Coliao W3230 Digital Temperature Controller User Manual

Introducció

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.

Setup and Wiring

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.

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

Instruccions de funcionament

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.

Indicador d'estat

• Parpellejant: Indicates cooling or heating start-up delay.
• Llum constant: Indicates the relay is closed (active).
• Sense llum: 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 tub 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 SET button to make the SV digital tube flash, then use the Up (▲) i Avall (▼) arrows to adjust the value.

Configuració del menú principal

1. Premeu llargament el botó SET button for 3 seconds to enter the main menu settings.
2. Continueu prement SET to cycle through modes P0 to P8.
3. Utilitza el Up (▲) i Avall (▼) arrows to adjust the value for the selected mode.
4. To confirm and exit, long press SET for 3 seconds, or wait 8 seconds for automatic confirmation.

Interruptor d'alimentació

• Premeu llargament el botó Reinicieu button for 1.5 seconds to turn off the display and relay.
• Premeu el botó Reinicieu button again for 1.5 seconds to turn on the display.
