The electronic refrigeration controller for panel installation in the format 76 x 36 mm has 2 measuring inputs and 4 relays. The power supply is AC/DC 12..24 V +15/-15%, 48..63 Hz. The electronic refrigeration controller is suitable for use in cold rooms, refrigerated display cases or refrigerated counters for connection to resistance thermometers Pt100, Pt1000, KTY1X-6 or KTY2X-6. The temperature of the cold room is recorded via the first measuring input. The second measuring input records the temperature of the evaporator and ends the defrosting process as soon as the defrost limit is reached. The measured values and parameters are shown on a three-digit backlit display. There are 3 relays available for the cooling unit, defrost heater and fan. Alarms can optionally be issued via a relay or a built-in buzzer. The switching states of the relays are signaled via LEDs. Other options include 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 via screw terminals. The device is operated and parameterized using 4 buttons.
