EK-3020. REF. Temperature Controller.
The EK-3020 is a microcomputer-based digital temperature controller primarily used for regulating refrigeration and defrost functions in equipment like cold storage, air-cooled cabinets, and refrigerated display cases.
Technical Specifications
- Measurement Range: -40°C to 99°C.
- Control Range: -40°C to 85°C.
- Accuracy: ±1°C between -30°C and 50°C; ±2°C for other ranges.
- Resolution: 0.1°C or 1°C.
- Power Supply: 220VAC ±10%, 50/60Hz.
- Output Capacity:
- Refrigeration: 10A/220VAC (can drive 1HP single-phase compressor directly).
- Defrost: 10A/220VAC.
- Sensor Type: NTC probe (10KΩ/25°C), 2 meters in length.
- Mounting Size: 71mm x 29mm.
Key Features
- Touch Interface: Six high-precision capacitive touch keys with an automatic key lock function (locks after 30 seconds of inactivity).
- Safety & Protection:
- Alarms: Built-in buzzer for over-temperature and sensor failure (E1 code).
- Durability: IP65 waterproof and dustproof front panel protection.
- Special Functions:
- One-Key Recovery: Allows users to quickly reset to factory default parameters.
- Defrost Memory: Remembers the defrost cycle even after unexpected power failure to ensure consistent cooling efficiency.
- Forced Defrost: Manual override to initiate a defrost cycle.
Operation & Programming
- To Unlock: Press the OK/Unlock key for about one second until the buzzer beeps.
- Set “On Temp”: Press the On Temp button, adjust with arrow keys, and press OK to save.
- Set “Off Temp”: Press the Off Temp button, adjust with arrow keys, and press OK to save.
- System Menu: Press and hold OK for more than 5 seconds to enter advanced settings (parameters F1–F5).
