W3230 AC110-220V Digital Temperature Controller with 1m Sensor

The W3230 Digital Temperature Controller is a compact microcomputer-based thermostat designed for automatic temperature monitoring and control. Operating with a compatible AC 110–220V supply, it uses an external temperature sensor to measure the surrounding environment or a suitable target and switches connected equipment according to the configured temperature settings.

The controller features a digital LED display and front-panel buttons for adjusting the target temperature, operating mode, and switching differential. It supports both heating and cooling applications, allowing it to control equipment such as heaters, cooling fans, and refrigeration systems. The included 1-meter sensor cable provides flexibility when positioning the temperature probe away from the controller.

The W3230 is suitable for DIY electronics, temperature-controlled enclosures, incubators, aquariums, greenhouses, and workshop projects. Its compact panel-mount design makes it convenient for installation in compatible equipment housings and control panels. By automatically switching the connected load according to the measured temperature, it helps maintain a defined temperature range without continuous manual adjustment.

The controller's performance depends on sensor placement, the thermal characteristics of the application, and the connected load. Before installation, verify the exact model's relay rating and terminal connections. For inductive loads, high starting currents, or applications requiring continuous operation at high current, an appropriately rated external contactor may be necessary.
