Packaging content: 1 thermostat Features: Product Name: Temperature and Humidity Controller. Product model: SHT2000. Power frequency: 50/60 Hz. Temperature range: -20~60 ° C. Humidity range: 0%~RH. Temperature measurement accuracy: 0.3. Humidity measurement accuracy: 3%. 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/dehumidifier mode). Set heating/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/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% relative humidity, and stop humidification at 80% 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% RH. Step 2: Press and hold the button for 3 seconds to stop flashing the humidity value. Set the value to 80% 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% relative humidity starts dehumidification, humidity 40% 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% RH. Step 2: Press and hold the button for 3 seconds to stop the humidity value flashing, set the value to 70% relative humidity, and after the setting is completed, the button will not work for 5 seconds and automatically return to the normal display state.
