Description
XH-W1209 W1209 12V Red Digital Temperature Controller Module With Display and NTC Temp Sensor
The XH-W1209 12V Digital Temperature Controller is a compact, low-cost thermostat that combines a 3-digit red 7-segment display, a 3-key keypad, and a high-accuracy NTC10K temperature sensor. It lets you configure precise heating/cooling control in 0.1 °C steps and switches loads via an onboard relay.With the included waterproof NTC probe, the controller drives external devices based on the measured temperature. The screen shows the current temperature by default while an LED indicates the relay status. Front-panel parameters cover mode (heat/cool), hysteresis, upper/lower limits, offset, start delay, and a high-temperature alarm.

Customer Reviews
I'm so happy with this product.Intuitive installation!Great case. (That was unexpected) and so precise;If you are planing a project just buy this!It works perfectly!!!Congrats to this seller and the designer of this little device
Inexpensive, easy to use and generally pretty nice little controllers.
Great and user friendly relay
Easy to use
Although it registers in Celsius, easy to convert. takes its own power PLUS acts as a pass-thru relay. Very easy to use.
the temperature in Fahrenheit would have been better
Great item thanks and God Bless.
Worked great for RV anti freeze idea.
I use one of these to control the heat in a 3d printer enclosure. Works great!
It turns on the fans for the cabinet I keep my amp in. Nice little solution.
