Specification:Product Name: Intelligent Temperature & Humidity Controller Product Model: W1212 Supply Voltage: AC110 -220V Working Frequency: 50HZ Measuring Range: -40 -120°c 0 -00% RHDmeasuring Accuracy: Temperature ± 0.3°C, Humidity ± 3%RH Sensor Cable Length: 100CM Measurement: 79.5*43*36mm Shell Material: ABS Surface Shell, ABS Flame Retardant Bottom CoverNote: The product has the function of a timer with battery. The product is delivered without batteries. The customer needs to buy the battery by himself. Battery model: CR1220 3V button. The battery must be calibrated for the first time. Time Calibration Working Mode:1. For power on, long press the setting key to enter the setting interface, short press the setting key to quickly switch (P/F/H), set the time to H, and select H1-H5 with the up and down keys. If you need to set the actual clock, select the corresponding item H1, short press the power button to enter the setting time, with binding, the button fastener is to increase, the down button is to decrease, and the power button is used to confirm the operation setting instructions:For power on, long press the setting button to enter the setting interface, short press in the setting interface, to switch quickly (P/F/H), you can use the up and down keys to select P1-P5/F1-F4/H1-H5, then short press the power button is ok to enter the setting parametersTips:(1) In normal mode, short press the setting key or plus and minus keys to display the setting parameters, it will return to normal mode after 1 second.(2)In the setting mode, if no key is pressed, it will automatically return to normal working mode after 10 seconds.(3)In the setting mode, when a certain option value is set, if the power button is not pressed to confirm the return, it will automatically return to normal working mode after 10 seconds, and the value will not be saved. Key Description:1. Power button:(1)Long press switch(2) In setting mode, short press is the confirmation key2. Setting key:(1) Short press to display the temperature control mode, short press again to display the humidity control mode(2) Long press to enter the setting interface, short press the setting key in the setting interface to select temperature control and humidity control or time mode (that is, P & F & H mode switching)3. + key:(1) On the home page, short press to display the target temperature switch time, long press to turn on the target temperature switch time(2) In menu mode, short press and 1 long press and further adding4.-key: (1) short press to display the target humidity switch time on the home page, long press to turn on the humidity switch target time(2) In menu mode, short press, to shrink 1 and long press to continue shrinking5. Combination key: setting key + minus number (restore factory settings)In the power-on state, pressing and holding the key combination at the same time will restore the factory settingsDescription mode:Both heating and cooling in the temperature control mode and humidification and dehumidification in the humidity control mode need to be set manuallyTemperature control mode:1. Cooling mode: (you can short press the setting button on the home page to view, or you can see a snowflake mark on the screen, which is the current cooling mode)(1) When the real-time temperature ge; target temperature setting (OBJ TEMP) + temperature difference set value, enters the cooling state, the relay works and cooling begins.(2) When the real-time temperature drops to the target value-temperature setting (OBJTEMP), the refrigeration relay stops working, the thermostat enters the temperature control state, and the temperature control range is the temperature difference.(3) When the real-time temperature ge; target temperature setting (OBJ temperature) + temperature difference setting value, the thermostat enters the compressor delay state, the refrigeration relay starts to work after the compressor is delayed.2. Heating mode: (you can short press the setting button on the home page to display, or the sun symbol can be seen on the screen, that is, the current heating mode)(1) When the real-time temperature is less than the target temperature setting-temperature difference setting value, it enters the heating state and the heating relay works.(2) When the heating temperature reaches the target temperature value, the heating relay stops working, The thermostat enters the temperature control state, and the temperature control range is the set temperature difference value. Humidity Control Mode:1. Dehumidification mode: (you can short press the setting button on the home page to display, or you can see the prohibition of water droplets on the screen, which is the current dehumidification mode)(1) When the real-time humidity and humidity temperature difference (OBJ HUM) ge; the target humidity value, the relay starts to work and starts dehumidifying(2)When the humidity of dehumidification reaches the target humidity value, the dehumidification relay s
