Specification:Product Name: Intelligent Temperature ControllerProduct Model: W1213 Power Supply Voltage: AC110 -220V Operating Frequency: 50HZ Temperature Range: -40 -120c Temperature Measurement Accuracy: 0.5c Sensor Cable Length: 100CM Size: 79.5*43*35mm Shell Material: ABS Surface Shell, ABS Fireproof Bottom CoverNote: The product has a clock function with battery. The product is delivered without batteries. The customer needs to buy the battery by himself. Battery model: CR1220 3V button battery. The battery needs to be calibrated for the first time. Time calibration working mode: when power on, long press the setting button to enter the setting interface, the up and down keys can select any P1-H2 menu. If you want to calibrate the time, use the up and down keys to select the P5 menu, short press the set key to confirm and enter, and then set the time with the up and down keys. Display panel descriptionHeat (corresponding icon display): heating mode, the heating relay operates in heating mode. Cool (corresponding icon display): cooling mode, the cooling relay is operating in cooling mode. Timer: Timing switch, in timer mode, icon flashOBJ LOW: set lower limit of target temperatureOBJ HIGH: upper target temperature settingHorizontal tent: increase. Going up means reducing the heat and going down means coolingKey description:1. Power button(1) In the power-on state, long press to turn off the power(2) In the power-off state, long press to turn on(3)In the setting mode, short press to confirm and press again to return to the home page to display the temperature.2. Set key(1) Long press to enter the setting mode option(2)In the setting mode option, short press to confirm the currently selected setting mode.3.-keyIn the setting mode interface, short press to subtract 1, long press to continue subtractIn the non-setting interface, long press to cancel the timing time.4.+ keyIn the setting mode interface, short press-times to increase by 1, long press, to continue increasing. In the interface without setting, short press to display the timer off time setting, long press the timer.5. Key combinationsSetting key + minus number (restore factory settings)In the power-on state, pressing the key combination at the same time will restore the factory settings (long press)Mode description:During normal operation, the LCD screen displays the measured value of the current temperature in real time, and automatically recognizes and switches the operation mode of cooling and heating.1. Cooling Mode:(1) When real-time temperature ge; the setting value of the upper limit of the target temperature, enters the cooling mode, the cooling indicator icon is on, the marquee decreases, and the cooling relay is working.(2) When the cooling temperature drops to the lower set value of the target temperature, the refrigeration relay stops working, and the thermostat enters the temperature control state, and the temperature control range is the upper and lower limit of the set value of the target temperature.(3)When the temperature rise value GE cooling; the setting value of the upper limit of the target temperature, the snowflake sign starts flashing, the thermostat enters the compressor delay state, and the refrigeration relay starts working after the compressor delay (the compressor delay time can be set)2. Heating Mode:(1) When the real-time temperature le; The lower limit value of the target temperature enters the heating state, the icon of the heat indicator is on, the marquee increases, and the heating relay works.(2) When the heating temperature reaches the setting value of the upper limit of the target temperature, the heating relay stops working, the tent stops, and the thermostat enters the temperature control state. The temperature control range is the upper and lower limits of the target temperature.3. Power On/Off Mode:(1) With the number plus key, set the power-on time-on time-on time, and in the timekeeping mode, you can turn off the time-off function by pressing the plus key(2) With the minus number key, set the power-on time in the power-on state and in the timekeeping mode, you can turn off the time-on function by long pressing the minus button. Tips:(1) In normal mode, short press the power button or plus button to display the setting parameters, it will return to normal mode after 1 second.(2)In setting mode, if no button is pressed, it will automatically return to normal working mode after 10 seconds.(3) In setting mode, when a certain option value is set, if the setting button or power button is not pressed, To confirm the return, the value will not be saved when it automatically returns to normal operation mode after 10 seconds. Package Included:1 * W1213 Thermometer with NTC Sensor Probe
