Aideepen STC-1000 Temperature Controller, DC 12V 10A All-purpose Digital Thermostat with NTC Sensor Probe for Fermentation Hatch Freezer Heating and Cooling

Bought 2 or 3 years ago, difficult to understand wiring instructions but there are several videos on You Tube which help 👍🏻 Has worked faultlessly controlling heaters and cooling fans 😉

I liked the fact this unit does exactly what it states, for a very reasonable price. I didn't like the documentation - the Url in the accompanying printed sheet gave "404 not found". No other documentation in the sheet. After some internet searches: F1 = your target temperature (-50C to 99C) F2 = your temperature tolerance around F1 (plus or minus 1C to 10C) F3 = Compressor Delay Time. I'm not sure what this does. F4 = temperature calibration adjustment (-10C to 10C). Maybe the temp sensor isn't 100% accurate. So if you want 21C with a 3C band around that: F1 = 21C F2 = 3C The heating relay will switch on when temp <= (21-3) The cooling relay will switch on when temp >= (21+3) In between (21-3) and (21+3) this unit does nothing, other than report the temperature. 21 and 3 are my example figures. It works fine if nothing connected to heating or cooling (or both). Use your left thumb for pressing the small "S" (Set) button. You'll need your right thumb for pressing the up and down arrows for adjusting, while holding down the S button. Here's a link another seller provided to some pdf documentation: https://images-na.ssl-images-amazon.com/images/I/71VSFdFfszL.pdf The wiring diagram in the above pdf shows ground as in/out of the heating/cooling relays. I used positive (12V) and it worked fine. The terminals (5+6) and (7+8) do NOT provide + and - They provide a "make/break" switch on a single wire. Whether that wire carries + or - is up to you. I'm using this to temperature control some astronomy equipment in the cold months. I bought some "12V heater film strips" from "sourcing map" here on Amazon and they work very well. In the warm months I'll connect a fan to the cooler relay to cool things down. I replaced the temperature sensor with a different 10K NTC probe (also from Sourcing Map). It is of the waterproof type with a much smaller "bead head", which fits into the small space I need. All in all - this ST 1000 is very flexible, great value for money, and once you understand how it works it's very simple to integrate into almost any scenario.

A decent low cost temperature controller. I extended the temperature sensor wires by a few feet and it all still works. My controller has been set up in a damp environment for 2 years now and still performs well.

As described.

Used to control a small extractor fan to exhaust warm air from a battery & inverter cupboard on my motorhome.

Arrived, but does not work, it won't turn on.

It works fine, however I wanted it to work on 12 v dc throughout my system. It works fine on 12 v dc on input and probe side however on the wiring diagrams it shows the heating cooling as 220 v ac . I have a 12 v dc prettier cooler so as stated it's all 12 v dc . There are no diagrams for 12 v dc yet it is a 12 v dc unit. Eventually sorted it out and put a link from live to cooling on the positive side. On the prettier cooler put the positive side to the unit cooler switch and put the common side of cooler jointly into the common input side. Once this was worked out the unit works great.

I bought the 12V version to control a fan in my motorhome. The first controller I bought made a high pitched noise. However, I bought a second one which was fine (I’ve returned the first one - Amazon make it so easy). This one works perfectly. The temperature probe is only 1m long but it is very easy to extend it. This is amazing value for money. Recommended.

Perfetto, a me è servito per gestire la temperatura del mio acquario, impostata la soglia di funzionamento si attivano le ventole di raffreddamento, raggiunta la soglia ok si spengono le ventole, il tutto è possibile perché c'è una sonda che messa in acquario rileva la temperatura

We live in a big farm that we are turning in a zero emission hotel kind of place. We started off with resol, valliant etc systems. And they are not bad, but after over 10 years, non was without an outage. We have at least a dozen of these industrial cheap Chinese temperature relais, and never did even 1 fail. Never even had to replace the sensor. These things are dumb relais. But dumb relais that keep on going.

Nu känner mina fläktar av när dom ska starta för att hålla bra temperatur till kylskåpet som finns i min husbil

Très bon produit, mais il faut installer un relais 12 volt 40 amp sinon a la longue l'appareil peut être hors service car il n'accepte que 10 amp. Un petit investissement de 7 € environ et quelques câblage rallongera la durée votre installation.
