Packaging content: 1 thermostat Features: Product Name: Temperature and Humidity Controller. Product model: SHT2000. Power frequency: 50 or 60 Hz. Temperature range: -20-60 C. Humidity range: 0 percent -RH. Temperature measurement accuracy: 0.3. Humidity measurement accuracy: 3 percent . Output control: Relay output. Output power: maximum 10 A. Setting method: Initial value. Setting method: Start value>Stop value (the program automatically determines the operating mode as cooling or dehumidifier mode). Set heating or cooling mode: Setting mode (start temperature): Press and hold the button to start flashing temperature. Use the button to set the starting temperature value. Setting (temperature stop): Press and hold the button to stop the temperature flashing. Use to set the stop temperature value. Heating usage: Control the water heater, stop heating at 65 C, drop the temperature to 50 C, and start heating again Step 1: Heating mode, start temperature. Step 2: Press and hold the button to start flashing temperature. Use to set the startup temperature to 50 C. Step 3: Press and hold the button to stop the temperature flashing. Use the button to set the stop temperature to 65 C, and the setting is complete. Refrigeration use case: For farm use, the fan stops ventilation at 26 degrees Celsius, rises to 30 degrees Celsius, and starts ventilation again. Step 1: Cooling mode, start temperature>stop temperature Step 2: Press and hold the button to start flashing temperature. Use to set the startup temperature to 30 C. Step 3: Press and hold the button to stop the temperature flashing. Use to set the stop temperature to 26 C. Adjustment completed. Humidification or dehumidification mode settings: Set (start humidity): Press and hold the humidity value key to activate the flashing humidity value. Set the humidity value by pressing the button. Set [Stop Humidity]: Press and hold the humidity value key to stop the humidity value, and set the humidity to stop at Example of humidification: Supermarket fresh humidification, control the humidifier to start humidification at 50 percent relative humidity, and stop humidification at 80 percent relative humidity. Installation steps: Step 1: Press and hold the " button for 3 seconds to start flashing the humidity value, and set the initial humidity value to 50 percent RH. Step 2: Press and hold the button for 3 seconds to stop flashing the humidity value. Set the value to 80 percent relative humidity. Once the setting is completed, the button will not work for 5 seconds and automatically return to the normal display state. Dehumidification example: Exhaust dehumidification system, humidity 70 percent relative humidity starts dehumidification, humidity 40 percent relative humidity stops dehumidification Installation steps: Step 1: Press and hold the " button for 3 seconds to start flashing the humidity value, and set the initial humidity value to 40 percent RH. Step 2: Press and hold the button for 3 seconds to stop the humidity value flashing, set the value to 70 percent relative humidity, and after the setting is completed, the button will not work for 5 seconds and automatically return to the normal display state.
