Description
This electronic refrigerator controller for installation in control panels in the format 76 x 36 mm, has 2 measurement inputs and 4 relays. The voltage supply is AC/DC 12..24 V +15/-15%, 48..63 Hz. The electronic cold controller is suitable for use in cold rooms, cooling display cabinets or cold counters for connection to the resistance thermometers Pt100, Pt1000, KTY1X-6 or KTY2X-6. Over the first measurement input the temperature of the refrigerator is covered. The second measurement input measures the temperature of the evaporator and terminates the defrost when the respective limit is reached. The measured values and parameters are displayed on a three-digit background-lit display. There are 3 relays for the cooling unit, defrosting heater and fan available. Alarms can be optionally emitted via a relay or a built-in buzzer. LEDs signal the switching status of the relay. Other options are a data logger with adjustable recording interval for HACCP-compliant documentation, an RS 485 interface and a real-time clock. The electrical connection is made with screw terminals. The device is operated and parameterized via 4 buttons.
