AFTC-ETC-3000. Temperature Controller
The AFTC-ETC-3000 is a high-precision digital temperature controller designed for comprehensive regulation of refrigeration, defrosting, and fan functions. It features a double-sensor input to monitor both cabinet and evaporator temperatures simultaneously.
Technical Specifications
- Temperature Measurement Range: -45.5°C to 120°C.
- Temperature Control Range: -45.5°C to 110°C.
- Resolution: 0.1°C (display).
- Accuracy: ±1°C (typically between -45.5°C and 70°C).
- Power Supply: 220VAC ±10%, 50/60Hz.
- Relay Contact Capacity:
- Compressor: 8A or 10A / 220VAC.
- Defrost & Fan: 8A or 10A / 220VAC.
- Sensors: Two NTC sensors (2 meters each including the probe).
Key Features
- Dual Sensor Input: Dedicated probes for cabinet temperature and defrost termination temperature (evaporator).
- Multi-Mode Control: Independent management of compressor, defrost heater, and fan.
- Protection Functions: Includes compressor start-up delay (default 1 minute) and temperature calibration.
- User & Administrator Menus: Settings are divided to allow separate access for basic operation and high-level configuration.
- Alarms: Built-in buzzer and flashing display for over-temperature limits or sensor failure (e.g., “HHH” or “LLL”).
- CopyKey Function: Allows rapid duplication of parameters across multiple units using an external copy card.
Wiring Overview
According to standard ETC-3000 diagrams:
- Terminals 1 & 2: Power supply input (220VAC).
- Terminal 3: Output relay for the compressor.
- Terminal 4: Output relay for the evaporator fan.
- Terminals 5 & 6: Output relay for the defrost heater.
- Terminals 7 & 8: Connections for the two NTC temperature probes.
- Terminal 9: Port for the CopyKey interface.
Basic Operation
- Unlock Keypad: Press and hold the Up (▲) and Down (▼) keys simultaneously for 10 seconds.
- View Setpoint: Press the SET key briefly in normal mode.
- Manual Defrost: Press and hold the UP (▲) key (or designated defrost key) for 3–5 seconds.
