Schematic diagram and manual:
Key Description:
1. Power button:
①Long press the switch
②In the setting mode, short press is the confirmation key
2. Setting key:
①Short press to view the temperature control mode, short press again to view the humidity control mode
②Long press to enter the setting interface, short press 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:
① On the homepage W-1212, short press to view the target temperature switch time, long press to turn on the target temperature switch time
②In the menu mode, short press and 1 long press and continue to add
4.-Key: ① Short press to view the target humidity switch time on the homepage, long press to turn on the target humidity switch time
②In the menu mode, short press to decrease 1 and long press to continue to decrease
5. Combination key: setting key + number minus (restore factory settings)
In the power-on state, pressing and holding the key combination at the same time will restore the factory settings
Tips
①In normal mode, short press the setting key or plus and minus keys to view the setting parameters, it will return to normal mode after 1 second. ②In the setting mode, if no key is pressed, it will automatically return to the normal working mode after 10 seconds. ③In 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 the normal working mode after 10 seconds, and the value will not be saved.
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 press 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)
①When 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.
②When 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.
③When the real-time temperature ≥ the target temperature setting value (OBJ TEMP) + the temperature difference setting value, the thermostat enters the compressor delay state, and the refrigeration relay starts to work after the compressor delay.
2. Heating mode: (You can short press 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)
① When the real-time temperature is less than the target temperature setting value-the temperature difference setting value, it enters the heating state and the heating relay works.
②When 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 press 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)
①When the real-time humidity and humidity temperature difference value (OBJ HUM) ≥ the target humidity value, the relay starts to work and starts dehumidification
②When the dehumidification humidity reaches the target humidity value, the dehumidification relay stops working and enters the humidity control state, and the humidity control range is the humidity setting value.
2. Humidification mode: (You can short press the setting button on the home page to view, or you can see the water drop mark on the screen, that is, the current humidification mode)
①When real-time humidity + humidity temperature difference value (OBJ HUM) ≤ target humidity value, the relay starts to work and starts to humidify.
②When the humidification humidity reaches the target humidity value, the humidification relay stops working and enters the humidity control state. The humidity control range is the humidity setting value.
Timming control :
Temperature timing switch operation instructions:
①The plus button controls the temperature timing, short press to view the timing to turn on or off the target temperature, long press the plus button to turn on the timing.
②In the home page W-1212, short press the plus button to display one one: one TEMP (for temperature timing shutdown) long press the plus button to turn off the target temperature, when the long press starts, XX:XX TEMP will be displayed
③In the home page interface, short press the plus button to display (for the temperature timing start) long press the plus button to start the target temperature regularly, when the long press starts, it will display XX:XX time
Humidity timer switch operation instructions:
①The minus button controls the humidity timing, short press to view the timing on or off the target humidity, long press the minus button to turn on the timing
②In the homepage interface, short press the minus button to display one one: one HUM (currently humidity timer shutdown), immediately press and hold the plus button to turn off the target temperature, when the long press starts, it will display XX:XX HUM
③In the homepage interface, short press the minus button to display –:– (currently the humidity is in the timing power on state) immediately press and hold the plus button to turn on the target temperature, and when the long press starts, XX:XX time will be displayed
