The XH-W3001 Digital LED Temperature Controller is a compact, high-precision thermostat designed for temperature regulation in incubators, aquariums, heating and cooling systems, and industrial control applications. It combines a bright LED display, a waterproof NTC sensor probe, and a high-capacity relay output to deliver reliable, automatic temperature management at a very affordable price point.
At the heart of the controller is a microcomputer-based control circuit that offers temperature control precision up to 0.1°C and a wide measurement range of -50°C to 110°C . The included 1-meter stainless steel NTC10K waterproof probe ensures accurate readings even in humid or wet environments, making it suitable for aquaculture, incubation, and other moisture-prone applications .
The controller features a 10A relay output, capable of directly switching loads up to 1500W at 220V AC (variant dependent) . The output type is direct output, meaning the load must share the same power source as the controller . The device operates on AC 24V (this specific variant) and is housed in a flame-retardant ABS plastic enclosure measuring 59.5 × 44.5 × 31mm .
Setting the temperature is straightforward. The two buttons allow you to set a START temperature (when heating/cooling activates) and a STOP temperature (when it deactivates). The operating mode is determined automatically: if START < STOP, the controller operates in heating mode; if START > STOP, it operates in cooling mode . The two setpoints must be at least 2°C apart for proper operation .
The controller is widely used in incubation, aquarium temperature control, seafood machines, greenhouse management, equipment enclosures, and cabinet cooling systems . Its compact form factor, panel-mount design (with mounting ears), and simple two-button operation make it a practical choice for both hobbyists and commercial installations.
Whether you are building an incubator, managing an aquarium, or adding temperature protection to equipment, the XH-W3001 provides a proven, cost-effective solution. It is suitable for individual makers, students, and businesses purchasing in bulk for product development or educational programs.
