2. Varnostne informacije

Adherence to safety standards is crucial for the proper functioning and longevity of the device, as well as for user safety. This controller complies with relevant European standards.

• Priključni kabli: Ensure connection cables guarantee insulation up to 90°C.
• 12 Vac Versions: For 12 Vac versions, use Class II transformers. To comply with immunity standards, the transformer must be a specified CAREL model. Double insulation cannot be guaranteed between power supply and relay outputs for 12 Vac/dc versions; use only safety low voltage loads (up to 42 V effective rated value).
• Dovoljenje za namestitev: Maintain a space of at least 10 mm between the case and nearby conductive parts.
• Digital and Analog Input Connections: For connections less than 30 m away, adopt suitable measures for separating cables to ensure compliance with immunity standards.
• Output Cable Security: Secure the connection cables of the outputs to avoid contact with very low voltage deli.

5. Delovanje

The Carel PZGXS0J111 features an intuitive interface with a 3-digit LED display and several buttons for control and configuration.

5.1 Display and Functions

The display shows the value of the probe set using parameter P1. An ambient probe, defrost probe, and third probe are available. LEDs indicate the activation of control functions.

5.2 Button Functions (Models S, X, Y, C)

5.3 Setting the Set Point (Desired Temperature)

• Pritisnite NASTAVI for 1 s; the set value will start flashing after a few moments.
• Increase or decrease the value using UP (▲) ali DOL (▼).
• Pritisnite NASTAVI za potrditev nove vrednosti.

5.4 Switching the Device ON/OFF

Pritisnite ON/OFF (⏻) for more than 3 s. The control and defrost algorithms are now disabled and the instrument displays the message "OFF" alternating with the temperature read by the set probe.

5.5 Manual Defrost (Models S, X, Y and C only)

Pritisnite DEFROST (❄️💧) for more than 3 s (the defrost starts only if the temperature conditions are valid).
