  • How do I change the Setpoint on the AD2-28 controller?

    Press the Info/Setpoint button for at least half a second to display the current value. While holding the button, use the Increase or Decrease buttons to adjust the value, then release to store the new setpoint.

  • How can I manually start a defrost cycle?

    You can manually initiate a defrost by pressing the 'Manual defrost / Decrease' button for 2 seconds, provided the conditions for defrost are met and the function is enabled.

  • What does the Keypad Lock function do?

    The keypad lock (LOC=YES in the INFO menu) inhibits the function of all buttons to prevent unauthorized or accidental changes to the controller settings in public or secure areas.

  • How do I switch between parameter groups?

    If enabled (IISM=MAN), you can manually switch between Group I and Group II parameter sets by pressing the relevant button for 2 seconds. Switchover can also occur automatically under specific heavy-duty conditions if configured.
