XH‑W3103 Digital Temperature Controller High Power Thermostat Switch With NTC Sensor Probe For Incubator Greenhouse Heating Cooling Control

XH‑W3103 Digital Temperature Controller

📌 Product Overview

The XH‑W3103 is a high‑precision intelligent digital temperature thermostat equipped with a multi‑color LED triple‑display screen and a 2‑meter NTC10KB3950 waterproof temperature probe. It supports optional power supply of DC12V, DC24V and AC220V, with matched output power of 300W, 600W and 5000W respectively. This controller integrates multiple working modes including constant temperature control, intermittent cycle operation, timed shutdown and timed startup, as well as a built‑in temperature calibration function. Featuring simple key operation, wide temperature measurement range and stable control performance, it is widely used in heating and cooling equipment, breeding incubators, aquaculture tanks, industrial equipment and DIY constant‑temperature projects.

🔌 Wiring Description

‑ DC12V / DC24V version: Connect the power supply to the input terminal, and the heating/cooling load to the output terminal, with positive and negative poles distinguished. ‑ AC220V version: Connect mains power to the input terminal, connect the AC load device to the output terminal, no distinction between live wire and neutral wire. ‑ The NTC temperature probe is plugged into the dedicated sensor port for real‑time temperature collection.

⚙️ Working Mode Introduction

‑ Constant Temperature Control Mode: Set start temperature and stop temperature, the controller automatically cuts off or switches on the load to maintain the target temperature. ‑ F1 Intermittent Operation Mode: Set the running duration and pause duration, the device automatically cycles start‑stop operation by minutes. ‑ F2 Timed Shutdown Mode: After the preset running time expires, the controller automatically cuts off the output power. ‑ F3 Timed Startup Mode: After the preset waiting time expires, the controller automatically switches on the load to start working. ‑ Temperature Calibration Mode: Manually compensate the detected temperature value within ‑10℃ ~ +10℃ to eliminate sensor deviation.

🎯 Application Scenarios

‑ Household heating and cooling constant‑temperature control system ‑ Breeding incubator, reptile pet box and poultry hatching equipment ‑ Aquarium, fish tank and water tank temperature management ‑ Industrial equipment constant‑temperature protection and cabinet heat dissipation control ‑ Greenhouse planting, fermentation box, DIY electronic constant‑temperature projects
