CAREL-2N01-Refrigeration-Controller-product

The refrigeration controller with built-in “wizard”
Designed for both field replacements and new installations, simple to use thanks to native BLUETOOTH and NFC connectivity. Installers can use their smartphone with APPLICA for configuration, testing, and maintenance of the controller, while the end users can optimize everyday tasks (such as recording HACCP data) with CONTROLLA.

New smartphone features for installers

  • easy controller configuration using the Wizard
  • save, export, edit, share and import favorite configurations;
  • controller and alarm management, direct commands, LIVE graph/temperature log;
  • TEST mode for managing connected loads

Aesthetics and usability

Slim and elegant for perfect aesthetic integration and simplified cleaning; capacitive touchscreen and immediate navigation with backlit single-function keys.

Wide range of applications

  • Controllers with 2, 4, or 6 relays;
  • Small and Large format;
  • Compatibility with NTC, PTC, and PT1000 probes;
  • Humidity measurement and management (optional);
  • RS485 or TTL port for connection to the supervisory system;
  • Modbus or CAREL protocol.CAREL-2N01-Refrigeration-Controller-fig- \(1\)

Installers save time in the field
Easy configuration using the Wizard, immediate and intuitive interaction with the multi-language app.

Simplified management for distributors
Less models that cover most applications with highly-recognizable packaging.

Ready-to-use solution for end users
Easy interaction thanks to direct commands (set point, on-off, defrost) and simplified everyday tasks (such as HACCP recording) using the CONTROLLA app.

Interaction with the controller

iJW can be configured and controlled via the front keypad in the same way as traditional products, or via smartphone, using the NFC or Bluetooth connection. The NFC connection can be used to read and modify the iJW status by simply placing the smartphone alongside the controller. The Bluetooth connection, on the other hand, provides continuous communication, in real- time, for all the control functions, as listed in the table below.

  • Let the Wizard guide you through the most suitable configuration. Then integrate and optimize it based on your experience.
  • Save your favorite configurations, share them via email or IM and import them onto other iJW controllers.
  • Test correct unit operation through analysis of the variables in real-time and testing the connected loads.
  • View the temperature and controller status, and access simple routine commands without any risk of inadvertently changing the operating parameters.
  • Graphically displays the temperature/humidity logs and downloads the HACCP records.

iJW is suitable to be included in a 4.0 system thanks to the BMS port (RS485) for connection to a supervisory system. If the TTL port is available, the TTL/ RS485 converter (BXOPZI4850000) or a similar device can be used.
