4.1. Control Panel and Display
The front panel includes an LCD screen and four control buttons: SET, MODE, Up (▲), and Down (▼).
Image 2: Detailed view of the controller's outlets and control buttons. OUT1 is for temperature, OUT2 for humidity, and OUT3 for timer functions.
- SET Button: Used to select an outlet for configuration or confirm settings.
- MODE Button: Used to change the operating mode (e.g., heating/cooling, humidification/dehumidification, timer program).
- Up (▲) Button: Increases values or navigates menu options.
- Down (▼) Button: Decreases values or navigates menu options.
- OUT1: Temperature controlled outlet.
- OUT2: Humidity controlled outlet.
- OUT3: Timer controlled outlet.
4.2. Probes
The controller comes with two separate probes: one for temperature and one for humidity. These probes are essential for accurate environmental monitoring.

5. Initial Setup
- Connect Probes: Plug the temperature probe and humidity probe into their respective ports on the controller. Ensure they are securely connected.
- Placement: Position the probes in the environment you wish to monitor and control. Ensure they are not directly exposed to heat sources, moisture, or airflow that could skew readings.
- Power On: Plug the controller into a standard 120V AC power outlet. The display will illuminate, showing current temperature, humidity, and time.
- Connect Devices: Plug your heating/cooling device into OUT1, your humidification/dehumidification device into OUT2, and any timed appliance (e.g., lights, misters) into OUT3.
6. Operating Instructions
6.1. Setting Temperature Control (OUT1)
- Press the SET button repeatedly until OUT1 is selected (indicated by a flashing OUT1 icon or similar).
- Use the Up (▲) or Down (▼) buttons to adjust the desired target temperature.
- Press MODE to cycle through heating (HEAT) or cooling (COOL) modes. Select the appropriate mode for your connected device.
- Press SET to confirm the temperature and mode.
- To set the temperature differential (hysteresis), press and hold SET for a few seconds when OUT1 is selected. Use Up/Down to adjust the difference between the set point and when the device turns on/off. Press SET to confirm.
6.2. Setting Humidity Control (OUT2)
- Press the SET button repeatedly until OUT2 is selected.
- Use the Up (▲) or Down (▼) buttons to adjust the desired target humidity percentage.
- Press MODE to cycle through humidification (HUMIDIFICATION) or dehumidification (DEHUMIDIFICATION) modes. Select the appropriate mode.
- Press SET to confirm the humidity and mode.
- To set the humidity differential, press and hold SET for a few seconds when OUT2 is selected. Use Up/Down to adjust. Press SET to confirm.
6.3. Setting Timer Control (OUT3)
- Press the SET button repeatedly until OUT3 is selected.
- Press MODE to enter the timer programming interface.
- Use Up (▲) or Down (▼) to set the ON time (hour and minute). Press SET to move to the next setting.
- Set the OFF time (hour and minute) using Up/Down and SET.
- The controller supports multiple ON/OFF programs for OUT3. Refer to the on-screen prompts for additional program slots.
- Press SET to save and exit the timer settings.
6.4. Switching Temperature Units (°C/°F)
To switch between Celsius and Fahrenheit, press and hold the Up (▲) button for approximately 3 seconds. The display will change accordingly.
7. Maintenance
- Cleaning: Wipe the controller unit with a soft, dry cloth. Do not use abrasive cleaners or immerse the unit in water.
- Probe Care: Keep the probes clean and free from debris. Avoid bending or damaging the probe cables. If probes become dirty, gently clean them with a damp cloth and allow them to dry completely before re-use.
- Storage: When not in use, store the controller in a cool, dry place away from direct sunlight and extreme temperatures.
8. Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| Display is blank or not powering on. | No power supply; loose connection. | Ensure the controller is securely plugged into a live power outlet. Check the power source. |
| OUT1/OUT2/OUT3 not activating connected device. | Incorrect settings; device malfunction; power issue. | Verify temperature/humidity/timer settings. Check if the connected device is working independently. Ensure the controller's set point is met for activation. |
| Humidity probe shows "ERR" reading. | Probe malfunction; damaged cable; sensor error. | Check the humidity probe connection. Inspect the probe cable for damage. If the error persists, the probe may need replacement. |
| Inaccurate temperature/humidity readings. | Probe placement; dirty probe; probe malfunction. | Relocate probes away from direct heat/moisture/airflow. Clean probes gently. If issues persist, consider probe replacement. |
