STC-1000 Temp Controller thread

[StoopheadFred]

Wanted to build a thread to collect info related to the STC-1000 digital temp controller.

For those not familiar this unit has become very popular among the home brewing crowd, as tight regulation of temperature can be key to brewing delicious beers. This controller has proven reliable in this application.

!!!!!ONE THING I REALLY WANT TO STRESS IS THAT THIS UNIT ONLY HAS 10AMP RELAYS!!!! From my understanding there are 2x 10amp fuses, one for the heating side and one for cooling. For people looking to run huge AC's and dehueys off this you may have to do some more work to use these safely.

If you google "stc-1000" there are tons of links about how to build this into a complete temp controller. I clicked through a few of them and found this one very clear and direct:

Now that you're familiar with the STC-1000, I would like to ask for some help designing this unit to work for our needs.

I’m looking to have 4 outlets total. 2 outlets for regular heating/cooling functions, and then 2 more outlets that will include a timer as well as heating/cooling functions.
Basically the timer on the heating side will be connected to a string of lights that will turn on and off as needed to regulate temperature, but the timer needs to be included to maintain the 12/12 light cycle. There will be another set of lights that are always on during the 12/12 cycle.
On the cooling side I’m still trying to figure things out. I’m wondering if it would be possible to integrate a 2-step speed controller for my 4” inline fan. So the fan circuit will be “always on” and regulated to ~60V, then when it reaches a set temp the circuit will activate the fan at full speed ~110V.

So… where my sparkys at?! Could really use some help on this one, and I think the community as a whole could benefit from having a nice temp controller like this

They could be used with 110/220 contactors, As long as the coil on the contactor matches the voltage of the STC-1000 Temperature Controller (110/220) this would allow you to trigger the on and off functions on any larger AC unit or even Dehumidifier.

I apologize for my previous post. The STC-1000 is actually only rated for 10A on the actual terminals. So actually I would simply use this as a Safety or Disconnect in case my temps went out of my desired range or incase my AC tripped the breaker and my lights were heating the room pasted the desired temp. Great unit for that aspect of your growroom updates.

Hope Ive been of some help.

I use one of those for my chiller. It works great, I used the internal 10a relay to switch the compressor relay on the unit.

Mine is 110v. I would simply use mechanical relays with 110v coils. You could use 24v coils as well but then you would need a power supply for that circuit.
I have a military surplus in town that has 30 dpdt relays that are new, real old mil spec stock and USA made! probably from the 60's. I pick them up for 5 bucks each!

Wow ...! its the same as mine but I call mine the Whilly temp controller, cheap ass made in Chine and does a great job, cooling, heating and germing all round the year ....lol

The STC-1000 digital temperature controller is an advanced temperature controller with sensor that permits you to keep your brewskie aging at the sought temperature by controlling both cooling and warming gadgets. The little unit will consequently switch in the middle of refrigerating and warming. The normal home brew situation is to have your lager maturing in an ice chest with the STC-1000 controlling the cooler temperature and in addition a hotness cushion or radiator cinch to keep your aging at a steady temperature.
