      Applications
      • Control of refrigerated counters, display windows and refrigeration units.
      Main characteristics
      • Can be configured for hot or cold applications.
      • Defrosting can be configured for off-cycle, heating element or cycle inversion and frequency and durationcan be set. End-of-defrosting can be based on time or temperature.
      • Clock for programmed defrost (RTC) (on some models).
      • Relay for controlling the compressor, evaporator fans and defrosting elements (defrost output can be configured like light output).
      • Configurable input as evaporator probe or dirty condenser alarm probe.
      • Key operated manual START/STOP defrosting. Key operated ON/OFF.
      • Cold room light ON/OFF switch with key or by means of door switch (if defrost output is configured like cold room light).
      • Display/adjustment of temperature with decimal point.
      • Internal buzzer for acoustic signals.
      • Flat front surface for easy cleaning and keys of ample dimension which can be customized with various colours (on request).
      • High brightness display with increased icons and figures.
      • PEGO programming philosophy guaranteeing immediate start-up.
      • IP65 front protection.
      • Two-fold fastening options: clips / screws. RS485 serial connection with Modbus-RTU or Telenet protocol.
      • Voltage, relay capacity and terminal type depending on model.
      • External transformer for model 3CF11 (optional).
