Coliao W3230 Digital Temperature Controller User Manual

Introducción

The Coliao W3230 Digital LED Temperature Controller Module is a high-precision device designed for temperature control in various applications. It features a clear digital LED display for enhanced readability and offers both heating and cooling control modes. This module is equipped with a waterproof NTC10K probe for accurate temperature measurement.

Key features include a wide temperature measuring range of -50℃ to 120℃, high control precision of 0.1℃, and the ability to save all parameter settings after a short circuit. It utilizes a relay output for control and is suitable for use in domestic freezers, water tanks, refrigerators, industrial chillers, steamers, and other temperature-controlled systems.

Configuración y cableado

Before connecting the W3230 temperature controller, ensure the power supply is disconnected. The module supports DC 12V, DC 24V, or AC 110V~220V power inputs. The NTC10K waterproof sensor has a 1-meter wire. The relay output has a contact capacity of 10A 220V / 20A 12V / 20A 24V.

Refer to the wiring diagram below for proper connection. Connect the power supply to the +VCC and -GND terminals. The load (heating or cooling device) should be connected to the S1 and S2 relay output terminals.

Importante: Ensure the working power supply voltage matches the label on the product.

Instrucciones de funcionamiento

The W3230 controller features a clear LED display with two digital tubes: PV (red) and SV (blue). The PV digital tube displays the actual measured temperature, while the SV digital tube displays the set temperature value for relay activation.

Estado del indicador

• Brillante: Indicates cooling or heating start-up delay.
• Luz constante: Indicates the relay is closed (active).
• Sin luz: Indicates the relay is disconnected (inactive).
• If the delay timer is active, the light blinks during the delay, and the relay remains disconnected.

Pantalla de tubo digital

• PV (Red Display): Shows the actual test temperature. Displays error codes like "LLL" (sensor open), "HHH" (measured temperature exceeds max range, relay disconnected), or "----" (high-temperature alarm setting exceeds max value).
• SV (Blue Display): Shows the temperature value at which the relay turns on or off. Press the COLOCAR button to make the SV digital tube flash, then use the Up (▲) y Abajo (▼) arrows to adjust the value.

Configuración del menú principal

1. Mantenga pulsado el COLOCAR button for 3 seconds to enter the main menu settings.
2. Continuar presionando COLOCAR to cycle through modes P0 to P8.
3. Utilice el Up (▲) y Abajo (▼) arrows to adjust the value for the selected mode.
4. To confirm and exit, long press COLOCAR for 3 seconds, or wait 8 seconds for automatic confirmation.

Interruptor de encendido

• Mantenga pulsado el Reanudar button for 1.5 seconds to turn off the display and relay.
• Presione el Reanudar button again for 1.5 seconds to turn on the display.

Mantenimiento

To ensure the longevity and optimal performance of your Coliao W3230 Temperature Controller, regular maintenance is recommended. Keep the device clean and free from dust and moisture. Avoid exposing the unit to extreme temperatures or harsh chemicals. Periodically check the wiring connections to ensure they are secure.

The NTC10K waterproof sensor is designed for durability, but avoid sharp bends or excessive pulling on the wire. If the sensor or wire appears damaged, it should be replaced to maintain accurate temperature readings.

Solución de problemas

This section provides guidance for common issues indicated by the controller's display.

If the module does not respond after a power outage, it should automatically resume operation after power recovery. If issues persist, verify all connections and power supply.
