AFTC-STC-9100. REF.Temperature Controller
The AFTC-STC-9100 is a high-precision, double-sensor microcomputer temperature controller. It is specifically designed for medium and low-temperature refrigeration systems that require independent management of cooling, defrosting, and alarm functions.
Technical Specifications
- Measurement Range: -50.0°C to 90.0°C.
- Control Range: -50.0°C to 50.0°C.
- Accuracy: ±1°C between -40°C and 50°C; ±2°C for other ranges.
- Resolution: 0.1°C or 1°C.
- Power Supply: 220VAC ±10%, 50/60Hz.
- Output Capacity (3 Relays):
- Refrigeration: 8A / 220VAC.
- Defrost: 8A / 220VAC.
- External Alarm: 8A / 220VAC.
- Sensors: Two NTC sensors (one for cabinet temperature, one for evaporator temperature).
Key Features
- Independent Controls: Manages the compressor and defrost heaters separately, with a dedicated third relay for external alarms.
- Defrost Management: Supports multiple defrost termination modes (based on time or evaporator temperature) and types (electric or hot gas).
- Dual Sensors: Provides accurate cooling control and ensures defrosting only occurs when necessary by monitoring the evaporator directly.
- Protection: Includes a compressor start-up delay and a front panel rated IP65 (water and dust resistant).
- Safety Alarms: Features a built-in buzzer and visual alerts for over-temperature limits and sensor failures (E1 or E2).
- Copy Card Port: Includes a dedicated interface for rapid parameter duplication across multiple units.
Basic Operation
- View Setpoint: Press and release the SET key briefly to see the target temperature.
- Access Administrator Menu: Press and hold SET for more than 3 seconds. Use the arrow keys to navigate parameter codes like St (Set point) or hy (Hysteresis).
- Manual Defrost: Press and hold the UP (▲) key (often marked with a snowflake) for 5 seconds to manually initiate a cycle.
Wiring Overview
- Terminals 1 & 2: Power supply input (220VAC).
- Terminal 3: Common line for relays.
- Terminal 4: Refrigeration (Compressor) output.
- Terminal 5: Defrosting output.
- Terminal 6: Alarm output.
- Terminals 7–10: Inputs for the two NTC temperature probes.
