The W1209 Thermostat Temperature Control Switch is an incredibly low cost yet highly functional thermostat controller. With this module (HCTHER0006) you can intelligently control power to most types of electrical device based on the temperature sensed by the included high accuracy NTC temperature sensor. Although this module has an embedded microcontroller no programming knowledge is required. 3 tactile switches allow for configuring various parameters including on & off trigger temperatures. The on board relay can switch up to a maximum of 240V AC at 5A or 14V DC at 10A. The current temperature is displayed in degrees Centigrade via its 3 digit seven segment display and the current relay state by an on board LED.

*XH-W1219 Dual Display Digital Thermostat High Precision Temperature Control Switch
P0.Temperature Control Mode: when first use this product; if it is used to heating, please set H, if used to cooling, please set C
P1.Return Difference Setting: long press SET key entering into the internal setting, choose P1 setting; then press SET key to achieve return difference value setting
P2: Temperature Calibration: this function is for temperature calibration. If the detection temperature and the actual temperature is different, then users can apply this function to calibrate
P3: Delay Start: this function is for compressor cooling
P4: Set High-Temperature Alarm Value: when the actual temperature is higher than this value, the screen will flash and sound an alarm
