STC-1000. Temperature Controller.
The STC-1000 is a highly popular, dual-purpose digital microcomputer temperature controller. It is versatile enough for refrigeration (cooling) and heating applications, making it a staple for aquariums, incubators, homebrewing, and small-scale cold storage.
Technical Specifications
- Measurement Range: -50.0°C to 99.9°C.
- Accuracy: ±1°C (between -50°C and 70.0°C).
- Resolution: 0.1°C.
- Power Supply: 220VAC ±10%, 50/60Hz.
- Relay Output Capacity: 10A / 250VAC.
- Sensor Type: One NTC probe (10KΩ/25°C), 2 meters long.
- Mounting Size: 71mm x 29mm.
Key Features
- Automatic Switching: Automatically switches between heating and cooling modes based on your set temperature and differential values.
- Dual Status Indicators: Features dedicated “Cool” and “Heat” LEDs on the front panel to show which relay is currently active.
- Equipment Protection: Includes a programmable compressor start-up delay (0–10 minutes) to prevent short-cycling.
- Safety Alarms: Built-in buzzer for sensor failure (Error Code EE) or when the temperature exceeds the measurement range.
- Calibration: Allows for temperature adjustment to match a reference thermometer.
Programming Guide (Parameter Codes)
To enter the menu, press and hold the S (Set) key for 3 seconds. Use the Up/Down arrows to navigate:
| Code | Function | Range | Default |
|---|---|---|---|
| F1 | Temperature Setpoint (Target) | -50.0 to 99.9°C | 10.0°C |
| F2 | Difference Value (Hysteresis) | 0.3 to 10.0°C | 0.5°C |
| F3 | Compressor Delay Time | 1 to 10 minutes | 3 min |
| F4 | Temperature Calibration | -10.0 to +10.0°C | 0.0°C |
Basic Operation
- View Setpoint: Briefly press the Up (▲) key during normal operation.
- View Hysteresis: Briefly press the Down (▼) key during normal operation.
- Change Parameters: While in the F1–F4 menu, hold S and use the Up/Down arrows to change the value. Press the Power button briefly to save.
