AFTC-STC-9200. REF.Temperature Controller.
The AFTC-STC-9200 is a professional-grade microcomputer temperature controller specifically designed for oversized freezer rooms and complex refrigeration systems. It is a “double sensor” unit, meaning it uses two independent probes to monitor both the storage room temperature and the evaporator temperature for optimized defrosting and fan control.
Technical Specifications
- Measurement & Control Range: -50.0°C to +50.0°C.
- Accuracy: ±1°C (between -40°C and 50°C).
- Power Supply: 220VAC ±10%, 50/60Hz.
- Relay Output Capacity (3 Relays):
- Refrigeration (Compressor): 8A or 10A / 220VAC.
- Defrost: 8A or 10A / 220VAC.
- Evaporator Fan: 8A or 10A / 220VAC.
- Sensors: Two waterproof NTC probes (10KΩ/25°C), typically 2 meters long.
Key Features & Functions
- Triple Load Control: Independently manages the compressor, defrosting unit, and evaporator fan.
- Advanced Defrosting: Controls defrost cycles by both time and temperature. It terminates defrosting once the evaporator reaches a set “stop temperature” (parameter F8) to prevent unnecessary heating.
- Intelligent Fan Management: Offers multiple fan modes, such as continuous operation, starting/stopping with the compressor, or temperature-controlled starts.
- Menu Separation: Features a “User Menu” for basic temperature adjustments and a password-protected “Administrator Menu” for deep system configuration.
- Copy-Key Support: Includes a Mini-USB port for rapid batch programming across multiple units.
Wiring Overview
- Port 1: Common live wiring for loads.
- Port 2: Compressor relay output.
- Port 3: Defrosting relay output.
- Port 4: Evaporator Fan relay output.
- Ports 5 & 6: Power supply input (220VAC).
- Port 7: Storage room temperature sensor.
- Port 8: Common point (Co-point) for both sensors.
- Port 9: Evaporator/Defrost temperature sensor.
Basic Operation Guide
- Unlock Keypad: Press the Up (▲) and Down (▼) keys simultaneously for 10 seconds until it unfreezes.
- Adjust Target Temp: Press and hold SET for 2 seconds, use the arrows to adjust, then press SET again to save.
- Manual Defrost: Press and hold the Down (▼) key (or designated defrost key) for 3–5 seconds.
- Error Codes: E1 indicates a room sensor failure; E2 indicates an evaporator sensor failure.
