STC-1000 10A DC 12V Digital LED Temperature Controller Cooling Heating Centigrade Thermostat 2 Relays LED Output with NTC Sensor Probe(12V)

Pretty straight forward to set up, my only complaint is that the wiring diagram is wrong, it should show the symbol for mains/AC power supply where it shows switches that are marked as 10A/220VAC as in the attached schematic. The video shows my unit in action controlling a 12 VDC heating cartridge that I want to maintain roughly around 60 C. (No cooling circuitry for now, but am considering finding a good peltier element to be able to tighten the temp range a little better than the current +/- 4 degC)

I got sucked in by the cheap price. It is made in China so the instructions are a poor translation. The instructions look like English words but they only make sense to the Chinese guy who thought he was composing English sentences. no one else will understand them. Most of the document is just gibberish. There is no troubleshooting menu or guidance. The setup instructions are ridiculous, but I figured it out. The thermister works and the display shows the temperature in Celsius. I am an American so I prefer Fahrenheit but that's no big deal...it's easy enough to convert. The set points for delay, difference, and the temperature activation point are easy to adjust. There is no wiring diagram so look at other products to figure out how to wire it to your device.

Works as described. The sensor is labeled as 'NTC' which strictly speaking means it's a negative temperature coefficient thermistor. For anyone trying to swap probes or fitting the probe in something I measured the following: Diameter: 4mm Resistances (in ohms) @ Temperature (degrees C): 16.0 kΩ @ 0 C, 5.52 kΩ @ 50 C, 1.40 kΩ @ 100 C Since neither are specified in the product specifications, don't be surprised if they change in the future.

I purchased this to control a 12 volt circulation fan in a dog room under the bed of my RV. I was going to do two fans, but decided to use the controller and loop the heat and cooling switch in series. It worked as planned. Although the average American doesn’t use Celsius so if your looking for something on the rather simple level this isn’t the controller you want. The quality and complicity of this controller is outstanding. Highly recommended for precise temperature control.

Using it to keep some electronic equipment from overheating. I have the 12 vdc model hooked to 2 muffin fans and the temperature senor mounted on the heat sink of the equipment. It is working perfectly. Works great, couldn't build one less expensive if I tried.

Yeah, Celsius is the worldwide favored temperature scale, but the biggest economy is STILL the USA which does everything in fahrenheit. This gauge doesn't allow fahrenheit readings.

really good little controller

Unusable it sways 20 degrees past the set point and cools back down constantly. No way i can use this , should have bought an inkbird lesson learned.

Using this to monitor temperature of network switches, and drive 12v cooling fans if a set point is exceeded. I have seen some possible issues with the 110/240v version of this product, but I have no concerns at 12v. The PCB could have been a little thicker, the casing could have been sturdier, but no complaints at this price point and low voltage use. The displayed temperature tracks well against reference thermometers, +/- 0.2c. You may also wish to consider the STC-3018 (I do not have this - but it appears to show both the environment and set points on the display).
