Indledning
This manual provides comprehensive instructions for the installation, operation, and maintenance of the Subzero SZ-7569T Touch Sensitive Temperature Controller. Please read this manual thoroughly before using the device to ensure proper function and safety.
Produkt overview
The Subzero SZ-7569T is a next-generation touch-sensitive temperature controller designed for various refrigeration and heating applications. It features an improved IP rating, an iconic display, and a user-friendly touch interface. This controller incorporates safety features for compressor protection, operating by cutting off the compressor at the set point and restarting it at a temperature of set point plus differential.
Figure 1: Subzero SZ-7569T Front Panel
This image displays the Subzero SZ-7569T Touch Sensitive Temperature Controller. The front panel features a large red digital display indicating the current temperature, along with touch-sensitive buttons for power, navigation (up/down for programming), and setting parameters. The 'Sub-Zero' brand logo is visible on the left side of the panel. The top edge shows a label with model number 7569-P and electrical specifications.
Nøglefunktioner

- Improved IP Rating: Offers enhanced protection against environmental factors.
- Iconic Display: Clear and easy-to-read digital temperature display.
- Compressor Safety Features: Designed to protect the compressor during operation.
- Bredt måleområde: Kan måle temperaturer fra -45°C til 99°C.
- Non-volatile EEPROM Memory: Retains data even during power loss.
Opsætning og installation
Vigtig: Installation should only be performed by qualified personnel. Ensure power is disconnected before beginning installation.
- Montering: Install the controller in a suitable panel cutout. The frontal dimensions are 78 X 36mm.
- Elektriske forbindelser: Use screw terminal blocks for wiring. Ensure wires are less than 2.5 sq mm. Refer to the wiring diagram (typically found on the device casing or separate diagram) for correct connections for power supply (230 Vac ±15 %, 50-60Hz) and compressor relay output (20(8)A, 250V AC).
- Probeforbindelse: Connect the temperature probe to the designated terminals.
- Tænd: Once all connections are secure, apply power to the unit.
Betjeningsvejledning

Opretholdelse
To ensure optimal performance and longevity of your Subzero SZ-7569T controller, follow these maintenance guidelines:
- Rensning: Regularly clean the front panel with a soft, damp klæde. Brug ikke slibende rengøringsmidler eller opløsningsmidler.
- Inspektion: Periodically check all electrical connections for tightness and signs of wear or damage.
- Miljøforhold: Sørg for, at driftsmiljøet forbliver inden for de angivne temperatur- og fugtighedsområder for at forhindre skader.
Fejlfinding
If you encounter issues with your SZ-7569T controller, consider the following common troubleshooting steps:
- Intet display/Ingen strøm:
- Kontroller strømforsyningsforbindelsen og sørg for, at den er inden for den specificerede voltage range (230 Vac).
- Verify that the power switch (if external) is in the ON position.
- Forkert temperaturaflæsning:
- Ensure the temperature probe is correctly connected and not damaged.
- Verify the probe is placed in the correct location for accurate measurement.
- Compressor Not Activating/Deactivating:
- Check the set point and differential settings in the programming mode.
- Inspect the compressor relay connections.
- Ensure the compressor itself is functional.
