Temp controller thermostat for $10

[andybear]

I bought this thermostat off eBay for just under $10 and it works a treat. I've had it going for a week already with no problems yet. The centre reading is the actual temp and the left is the lower temp when it switches on and the right is the upper temp when it turns off. It also comes with the rtd temp probe on a one meter cord. A bit longer would have been better but none are on offer.
It takes 240 V as a power supply so no additional transformer is required. And I joined the supply to the output. The unit is small so I decided to just make a wooden box for it from some scrap bits I had lying around. The unit works by switching a relay that they claim can handle up to 10 amps. My heaters are 20 and 80 watts so that's less than half an amp combined.
I hope this helps someone who is thinking of getting a simple and cheap temp controller for their fermenter. :handgestures-thumbupleft:

Yep, http://www.ebay.com.au/itm/12V-220V-10A ... uiaxZNLUhw
be sure to select the voltage input to 240volt otherwise you'll need a 12v charger/supply.

Do you wire in the heater tube and the fridge into the device??? I have two fermentaion fridgees one I've had for around 5/6 years and it's controlled by an ATC 800 +. Never had any problems with it, but the unit only works on a +/- 1c.....sometimes this will rise well over 1.5 or 2 c.

I ordered a STC 1000 from Hong Kong a few weeks back for my 2nd fridge......wired it up and there's something that's not correct...the heater comes on....but the fridge will try to switch on as well.

I read on a beer forum a few years back were guys sent for the STC1000....only to have this promlem, but can't find it. I'm still playing with it but now I've seen the one you have I may send for one. They post to the UK...do you have a wiring dia that you used?? just so I can get my head around it.. :smile:

Looking at the back of that it only does heating OR cooling. Not both so good for heatin in cool climes or cooling in hot ones.
I like the stc and have two of them because it can do both heating and cooling if you need it to.
Ice fever- can you show how you've wired it up? Maybe a photo in another topic so this isn't cluttered? Are you confident you've got it wired up the right way? I stuffed mine the first time by wiring in the neutrals into the switches.

I had a look at your STC controller. It should turn your heating and cooling on and off as needed. Look at this http://www.ebay.com.au/itm/220-240V-Dig ... xyni9TGSEn for the connection diagram you need to use.
My controller will only do one output so only heating or cooling.
The connection diagram I followed is attached. I hope.

@ Warramungas...I thought this, just works on one unit....we're away this weekend but when we get back home I'll post a new thread with a photo or two.

@ Andybear....I've followed the dia that they send with the unit...but as I posted some units came wired wrong....if I remember right the two circuits were crossed over....and the other guys just switched the heater and fridge over and it worked ok.

Have you got some wires crossed. you mentioned the heater and fridge coming on simultaneously. I wired one up myself a while back and it works flawlessly.

I also have one in my salami fridge it,s been running few years
It turns on to cool and if it overshoots depending on the setting the heater comes on
Just about to order some more for controlling the hot house
