Powered by a 12V DC supply and equipped with an NTC sensor, it offers reliable, real-time temperature control and display, making it ideal for both industrial and home automation applications. ## Description NTC temperature sensor allows the module to intelligently control varied electrical devices based on the temperature. NTC thermistor has a negative temperature coefficient, which means the resistance decreases with increasing temperature. The relay can operate at voltages up to a maximum of 240V AC at 5A or 14V DC at 10A to power on. The temperature is displayed in degree centigrade and with the help of 7-segment display and the relay, the state is displayed with the help of the LED present on the W1209 module. Indicator: off indicates the relay is switched off; always indicates the relay is closed. LED: shows ll means the sensor opens; shows hh means it s out of range, the thermostat will be forced to close the relay, the display as high temperature protection. Temperature range: 50~110 and deg; c resolution: 0. 1 And deg; c(9. 9~99. 9 And deg; c), 1 and deg; c(other ranges) accuracy: 0. 1 And deg; c refresh rate: 0. 5S high temperature protection: 0~110 and deg; c input power: DC 12v static current: and le; 35ma, attract current: and le; 65ma measurement input: ntc(10k 0. 5 Percent) waterproof type sensor output range: 1 channel 10a relay output environment: 10~60 and deg; c? Humidity: 20 percent 85 percent model: wh w1209 size: approx. 48X40x15mm specification: how to use: connect the power supply and the load, then you can supply to the controller. It displays the measured temperature, press set key, the display temperature flashing, press plus to set the desired temperature. After finished, press set to confirm and back. Now the controller automatically performs the relay by setting off. This temperature controller output is 10a relay, meeting various high power loads, please make sure the wires are connected correctly. Package includes: 1x digital temperature control. Review: Good - Super super Review: So with this trick you can easily calibrate it.. - Its great product. It has got all the capacitor and resistor expect c1. Which is not given in thermostats these days. But it is working realy somooth and stable. You can calibrate it with these steps. Put ice un a class of water pour half water. Qnd put you sensor in the right middle without touching the class. Wait 2 minutes atleast. Now according to the reading it should be showing 0 degree. And a bit forward and backward. In my case it was 0.4. so i long pressed and set my p4 to -0.3 now its showing 0.1. its perfectly calibrated. ## Features - W1209 thermostat module has a temperature sensor, keys, LED display, relay and requires DC 12V power supply. - W1209 has an inbuilt embedded micro-controller, thus not much programming knowledge is required. - The module consists of three switches to configure the various parameters including ON and OFF trigger temperatures. - The W1209 digital temperature controller or the thermostat is in perfect working condition and comes in great pakaging. - Package Includes: 1 x W1209 Digital Temperature Controller Thermostat Module. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08JM4SSKQ | | Backlight | Yes | | Best Sellers Rank | #30,208 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #175 in Temperature Controllers | | Brand | Robocraze | | Colour | Green | | Connectivity Protocol | Wired | | Connectivity Technology | Wired | | Control Method | Touch | | Control Type | Button Control | | Controller Type | Push Button | | Country of Origin | China | | Customer Reviews | 4.2 out of 5 stars 27 Reviews | | Display Type | led | | Item Type Name | W1209 | | Item Weight | 75 Grams | | Manufacturer | 9th Main, 1st C Cross, HRBR Layout, Banaswadi, Bengaluru, Karnataka 560043, 080 4851 1516, Robocraze | | Manufacturer Contact Information | 9th Main, 1st C Cross, HRBR Layout, Banaswadi, Bengaluru, Karnataka 560043, 080 4851 1516 | | Model Name | VA-EW58-TIYX | | Model number | VA-EW58-TIYX | | Mounting Type | Wall Mount | | Packer Contact Information | Robocraze 9100088099 | | Power Source | Battery Powered | | Product Features | Digital Display | | Product Style | Digital | | Special Feature | Digital Display | | Temperature Control Type | Digital | | Unit Count | 1 Count | | Voltage | 12 Volts | ## Product Details - **Brand:** Robocraze - **Colour:** Green - **Connectivity Technology:** Wired - **Controller Type:** Push Button - **Item Weight:** 75 Grams - **Model Name:** VA-EW58-TIYX - **Power Source:** Battery Powered - **Special Feature:** Digital Display - **Temperature Control Type:** Digital - **Voltage:** 12 Volts ## Images ![W1209 Digital Thermostat Controller | 50~100 Digital Temperature Controller Thermostat | High Precision Digital Temperature Controller- (Pack of 1) - Image 1](https://m.media-amazon.com/images/I/51G1m6zOeKS.jpg) ![W1209 Digital Thermostat Controller | 50~100 Digital Temperature Controller Thermostat | High Precision Digital Temperature Controller- (Pack of 1) - Image 2](https://m.media-amazon.com/images/I/61yjjLNUjNS.jpg) ![W1209 Digital Thermostat Controller | 50~100 Digital Temperature Controller Thermostat | High Precision Digital Temperature Controller- (Pack of 1) - Image 3](https://m.media-amazon.com/images/I/511E6grsLeS.jpg) ![W1209 Digital Thermostat Controller | 50~100 Digital Temperature Controller Thermostat | High Precision Digital Temperature Controller- (Pack of 1) - Image 4](https://m.media-amazon.com/images/I/518Q7xDkYgS.jpg) ![W1209 Digital Thermostat Controller | 50~100 Digital Temperature Controller Thermostat | High Precision Digital Temperature Controller- (Pack of 1) - Image 5](https://m.media-amazon.com/images/I/61+ltKqkxpL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good *by A***D on 12 October 2020* Super super ### ⭐⭐⭐⭐ So with this trick you can easily calibrate it.. *by V***E on 29 December 2021* Its great product.
