4. Setup u Wiring
Importanti: Tiżgura l-provvista tal-enerġija voltage matches the label on the product. Incorrect voltage can damage the module. Always disconnect power before wiring.
4.1 Dijagramma tal-Wiring
The W3230 controller has terminals for power input (+VCC, -GND), sensor input (S1, S2), and relay output (LOAD). Connect the power supply to +VCC and -GND. Connect the NTC sensor to S1 and S2. The load (heating or cooling device) should be connected to the relay output terminals, ensuring it is within the relay's specified current and voltage kapaċità.

5. Operazzjoni
5.1 Indikaturi tal-Wiri
- Output Indicator (OUT):
- Teptip: Indicates cooling or heating start-up delay is active.
- Dawl Kostanti: Indicates the relay is closed (output is active).
- Ebda Dawl: Indicates the relay is disconnected (output is inactive).
- PV Digital Tube (Red Display): Shows the actual measured temperature.
- SV Digital Tube (Blue Display): Shows the set temperature value (relay on/off threshold).
5.2 Issettjar tat-Temperatura
Biex tissettja t-temperatura mixtieqa:
- Press the "SET" button once. The SV digital tube (blue display) will flash.
- Use the "Up" (▲) and "Down" (▼) arrow buttons to adjust the temperature value.
- Press "SET" again to confirm the setting, or wait 8 seconds for automatic confirmation and return to normal display.
5.3 Main Menu Settings (P0-P8)
To access and configure advanced parameters:
- Long press the "SET" button for 3 seconds to enter the main menu. The display will show "P0".
- Press "SET" repeatedly to cycle through modes P0 to P8.
- When the desired mode (e.g., P0) is displayed, use the "Up" (▲) and "Down" (▼) arrow buttons to adjust its value.
- Long press "SET" for 3 seconds, or wait 8 seconds without any key action, to automatically confirm the setting and exit the menu.
5.4 Swiċċ tal-Enerġija
- Turn Off Display/Relay: Long press the "Restart" button for 1.5 seconds.
- Turn On Display/Relay: Press the "Restart" button again for 1.5 seconds.
