4. Konfigurazioa eta kableatzea
Proper wiring is crucial for the safe and effective operation of the temperature controller. Ensure all connections are secure and correct before applying power.
4.1 Kableatu-diagrama
The controller requires a 12V DC power input. The load (e.g., heating element, cooling fan) is connected via the relay terminals. There are two primary wiring methods depending on whether the load shares the same 12V power source as the controller or uses a separate power source.
Image: Wiring diagrams for the temperature controller.
Method 1: Temperature Control and Load with Shared 12V Power
- Connect the 12V DC positive (+) and negative (-) power supply to the controller's input terminals.
- Connect the load's positive terminal to the controller's relay output (NO or NC, depending on desired operation).
- Connect the load's negative terminal directly to the 12V DC negative (-) power supply.
Method 2: Temperature Control and Load with Different Power Sources
- Connect the 12V DC positive (+) and negative (-) power supply to the controller's input terminals.
- Connect the load's power source (e.g., a separate 12V or 24V supply) to the relay terminals. The controller acts as a switch for this separate power circuit.
- Ensure the load's power source is compatible with the relay's specifications (10A/250VAC, 7A/250VAC).
Note: Always ensure the power supply voltage matches the controller's requirements (12V DC). Incorrect voltagGailua kaltetu dezake.
5. Funtzionamendu-argibideak
The controller features a simple interface for setting the desired temperature and operating mode.
5.1 Tenperaturaren ezarpena
- Sakatu EZARTU button. The LED display for the set temperature will flash.
- Erabili C (+) eta F (-) buttons to adjust the set temperature value.
- After setting the desired temperature, wait for approximately 3 seconds. The module will automatically save the parameters and exit the setting mode.
5.2 Switching Between Celsius and Fahrenheit
To switch the temperature display unit between Celsius (°C) and Fahrenheit (°F), press and hold the C / F button for a few seconds until the display changes.
5.3 Operating Modes (Heating/Cooling)
The controller can operate in either heating or cooling mode. The specific method to switch between these modes typically involves setting the hysteresis (backlash precision) and the set point relative to the current temperature. Consult the detailed programming instructions that may be available online by searching for similar models like "Ketotek KTF0091" if specific instructions were not included with your product.

6. Mantentzea
To ensure the longevity and accurate performance of your temperature controller, follow these maintenance guidelines:
- Garbiketa: Gently wipe the display and module casinGarbitu zapi leun eta lehor batekin. Saihestu garbitzaile edo disolbatzaile urratzaileak erabiltzea.
- Sentsoreen zainketa: While the NTC sensor is waterproof, avoid unnecessary physical stress or bending of the probe cable. Ensure the sensor is clean and free from debris for accurate readings.
- Ingurumen-baldintzak: Operate the controller within its specified temperature and humidity ranges. Avoid exposure to extreme conditions or direct sunlight for prolonged periods.
7. Arazoak
Tenperatura-kontrolagailuarekin arazoak badituzu, jo ezazu honako arazo eta irtenbide ohikoenei:
7.1 Display Shows "LLL"
- Arazoa: The display shows "LLL" instead of a temperature reading.
- Irtenbidea: This typically indicates a problem with the temperature sensor. Check if the NTC sensor is properly connected to the module. Inspect the sensor cable for any damage or breaks. If the sensor is damaged, it may need replacement.
7.2 Controller Resets Repeatedly or Malfunctions Under Load
- Arazoa: The controller resets or turns off when a load is connected or activated, especially with higher amparo kargak.
- Irtenbidea: This can occur if the load exceeds the controller's internal relay capacity or if there are power supply issues.
- Egiaztatu elikadura iturria: Ensure your 12V DC power supply is stable and can provide sufficient current for both the controller and the load. A weak or unstable power supply can cause resets.
- Karga-gaitasuna: Verify that the connected load's current draw does not exceed the relay's maximum rating (10A/250VAC, 7A/250VAC). For loads close to or exceeding this limit, consider using an external relay or MOSFET to switch the high-current load, with the temperature controller activating the external switching device.
- Kableatua: Double-check all wiring connections for looseness or short circuits.
7.3 Difficulty Programming or Setting Parameters
- Arazoa: Unable to enter programming mode or save settings.
- Irtenbidea: Ziurtatu sakatuta eta eutsita duzula EZARTU button for the correct duration to enter programming mode. If the controller exits programming mode too quickly, try to adjust the parameters more swiftly. Some models may have a timeout feature. If specific programming steps are unclear, search online for manuals related to similar 12V programmable thermostats (e.g., "W1209 thermostat manual" or "Ketotek KTF0091 manual") as these devices often share similar interfaces and programming logic.
