పరిచయం
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.

సెటప్ మరియు వైరింగ్
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.

ముఖ్యమైన: Ensure the working power supply voltage matches the label on the product.
ఆపరేటింగ్ సూచనలు
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.
సూచిక స్థితి
- ఫ్లాషింగ్: Indicates cooling or heating start-up delay.
- స్థిరమైన కాంతి: Indicates the relay is closed (active).
- కాంతి లేదు: Indicates the relay is disconnected (inactive).
- If the delay timer is active, the light blinks during the delay, and the relay remains disconnected.
డిజిటల్ ట్యూబ్ డిస్ప్లే
- 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 సెట్ button to make the SV digital tube flash, then use the Up (▲ ▲ తెలుగు) మరియు క్రిందికి (▼) arrows to adjust the value.

| హెచ్చరిక కోడ్ | లోపానికి కారణం | పరిష్కారం |
|---|---|---|
| HHH | ఉష్ణోగ్రత అలారం ఉష్ణోగ్రత లేదా గరిష్ట కొలత పరిధిని మించిపోయింది. | Ensure the measured temperature is within the operating range (-50℃ to 120℃). If the temperature is too high, allow it to drop below the alarm threshold. The relay will be forcibly disconnected. |
| LLL | ఉష్ణోగ్రత సెన్సార్ కనుగొనబడలేదు లేదా సెన్సార్ ఓపెన్ సర్క్యూట్ లేదు. | Check the sensor connection. If the connection is secure, the sensor may be faulty and requires replacement. |
| ---- | అధిక-ఉష్ణోగ్రత అలారం సెట్టింగ్ గరిష్ట విలువను మించిపోయింది. | Adjust the high-temperature alarm setting to be within the permissible range of the device. |
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.
