

I personally like the clean look. I have a small 5 VDC charger IN the box, run to a panel-mount 2.1x5.5mm DC power jack. I soldered a male 2.1mm plug to the fan cable and just plug it in.

 

Yeah, I am considering having the fan always on, considering the heat. thanks for the replies! Can't wait to get started

 

I am using one of these http://www.austinhomebrew.com/Beer/...Temperature-Controller-Dial.html#.U3HItMejPgM The trick was getting a 110-120VAC outlet. I had an outlet rewired for such. Then I had to find a "Step up" to get it to 220-240VAC (found one for 3000p) and then I was able to use a standalone freezer for my fermentation unit. This setup has worked great so far (10 batches) and barely uses any electricity to maintain the temp at 70-72 or whatever temp desired.
