temperature controller 220v ac stc-1000

The STC‑1000 is a popular, low‑cost, microprocessor‑based digital temperature controller designed to regulate heating and cooling devices. Powered directly from 220V AC mains, it uses a temperature sensor probe to measure ambient temperature and automatically switches connected appliances ON or OFF based on user‑defined setpoints. It is widely used in aquariums, incubators, fermentation chambers, and DIY automation projects.

🔹 Key Specifications

• Power Supply: 220V AC
• Display: Red LED digital display (shows real‑time temperature)
• Sensor: NTC waterproof probe (typically 2–3 meters cable)
• Temperature Range: −50°C to +99°C
• Accuracy: ±1°C
• Relay Outputs:
  • Heating control (up to 10A)
  • Cooling control (up to 10A)
• User Interface: 4 front buttons for setting temperature, hysteresis, and calibration
• Modes: Heating mode (activates when temp < setpoint) and Cooling mode (activates when temp > setpoint)

🔹 Features

• Dual Relay Control: Can manage both heater and cooler simultaneously.
• Compact Design: Panel‑mountable, easy to install.
• Adjustable Settings: User can set desired temperature range and hysteresis.
• Safety Functions: Sensor error detection, delay protection for compressor.
• Versatile Use: Works with resistive loads (heaters, lamps) and inductive loads (fans, compressors).

🔹 Applications

• Aquariums and terrariums
• Incubators (egg hatching)
• Greenhouses and hydroponics
• Food storage and refrigeration units
• Home brewing and fermentation chambers
• Industrial temperature monitoring

✅ In summary: The STC‑1000 (220V AC) is a reliable, affordable digital temperature controller with dual relay outputs, making it ideal for projects that require both heating and cooling regulation in one compact unit.
