Application:
The refrigeration controller is designed for automatic temperature control in cold rooms and refrigeration systems. The controller monitors the temperature using a precise Pt1000 sensor and controls the main components of the refrigeration system – the compressor, evaporator fan, and defrost heater.
The set temperature, hysteresis, and cooling parameters can be easily adjusted according to the specific application. The controller automatically switches the compressor on and off based on the measured temperature, ensuring stable maintenance of the required temperature conditions.
Main Features:
- Automatic temperature control within a range of -20°C to +40°C.
- Control of the compressor and evaporator fan.
- Automatic defrost control based on temperature or time.
- Automatic activation of a defrost cycle when the controller is powered on.
- Short fan operation after defrosting to help dry the evaporator.
- 2-minute compressor start delay after power-up or restart, allowing time for pressure equalization within the refrigeration system.
- Adjustable hysteresis for precise temperature control.
- Clear 3-digit digital display showing the set and actual temperature.
- Indicators for operating modes and the status of the controlled outputs.
- Automatic detection of temperature sensor faults.
- Service settings for temperature measurement correction.
