2. Configuració i instal·lació
Before installation, ensure the power supply is disconnected. This device requires careful wiring according to the chosen voltage (12V, 24V, or 110-220VAC).
2.1 Connexions de cablejat
The controller has terminals for power input (VCC, GND) and relay output for the load. Refer to the product's back label for correct wiring based on your power supply.

2.1.1 12V/24V DC Connection Method
For 12V or 24V DC power supplies, connect the positive terminal of your system power to the VCC terminal on the controller. Connect the negative terminal of your system power to the GND terminal. The load (heating or cooling device) should be connected to the relay output terminals, ensuring proper polarity if applicable to your load. Always consult the wiring diagram printed on the back of the device or in the full manufacturer's manual for precise connections.
2.1.2 110V/220V AC Connection Method
For 110V or 220V AC power supplies, connect the live wire (Firewire) and neutral wire (Null line) to the appropriate input terminals as indicated on the device or in the diagram below. The load is connected in series with the relay output. Exercise extreme caution when working with AC voltages.

2.2 Instal·lació del sensor
Connect the NTC10K waterproof sensor probe to the designated sensor input on the controller. Place the sensor in the environment where temperature measurement and control are required. Ensure the sensor cable is not damaged or exposed to excessive strain.
3. Instruccions de funcionament
The controller features a digital display and several buttons for easy operation.

3.1 Elements de visualització
- VA (Valor del Procés): Displays the actual measured temperature.
- SV (Valor definit): Displays the target temperature or setpoint.
- Indicador OUT: Illuminates when the relay output is active (heating or cooling is engaged).
3.2 botons de control
- Botó SET: Used to enter the setting mode for parameters.
- Botó amunt (▲): Increases values or navigates through menu options.
- Botó avall (▼): Decreases values or navigates through menu options.
- Botó de reinici: Resets the controller or confirms settings (functionality may vary, refer to specific model documentation if available).
3.3 Configuració de la temperatura
- Premeu el botó SET el botó una vegada. La pantalla SV començarà a parpellejar.
- Utilitza el Amunt (▲) i Avall (▼) botons per ajustar la temperatura objectiu desitjada.
- Premeu el botó SET button again to confirm the setting and exit the setting mode. The SV display will stop flashing.
3.4 Switching Between Heating and Cooling Modes
The controller automatically determines whether to operate in heating or cooling mode based on the set temperature and the actual temperature, along with internal hysteresis settings. For advanced parameter settings (e.g., hysteresis, calibration), consult the full manufacturer's manual if available. Typically, a long press of the SET button might access advanced settings.
4. Manteniment
To ensure the longevity and accurate performance of your Irfora Mini Temperature Controller 3230, follow these maintenance guidelines:
- Neteja: Netegeu suaument la pantalla iasing with a soft, dry cloth. Avoid using abrasive cleaners, solvents, or excessive moisture, which can damage the electronic components.
- Condicions ambientals: Operate the controller within the specified environmental requirements (-10-60℃, humidity 20%-75%RH) to prevent damage. Avoid direct sunlight, extreme temperatures, and high humidity.
- Cura del sensor: Ensure the sensor probe and its cable are free from damage. Do not bend the cable sharply or expose it to corrosive substances.
- Connexions: Reviseu periòdicament totes les connexions del cablejat per assegurar-vos que estiguin ben fixades i que no presentin corrosió.
5. Solució De Problemes
If you encounter issues with your temperature controller, consider the following common troubleshooting steps:
- Sense alimentació/Pantalla apagada:
- Check the power supply connection to the VCC and GND terminals.
- Verify that the power source (12V, 24V, or 110-220VAC) is active and providing the correct voltage.
- Inspeccioneu el cable d'alimentació per detectar qualsevol dany.
- Lectura de temperatura incorrecta:
- Ensure the NTC10K sensor probe is correctly connected to the controller.
- Check the sensor cable for any cuts, pinches, or damage.
- Verify the sensor is properly placed in the environment to be measured.
- If the reading is consistently off, the sensor might need calibration (refer to advanced settings if available) or replacement.
- Load Not Activating (Heating/Cooling Not Working):
- Check if the "OUT" indicator light is on when the load should be active.
- Verify the wiring connections to the load and the relay output terminals.
- Ensure the set temperature (SV) and actual temperature (PV) are configured correctly for the desired heating or cooling action.
- Test the load device independently to confirm it is functional.
- Display Flashing/Error Codes:
- If the display shows unusual characters or flashes, it might indicate a sensor error or a system fault. Disconnect power, wait a few seconds, and reconnect.
- Consult the manufacturer's specific error code documentation if available.
If these steps do not resolve the issue, contact the seller or manufacturer for further assistance.
