STC-1000 Digital Temperature Controller Dual Relay NTC Sensor
STC-1000 Digital LED Temperature Controller with Dual Relay Output & NTC Sensor Probe
Take precise control of your heating and cooling systems with the STC-1000 Digital Temperature Controller. Featuring a bright LED display, dual relay outputs, and a high-accuracy NTC sensor probe, this compact thermostat is the go-to solution for homebrewers, aquarium enthusiasts, greenhouse growers, HVAC projects, and industrial automation setups. Compatible with both AC power (110–220V) and DC 12V/24V systems, it fits seamlessly into almost any environment.
Key Features
- Wide Temperature Range: Measures and controls from -50°C to +110°C with 0.1°C resolution for fine-tuned accuracy.
- Dual Relay Output: Independent heating and cooling relay outputs (10A/240VAC each) allow simultaneous or separate control of two devices.
- Flexible Power Supply: Operates on 110–220VAC (±10%, 50/60Hz) or DC 12V, making it versatile for a wide range of applications.
- Imported NTC Sensor Probe: Comes with a 1-meter NTC sensor probe for responsive and accurate temperature readings.
- Easy Parameter Setting: Press and hold the SET button for 5 seconds to access internal parameters (P0–P8). Navigate with Up/Down buttons and confirm with RST.
- CE Certified: Meets CE certification standards for safety and reliability.
- Compact & Durable: Housed in an ABS flame-retardant plastic shell; lightweight at just 100g and available in a sleek gray finish.

Frequently Asked Questions
Q: Can the STC-1000 Digital Temperature Controller work with both heating and cooling devices simultaneously?
A: Yes! The STC-1000 features two independent relay outputs — one dedicated to heating and one to cooling — each rated at 10A/240VAC. This allows you to connect and independently control both a heating element and a cooling device (such as a fan or refrigeration unit) at the same time, making it ideal for fermentation chambers, aquariums, and climate-controlled enclosures.
Q: Is the STC-1000 compatible with DC 12V systems, or does it only work on AC power?
A: The STC-1000 is compatible with both AC power (110–220VAC, 50/60Hz) and DC 12V, offering excellent versatility for use in vehicles, off-grid setups, and low-voltage projects in addition to standard household and industrial AC applications.
Q: How do I access the advanced settings on the STC-1000 thermostat?
A: To enter the internal parameter settings (P0–P8), simply press and hold the SET button for 5 seconds. Use the Up and Down arrow buttons to navigate between parameters, and press the RST button to confirm your selection and return to the main display. This makes it straightforward to customize hysteresis, alarm thresholds, and other control settings to suit your specific application.
