6. Setup and Installation

6.1. Initial Setup

1. Unpack: Carefully remove the controller and all accessories from the packaging.
2. Inspect: Check the device and sensor probe for any visible damage. Do not use if damaged.
3. Connect Sensor: Plug the temperature sensor (for DTC101) or humidity sensor (for DHC101) firmly into the designated sensor input port on the top right of the controller.
4. Placement: Place the controller in a stable location, away from direct heat sources or excessive moisture. The integrated hook allows for wall mounting.
5. Position Sensor: Position the sensor probe in the environment where temperature or humidity needs to be controlled. Ensure it is not obstructed and can accurately read the ambient conditions.

6.2. Power Connection

1. Ensure the controller's output sockets are not connected to any devices yet.
2. Plug the controller's power cord into a standard electrical outlet (100-240V AC, 50/60Hz). The display will illuminate.
3. Once the controller is powered on, the display will show the current measured temperature (DTC101) or humidity (DHC101).

6.3. Connecting Appliances

1. For DTC101: Plug your heating device into one output socket and your cooling device into the other. Ensure the devices are compatible with the controller's maximum load (e.g., 10A/1200W).
2. For DHC101: Plug your humidifying device into one output socket and your dehumidifying device into the other. Ensure compatibility with the controller's maximum load.
3. The controller will automatically switch power to these sockets based on your set parameters.

7. Operating Instructions

7.1. Setting Temperature (DTC101)

1. View Current Settings: Press the SET button once briefly. The display will show the current Set Value (SV) for temperature.
2. Enter Setting Mode: Press and hold the SET button for approximately 3 seconds until the SV value starts flashing.
3. Adjust Set Value: Use the Up or Down arrow buttons to adjust the desired temperature set point.
4. Confirm Setting: Press the SET button again to confirm and save the new set point. The display will return to showing the current temperature.
5. Temperature Calibration (Optional): If calibration is needed, consult the full manual for advanced settings.

7.2. Setting Humidity (DHC101)

1. View Current Settings: Press the SET button once briefly. The display will show the current Set Value (SV) for humidity.
2. Enter Setting Mode: Press and hold the SET button for approximately 3 seconds until the SV value starts flashing.
3. Adjust Set Value: Use the Up or Down arrow buttons to adjust the desired humidity set point.
4. Confirm Setting: Press the SET button again to confirm and save the new set point. The display will return to showing the current humidity.
5. Humidity Calibration (Optional): If calibration is needed, consult the full manual for advanced settings.

7.3. Operating Modes (DTC101 & DHC101)

The controllers automatically switch between heating/cooling or humidifying/dehumidifying modes based on the set point and the measured value. For example, if the measured temperature is below the set point, the DTC101 will activate the heating output.
