STC-1000 HW-524B Digital Temperature Controller 24VDC

STC-1000 HW-524B Digital Temperature Controller 24VDC

The STC-1000 HW-524B is a compact and versatile digital temperature controller designed to offer reliable, accurate, and automated temperature control in a variety of environments. Operating on 24V DC, this module is ideal for applications where stable temperature regulation is essential, such as aquariums, incubators, greenhouses, fermentation systems, and small HVAC setups.

Equipped with a dual relay output, the STC-1000 can control both heating and cooling devices simultaneously. This dual-functionality allows users to maintain a precise temperature range by activating either a heater or a cooler depending on the ambient temperature and configured setpoints. The temperature range it supports spans from -50°C to +99.9°C, making it suitable for a wide range of uses, from low-temperature refrigeration to moderate heating applications.

The unit features a 3-digit LED display and simple button-based interface, enabling easy setup of temperature setpoints, hysteresis (differential value), and compressor delay time. These programmable parameters give users fine-grained control over how and when the relays are activated, preventing short cycling and improving the life expectancy of connected devices.

Included with the controller is a waterproof NTC temperature sensor (typically with a 1-meter cable), which provides accurate real-time readings for precise control. The module also includes safety features such as high/low temperature alarms and sensor error detection, adding an extra layer of reliability.

With its compact size, low power consumption, and easy wiring setup, the STC-1000 HW-524B is an ideal choice for both hobbyists and professionals looking to implement efficient thermal control in small-scale projects. Its affordability and reliability have made it a popular choice in DIY electronics, automation, and environmental control systems.

Features: 

• Automatically Controls Heating and Cooling: It intelligently switches between heating and cooling modes based on your desired temperature range.
• Easy to Program: Simple button interface makes it user-friendly — you don’t need technical skills to configure it.
• Real-Time Temperature Monitoring: Continuously displays the current temperature on a bright LED screen, so you always know the system status.
• Fail-Safe Alarms: Built-in alarms notify you if the sensor fails or the temperature exceeds safe limits.
• Customizable Temperature Settings: Lets you define your target temperature and how far the actual temperature can deviate before action is taken.
• Prevents Short Cycling: Built-in delay setting protects compressors or cooling devices from frequent on/off switching, extending their lifespan.
• Compact and Easy to Install: Its small size and clear wiring labels make it ideal for DIY or embedded use in other systems.
• Waterproof Temperature Sensor: Can be used in wet or humid environments like aquariums, fermentation chambers, or greenhouses.
• Energy Efficient: Uses very little power to operate, making it ideal for battery-powered or solar setups.
• Versatile Use Cases: Suitable for many environments — from home brewing and pet enclosures to industrial temperature control setups.
