LCD thermostat manual

 

The temperature and humidity display, or the operation of the fan and automatic air vent will have some lag. Within 10-40 minutes, the work will start when stable Sunshine is detected. It is recommended to check again after half an hour. The program will run automatically. 

It is usually equipped with a 5V boost line, and the power adapter (5V, 1A or 2A) needs to be configured by the user. The power adapter (5V, 1A) applies to OS20/22/30/32; The power adapter (5V, 2A) applies to OS40/42.

Please use a strictly certified power adapter, otherwise the user will be responsible for any problems caused. The voltage of this thermostat is 12V and will not cause any safety problems.

 Operation

• During the operation, some icons or parameters will flash, indicating that they are being adjusted. If they are not operated within 10 seconds, the display will be on for a long time, indicating that they are in the state of the icon or parameter. If there is no operation for 10 minutes, the screen will turn off.
• The temperature and humidity display, or the operation of the fan and automatic air vent will have some lag. The program will run automatically.
• Pressing the SET button a third time displays the preset room temperature in this mode, which defaults to 26 ° C.
• After selecting one of the 5 modes, the corresponding mode will run after 10s.
• Solar energy is the priority, and electricity is used without solar energy. Please plug in the power when there is electricity, or the automatic vents may not close when the clouds suddenly block the sun. The power supply can reduce the operation times of the automatic air outlet and reduce the noise.
• To Fahrenheit users: Press the   key at the same time to switch between Celsius and Fahrenheit display. When setting the temperature, the unit is still Celsius; after setting, the temperature displayed on the screen will automatically switch. 5°C=41°F;10°C=50°F;15°C=59°F;20°C=68°F; 23°C=73.4°F;26°C=78.8°F; 28°C=82.4°F

• Time setting

  
  
  The correct clock must be set for the collector to work normally. To set the clock, press the SET and M buttons at the same time for more than 2 seconds.

  Wind speed adjustment in current mode: 

  1. Automatic mode in solar

  

  ： Ventilation start time, the default is 4 am;

  ： Switch to heating outdoor fresh air, default 12 o'clock at noon;

  ： Switch to continuous heating of indoor air, default 15 o'clock.

  2. Automatic mode in power use

  Part of the reason for not working:

   The operation of the fan or air vent will have lag. Within 10-40 minutes, the work will start when stable Sunshine is detected(cannot be interrupted). Insufficient sunlight, wrong lighting angle, and cloudy may interrupt the program. The fan can work only when the virtual load voltage(Not working voltage) is higher than 16V, 40min; or 18V, 20min.

   The correct clock must be set for the collector to work normally. To set the clock, press the SET and M buttons at the same time for more than 2 seconds.

   The human body can interfere with the analog signal. When testing the auto air vent or LCD thermostat, please do not hold them with your hands and connect the wire to auto air vent. Otherwise, it may not work.

   If there is a problem with the display and the function is not normal, it is likely that the wire is not plugged in tightly. Please unplug it and plug it in again.

   Avoid placing the photoelectric switch of the air vent directly at sunlight or incandescent lamps light.

   If the room temperature is higher than 24℃ (such as in summer), it may not work. Please set the temperature higher, such as 32℃, the device will start to work normally.

   Some power adapters may have unstable voltage, interruption or black screen in DC mode, etc. Please replace the power adapter.

   If you feel that the automatic air vent is noisy, please plug in the power to reduce the operations. Reduce the use of automatic mode.

   To obtain reasonable moisture, cold air may enter the room in the dry mode.

   The three--core wire connector must be inserted, otherwise the PV panel will display 0V. Use iron wire in series with red and yellow wires of three-core wire to test if the fan works.

   The warranty period is 2 years from the date of purchase.

  After disposal, please dispose of this product in an environmentally friendly manner:

  The device complies with the European ROHS guideline 2011 / 65 / EU on the use of certain hazardous substances in electrical and electronic equipment.
