W1212 AC 220V LCD Digital Temperature Humidity Controller Thermostat Humidistat Timer SHT20 Sensor Probe for Incubator Aquarium Note: The product has a clock function with a battery. The product is shipped without a battery. The customer needs to buy the battery by himself. The battery model: CR1220 3V button. The battery needs to be calibrated for the first time. Time calibration operation mode: 1. In the case of power on, long pre the setting key to enter the setting interface, short pre the setting key to quickly switch (P/F/H), set the time to H, and select H1-H5 by the up and down keys. If you need real-time clock setting, select the corresponding H1 item, short pre the power button to enter the setting time, the up button is to increase, the down button is to decrease, and the power button is to confirm Instructions for setting operation: In the case of power on, long pre the setting button to enter the setting interface, short pre in the setting interface to quickly switch (P/F/H), you can use the up and down keys to select P1-P5/F1-F4/H1-H5, and then short pre The power button is OK to enter the setting parameters Specification: Product name: Intelligent temperature and humidity controller Product model: W1212 Power supply voltage: AC110 -220V Working frequency: 50HZ Measuring range: -40 -120C 0 -00%RH Measurement accuracy: temperature 0.3C, humidity 3%RH Sensor cable length: 100CM Size: 79.5*43*36mm Shell material: surface shell ABS, bottom shell flame retardant ABS Tips: In normal mode, short pre the setting key or plus and minus keys to view the setting parameters, it will return to normal mode after 1 second. In the setting mode, if no key is preed, it will automatically return to the normal working mode after 10 seconds. In the setting mode, when a certain option value is set, if the power button is not preed to confirm the return, it will automatically return to the normal working mode after 10 seconds, and the value will not be saved. Key Description: 1. Power button: Long pre the switch In the setting mode, short pre is the confirmation key 2. Setting key: Short pre to view the temperature control mode, short pre again to view the humidity control mode Long pre to enter the setting interface, short pre the setting button in the setting interface to select temperature control and humidity control or time mode (that is, P and F and H mode switching) 3. + key: On the homepage, short pre to view the target temperature switch time, long pre to turn on the target temperature switch time In the menu mode, short pre and 1 long pre and continue to add 4.-Key: Short pre to view the target humidity switch time on the homepage, long pre to turn on the target humidity switch time In the menu mode, short pre to decrease 1 and long pre to continue to decrease 5. Combination key: setting key + number minus (restore factory settings) In the power-on state, preing and holding the key combination at the same time will restore the factory settings Mode description: Both heating and cooling in temperature control mode and humidification and dehumidification in humidity control mode need to be set manually Temperature control mode: 1. Cooling mode: (You can short pre the setting button on the home page to view, or you can see the snowflake sign on the screen, that is, the current cooling mode) When the real-time temperature the target temperature setting value (OBJ TEMP) + the temperature difference setting value, it enters the cooling state, the relay works, and the cooling starts. When the real-time temperature drops to the target temperature setting value (OBJTEMP), the refrigeration relay stops working, the thermostat enters the temperature control state, and the temperature control range is the temperature difference setting value. When the real-time temperature the target temperature setting value (OBJ TEMP) + the temperature difference setting value, the thermostat enters the compreor delay state, and the refrigeration relay starts to work after the compreor delay. 2. Heating mode: (You can short pre the setting button on the home page to view, or the sun symbol can be seen on the screen, that is, the current heating mode) When the real-time temperature is le than the target temperature setting value-the temperature difference setting value, it enters the heating state and the heating relay works. 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 temperature difference set value. Humidity control mode: 1. Dehumidification mode: (You can short pre the setting button on the home page to view, or you can see the prohibition of water droplets on the screen, that is, the current dehumidification mode) When the real-time humidity and humidity temperature difference value (OBJ HUM) the target humidity value, the relay starts to work and starts dehumidification Whe
