After wiring, apply power to the controller. The display should illuminate, showing the current temperature or an initial setup prompt.
5. Instruccions de funcionament
The AKO D-14323 offers various programmable parameters to suit different refrigeration needs.
5.1 Funcionament bàsic
- Visualització de la temperatura: The main display shows the current temperature measured by the primary sensor.
- Botó SET: Premeu per view or modify the setpoint temperature. Hold to enter parameter programming mode.
- Botó ESC: Used to exit menus or cancel changes.
- Fletxes amunt/avall: Used to adjust values in programming mode or manually initiate defrost (if configured).
- Botó d'encesa: Turns the unit on/off or acts as a reset in some configurations.
5.2 Configuració del punt de consigna de temperatura
- Premeu el botó SET button briefly. The current setpoint will flash.
- Utilitza el Up or Avall botons de fletxa per ajustar la temperatura desitjada.
- Premeu SET again to confirm and save the new setpoint, or ESC per sortir sense desar.
5.3 Advanced Parameter Programming
To access advanced parameters (e.g., defrost cycles, differential, auxiliary relay functions), hold the SET button for several seconds until the first parameter code appears. Navigate using the arrow buttons and press SET to enter/confirm values. Refer to the detailed programming guide (usually provided separately or available from AKO) for a complete list of parameters and their functions.
5.4 Defrost Cycle Management
The controller supports various defrost methods, including controlling the compressor, resistance heaters, or fans. Defrost parameters can be adjusted to optimize performance based on the application. An optional probe allows defrosting by temperature.
6. Manteniment
Un manteniment regular garanteix un rendiment òptim i allarga la vida útil del controlador de temperatura.
- Neteja: Periodically clean the front panel with a soft, damp tela. No utilitzeu netejadors abrasius ni dissolvents.
