AFTC-ETC-902 REF.Temperature Controller
The AFTC-ETC-902 is a microcomputer-based digital temperature controller designed for simple single-stage refrigeration or heating applications. It is widely used in beverage cabinets, display cases, and kitchen refrigerators.
Technical Specifications
- Measurement & Control Range: -50°C to +99°C (Standard). Some models support up to +120°C with NTC sensors or +150°C with PTC sensors.
- Accuracy: ±0.5°C (between -30°C and +50°C); ±1°C for other ranges.
- Resolution: Selectable between 0.1°C and 1°C.
- Power Supply: 230VAC ±10%, 50/60Hz.
- Relay Output: 1 output (SPDT), typically rated for 8A or 10A at 220VAC/250VAC.
- Sensor Type: Supports NTC or PTC probes (one 2m NTC probe is typically included).
- Dimensions: 77mm x 34.5mm (Mounting hole: 71mm x 29mm).
Key Features
- Dual Mode: Can be programmed for either cooling (refrigeration) or heating.
- User Interface: Three-digit LED display with status indicators and four touch-sensitive keys (Up, Down, SET, FNC).
- Copy Card Function: Allows quick parameter copying for batch equipment manufacturing or service.
- Safety Alarms: Built-in alerts for over-temperature limits and sensor errors.
- Protection: Front panel is typically rated IP65 (dust and water-resistant).
Basic Operation & Programming
- View Setpoint: When the current temperature is displayed, press SET once to see “Set,” then press SET again to view the current setpoint.
- Modify Setpoint: While viewing the setpoint, use the Up (︽) or Down (︾) keys to adjust. Press FNC to save and exit.
- Access Parameter Menu: Press and hold SET for at least 5 seconds. If a password (PA1) is active, you must enter it (standard default is often 000 or 111) to access parameter folders like CP (Regulator) or diS (Display).
Wiring Overview
- Power: Terminals for AC supply (typically check the side label for exact terminal numbers, often 3 & 4 for 220V on these units).
- Relay: Output contacts for connecting the load (compressor or heater).
- Sensor: Specific terminals for the NTC probe (no polarity required).
