STC-1000 – Professional Digital Thermostat with Heating and Cooling
STC-1000 is one of the most popular digital temperature controllers, ideal for HVAC projects, refrigerators, cold rooms, fermentation, radiator control, and industrial applications. It operates on AC 110–220V and provides precise control between -50 and 99°C, using a waterproof NTC 10K sensor.
Main Functions
- Dual Control: heating mode + cooling mode (2 independent relays).
- Clear LED Display, easy to configure.
- Compressor Protection – configurable delay (F3).
- Alarm for temperature exceedance or sensor error.
- Temperature Calibration (F4) ±10°C.
- High Accuracy: ±0.2°C, resolution 0.1°C.
- Low Power Consumption: <3W.
Advantages and Benefits
- Maintains the temperature at the set value with excellent accuracy.
- The waterproof NTC 10K sensor allows use in humid or wet environments.
- Ideal for automatic temperature maintenance in critical systems.
- Fire-resistant ABS plastic for enhanced safety.
- Stable operation under high humidity (20–84%).
Operating Mode
Heating Mode: the relay turns on when the temperature is below the set value (F1) and turns off when it exceeds it.
Cooling Mode: the relay turns on when the temperature exceeds the set value (F1) and turns off when it drops below it.
Recommended Applications
- Temperature control for modified refrigerators, freezers, and cold rooms.
- Automated temperature control in boiler rooms, technical rooms, and utility spaces.
- Automatic control for electric radiators, fan heaters, and heating panels.
- HVAC and ventilation systems – fan activation based on temperature.
- Temperature control in electrical cabinets, servers, racks, and electronic equipment.
- Maintaining temperature in mini-greenhouses, germination zones, or plant areas.
- Control for food dryers (DIY dehydrators).
- Control for fermentation of beer, wine, yogurt, or kefir.
- Automation for industrial equipment requiring heating and cooling switching.
- Maintaining temperature for aquariums or water containers.
