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.
