Coliao W3230 Digital Temperature Controller User Manual

Okwu mmalite

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.

Ntọala na Waya

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.

Ihe dị mkpa: Ensure the working power supply voltage matches the label on the product.

Ntuziaka ọrụ

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.

• Na-egbuke egbuke: Indicates cooling or heating start-up delay.
• Ìhè Na-adịgide Adịgide: Indicates the relay is closed (active).
• Enweghị ọkụ: Indicates the relay is disconnected (inactive).
• If the delay timer is active, the light blinks during the delay, and the relay remains disconnected.

Nlekọta

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.

Nchọpụta nsogbu

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.
