5. Setup and Installation

The STC-3000 is designed for panel mounting. Follow these steps for proper installation and wiring:

5.1 Panel Mounting

• Cut a rectangular opening in your panel with dimensions approximately 71mm x 29mm (2.80in x 1.14in).
• Insert the controller into the opening.
• Secure the controller using the orange mounting clips on the sides. Push them inwards until they lock into place against the panel.

5.2 Wiring Diagram

Refer to the diagram below for correct wiring connections. Ensure all connections are secure and insulated.

Figure 5.1: STC-3000 Wiring Diagram

This image displays the wiring diagram located on the back of the STC-3000 controller. It clearly labels terminals for "Power Input" (1, 2), "Sensor" (3, 4), and "Load" (5, 6), indicating how to connect the power supply, temperature sensor, and the device to be controlled (e.g., heater or cooler).

• Power Input (Terminals 1 & 2): Connect your AC power supply (110V-220V) to these terminals.
• Sensor (Terminals 3 & 4): Connect the NTC temperature sensor probe to these terminals. The sensor is non-polar, so connection order does not matter.
• Load (Terminals 5 & 6): Connect the device you wish to control (e.g., heater, cooler, fan) to these terminals. This is a relay output, acting as a switch. Ensure the load's power requirements do not exceed the controller's maximum current rating (10A or 30A).

6. Operating Instructions

The STC-3000 features a user-friendly touch interface. Here's how to operate it:

6.1 Button Functions

• SET: Enters/Exits parameter setting mode. Short press to view current set temperature. Long press (3 seconds) to enter parameter setting.
• RST: Resets the controller. Long press (3 seconds) to restore factory settings.
• ▲ (Up Arrow): Increases parameter value or navigates up in menus.
• ▼ (Down Arrow) / OK: Decreases parameter value or navigates down in menus. Also acts as an "OK" button to confirm settings when in parameter mode.

6.2 Setting Temperature

1. Short press the SET button. The display will show the current set temperature.
2. Long press the SET button for 3 seconds until the display flashes.
3. Use the ▲ or ▼ buttons to adjust the desired temperature setpoint.
4. Press the SET button again or wait 5 seconds for the setting to be saved automatically and return to normal display mode.

6.3 Parameter Settings (Advanced)

Long press SET for 3 seconds to enter parameter setting mode. Use ▲ and ▼ to navigate between parameters (P0-P6). Press SET to select a parameter, then use ▲ and ▼ to adjust its value. Press SET again to confirm and move to the next parameter, or wait to exit.

Note: The specific default values and ranges might vary slightly between production batches. Always refer to the on-screen display for the exact options.

7. Maintenance

To ensure the longevity and accurate performance of your STC-3000 controller, follow these maintenance guidelines:

• Cleaning: Wipe the display and casing with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Sensor Care: Keep the temperature sensor probe clean and free from debris. Avoid bending or damaging the sensor cable.
• Connections: Periodically check all wiring connections to ensure they are tight and free from corrosion. Disconnect power before checking connections.
• Environment: Ensure the operating environment remains within the specified temperature and humidity ranges to prevent damage.
