6.2 eserese waya

Refer to the following wiring diagrams for connecting the temperature controller. It is crucial to distinguish between the power supply, sensor, and load connections, and to maintain proper distance between wires to avoid interference.

• Load Independent Power Supply: In this configuration, the controller's power supply and the load's power supply are separate. Connect the controller's power (L and N) to its designated terminals. Connect the sensor to the sensor terminals. The output terminals (for the load) are then connected to the load's power supply and the load itself.
• Same Load Power Supply: Here, the controller and the load share the same power supply. Connect the main power (L and N) to the controller's power input. The sensor connects to its terminals. The output terminals for the load will then connect to the load, drawing power from the same source as the controller.

Mara: Always ensure correct polarity and secure connections. Incorrect wiring can damage the device or pose a safety risk.

• PV Temperature Detection Value (Red Display): Shows the current measured temperature.
• SV Temperature Setting Value (Blue Display): Shows the target temperature set by the user.
• OUT Indicator Light: Illuminates when the output relay is active (heating or cooling).
• °C/°F Indicator Light: Indicates the current temperature unit.
• Tọọ bọtịnụ: A na-eji ya edebanye ma kwado ntọala paramita.
• bọtịnụ elu (▲): Used to increase values or navigate menu options.
• bọtịnụ ala (▼): Used to decrease values or navigate menu options.
• Rst Button (Reset): Used to reset settings or exit menus.

7.2 Setting Temperature Parameters

To set the desired temperature and other operational parameters:

1. Tinye Ụdị Ntọala: Pịa ma jide Tọọ button for approximately 3 seconds until the SV display starts flashing.
2. Hazie okpomọkụ: Jiri ihe Elu (▲) or Ala (▼) buttons to adjust the desired target temperature.
3. Confirm Set Temperature: Pịa Tọọ button again to confirm the temperature and move to the next parameter (if any) or exit the setting mode.
4. Advanced Parameters (if applicable): Some models may have additional parameters like hysteresis, calibration, or delay. These are typically accessed by pressing and holding the Tọọ button for a longer duration or by a specific button combination. Refer to the detailed parameter list for your specific model if available.
5. Ọnọdụ Ntọala Pụọ: If no further adjustments are needed, wait for a few seconds, and the controller will automatically exit the setting mode, saving the changes. Alternatively, press the Rst button to exit without saving changes if you are in a sub-menu.

7.3 Temperature Unit Conversion (°C/°F)

Ka ịgbanwee n'etiti Celsius (°C) na Fahrenheit (°F), pịa ma jide Elu (▲) button for approximately 3 seconds. The corresponding indicator light will illuminate.

8. Nlekọta

• Nhicha: Wipe the controller's surface with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Nyocha ihe mmetụta: Periodically check the NTC sensor and its cable for any signs of damage or corrosion. Ensure it is securely placed in the area where temperature is to be measured.
• Igwe ikuku: Ensure that the ventilation slots on the controller are not obstructed to allow for proper heat dissipation.
