2. Setup Instructions
2.1 Unpacking and Inspection
Carefully remove the controller from its packaging. Inspect the device and its sensor for any signs of damage. Ensure all components listed in the package contents are present.
2.2 Connecting the Device
- Plug the KETOTEK controller directly into a standard power outlet.
- The external sensor is already connected to the main unit. Ensure the sensor cable is not damaged.
- Place the sensor in the environment where humidity and temperature need to be monitored and controlled. Ensure it is not directly exposed to water or extreme conditions that could damage it.
- Plug your humidifier, dehumidifier, heater, or cooler into the outlet on the front of the KETOTEK controller.

2.3 Initial Power On
Once plugged in, the display will light up, showing the current measured humidity and temperature. The device is now ready for configuration.
3. Operating Instructions
The controller features a clear digital display and four buttons: MODE, SET, UP/CLK, and DOWN. These buttons are used to navigate menus and adjust settings.

3.1 Understanding Operating Modes
The controller supports four primary operating modes:
- Humidification Mode (HC mode): Activates the connected device when humidity drops below the set start humidity.
- Dehumidification Mode (HC mode): Activates the connected device when humidity rises above the set stop humidity.
- Heating Mode (TC mode): Activates the connected device when temperature drops below the set start temperature.
- Cooling Mode (TC mode): Activates the connected device when temperature rises above the set stop temperature.

3.2 Setting Humidity Control Parameters
- Press the MODE button to cycle through the modes until "HC mode" is displayed.
- Press and hold the SET button for 3 seconds to enter the setting menu.
- Use UP/CLK or DOWN buttons to adjust the "Start Humidity" value. This is the humidity level at which the connected device will turn ON (for humidification) or OFF (for dehumidification).
- Press SET again to move to "Stop Humidity". Adjust this value using UP/CLK or DOWN. This is the humidity level at which the connected device will turn OFF (for humidification) or ON (for dehumidification).
- Press and hold SET for 3 seconds to save settings and exit.

3.3 Setting Temperature Control Parameters
- Press the MODE button to cycle through the modes until "TC mode" is displayed.
- Press and hold the SET button for 3 seconds to enter the setting menu.
- Use UP/CLK or DOWN buttons to adjust the "Start Temperature" value. This is the temperature at which the connected device will turn ON (for heating) or OFF (for cooling).
- Press SET again to move to "Stop Temperature". Adjust this value using UP/CLK or DOWN. This is the temperature level at which the connected device will turn OFF (for heating) or ON (for cooling).
- Press and hold SET for 3 seconds to save settings and exit.

3.4 Setting Alarm Functions
The controller can alert you when humidity or temperature exceeds or falls below set thresholds.
3.4.1 Humidity Alarm (HC Alarm)
- Press the MODE button until "HC Alarm" is displayed.
- Press and hold the SET button for 3 seconds.
- Use UP/CLK or DOWN to set the desired humidity alarm threshold.
- Press and hold SET for 3 seconds to save and exit.

3.4.2 Temperature Alarm (TC Alarm)
- Press the MODE button until "TC Alarm" is displayed.
- Press and hold the SET button for 3 seconds.
- Use UP/CLK or DOWN to set the desired temperature alarm threshold.
- Press and hold SET for 3 seconds to save and exit.

3.5 Calibration
To calibrate the humidity or temperature readings:
- Press and hold the UP/CLK and MODE buttons simultaneously for 3 seconds to enter calibration mode.
- Use UP/CLK or DOWN to adjust the humidity calibration value (range: -10% to +10% RH).
- Press SET to switch to temperature calibration. Adjust the temperature calibration value (range: -9.9°C to +9.9°C) using UP/CLK or DOWN.
- Press and hold the MODE button for 3 seconds to save the calibration and exit.
3.6 Reset Function
To reset the controller to factory default settings:
- Locate the reset button (small hole) on the side of the device.
- Use a thin, pointed object (like a paperclip) to press and hold the reset button for 3 seconds.
- The device will restart, and all settings will revert to their default values.

3.7 Temperature Unit Switching (°C/°F)
To switch between Celsius and Fahrenheit:
- While in normal operating mode, press the UP/CLK button briefly. The temperature unit on the display will toggle between °C and °F.
3.8 Button Sound Settings
To enable or disable the button press sound:
- While in normal operating mode, press and hold the DOWN button for 3 seconds. The button sound will toggle ON/OFF.

4. Maintenance
4.1 Cleaning the Sensor
To ensure accurate readings, periodically clean the sensor probe. Gently wipe the sensor with a soft, dry cloth. Avoid using abrasive cleaners or submerging the sensor in liquids, as this can damage the sensitive components.
4.2 General Care
- Keep the controller and sensor away from direct sunlight, high humidity (unless intended for the sensor), and extreme temperatures.
- Ensure the device is unplugged before cleaning or performing any maintenance.
- Do not attempt to open or repair the device yourself, as this will void the warranty and may cause electric shock.
5. Troubleshooting
This section addresses common issues you might encounter with your KETOTEK Digital Humidity and Temperature Controller.
| Problem | Possible Cause | Solution |
|---|---|---|
| "E1" or "E2" displayed | Sensor disconnected or short-circuited. | Check the sensor connection. Ensure it is securely plugged into the controller. If the error persists, the sensor may be faulty and require replacement. |
| "HHH" or "LLL" displayed | Measured humidity/temperature is outside the measurable range. | Ensure the environment's conditions are within the controller's operating range (Humidity: 20-95% RH, Temperature: -10°C to 50°C). If the environment is within range, the sensor might be faulty. |
| Connected device not turning ON/OFF | Incorrect settings, device malfunction, or power issue. | Verify your "Start" and "Stop" humidity/temperature settings. Ensure the connected device is functioning correctly by plugging it directly into a wall outlet. Check if the controller is receiving power. |
| Inaccurate readings | Sensor dirty, calibration needed, or sensor malfunction. | Clean the sensor as described in the Maintenance section. Perform a calibration as described in section 3.5. If readings remain inaccurate, the sensor may need replacement. |
| Alarm sounds continuously | Environment conditions are outside the set alarm thresholds. | Check the current humidity/temperature and compare it to your alarm settings. Adjust the environment or the alarm thresholds if necessary. |
