This XH-W1219 12V Digital Red+Green Display Temperature Controller Module W/ NTC Waterproof Temperature Sensor. This Digital Display Temperature Controller Module designed as an affordable DC 12V Temperature controller. It comes with a waterproof NTC probe and integrated LED display in red and green. The module provides an NTC thermistor temperature sensing and has an accuracy of 0.1 C. The sensor can display the current temperature in degrees Centigrade via 3 digits seven-segment display and the current relay state by an on-board LED. This temperature controller can measure a temperature in the range of -50~+110 Degree Centigrade. Used to control temperature power in most types of electrical devices based on the temperature sensed by the NTC temperature sensor.
Moreover, the XH-W1219 thermostat module designed with its µC and I/O (sensor input, keys, double display, relay) can be re-programmed for automation tasks, and it’s easy to work with. An inbuilt embedded micro-controller makes programming quite simple. Hence, the various parameters in the module configured easily. This board is Nuvoton based controller
Button Functions :
- P0(Temperature Control Mode): When using this product for first time.Set H, if using it for heating, and set C, if using it for cooling.
- P1(Return Difference Setting): By Long pressing SET key enters into the internal setting, So choose P1 setting; then again press SET key to achieve return difference value setting
- P2(Temperature Calibration): This function for temperature calibration. If detection temperature and the actual temperature is different, then users use this function to calibrate
- P3(Delay Start): This is for compressor cooling
- P4(Set High-Temperature Alarm Value): When the actual temperature is greater than this value, the screen flashes and sound an alarm
