Fortunately after many years of buying products from china I'm fluent in engrish. I installed these in my food truck to run the built in fridge. It has no problem switching the compressor on and off. One has the probe inside the cold box, the other has the probe taped to the compressor unit, controlling a fan to cool the compressor and evaporator. These were the last pieces I needed to get my fridge operating properly. They've been installed for 2 weeks and the fridge has maintained temp ever since. Review: Great value but consider thermal mass - These little things are amazing for the price, but I couldn't use them for my application because of the thermal mass of the sensor. I was measuring air temperature in a fan/heater system. The sensor lagged far behind the air temperature (about 1min) and overshot significantly, leading to big oscillations in temperature regulation. The sensor was reporting _its own_ temperature correctly, but the steel can around the thermistor was holding so much heat that the sensor wasn't the same temperature as the air. I could probably solve it by replacing the sensor with a fast-response 10k NTC thermistor, but I went with a different solution for now. ## Features - The instruction manual is in the last few pictures, if you need detailed electronic documents, please contact us - 2 Working modes: this digital LED temperature controller module has 2 working modes, heating mode (start temperature is lower than stop temperature) and cooling mode (start temperature is higher than stop temperature), range from -50°C to 120°C; The high temperature control accuracy reaches 0.1℃.Stable and reliable: the LED indicator light can display the current output status; The digital display tube can display the measured temperature, and the temperature measurement and control accuracy is high - Waterproof probe: equipped with a 1-meter NTC10K probe made of stainless steel, which is waterproof and not easy to rust, easy to use and can last for a long time - Durable material: this XH-W3230 digital thermostat switch is made of ABS, one of the five major synthetic resins, which is non-toxic, strong impact resistance, heat and low temperature resistance - Suitable for: the temperature controller module can be widely applied in the conditioning systems, incubators, equipment cases, temperature control protection and others - Control type: Button Control - Item shape: Rectangular ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B6HP396F | | Best Sellers Rank | #159,861 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #214 in Temperature Controllers | | Brand | Generic | | Brand Name | Generic | | Color | Black | | Customer Reviews | 3.8 out of 5 stars 27 Reviews | | Display Type | LED | | Included Components | red blue light | | Item Dimensions L x W x H | 3.11"L x 1.69"W x 1.02"H | | Manufacturer | Esedese | | Material | Stainless Steel | | Material Type | Stainless Steel | | Model | ASDS-ZH086 | | Part Number | ASDS-ZH086 | | Product Dimensions | 3.11"L x 1.69"W x 1.02"H | | Smart Home Compatibility | Not Smart Home Compatible | | Unit Count | 2.0 Count | | Voltage | 12 Volts | ## Product Details - **Brand:** Generic - **Color:** Black - **Display Type:** LED - **Material:** Stainless Steel - **Voltage:** 12 Volts ## Images ![W3230 Digital LED Temperature Controller Module Digital Thermostat Switch with Waterproof Probe Programmable Heating Cooling Electronic Thermostat Range from -50℃ to 120℃ (12V 10A 120W) (2 Pieces) - Image 1](https://m.media-amazon.com/images/I/51xzPlwVZ9L.jpg) ![W3230 Digital LED Temperature Controller Module Digital Thermostat Switch with Waterproof Probe Programmable Heating Cooling Electronic Thermostat Range from -50℃ to 120℃ (12V 10A 120W) (2 Pieces) - Image 2](https://m.media-amazon.com/images/I/51Hf8oWBQVL.jpg) ![W3230 Digital LED Temperature Controller Module Digital Thermostat Switch with Waterproof Probe Programmable Heating Cooling Electronic Thermostat Range from -50℃ to 120℃ (12V 10A 120W) (2 Pieces) - Image 3](https://m.media-amazon.com/images/I/61i0mjuBfwL.jpg) ![W3230 Digital LED Temperature Controller Module Digital Thermostat Switch with Waterproof Probe Programmable Heating Cooling Electronic Thermostat Range from -50℃ to 120℃ (12V 10A 120W) (2 Pieces) - Image 4](https://m.media-amazon.com/images/I/61wdwG86y2L.jpg) ![W3230 Digital LED Temperature Controller Module Digital Thermostat Switch with Waterproof Probe Programmable Heating Cooling Electronic Thermostat Range from -50℃ to 120℃ (12V 10A 120W) (2 Pieces) - Image 5](https://m.media-amazon.com/images/I/51IJQpMaGSL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Work Perfectly *by J***S on September 22, 2023* Other than the instructions written in Engrish, I've found these to work well.
