4. സജ്ജീകരണവും വയറിംഗും

Proper wiring is crucial for the safe and correct operation of the STC-3000. Refer to the wiring diagram below.

Figure 4.1: Wiring diagram for the STC-3000. Terminals 1 and 2 are for power input (Powerinput). Terminals 3 and 4 are for the sensor (Sensor). Terminals 5 and 6 are for the load (Load).

വയറിംഗ് നിർദ്ദേശങ്ങൾ:

1. Power Input (Terminals 1 & 2): Connect your 110-220V AC power supply to these terminals. Ensure the power is off before connecting.
2. Sensor Connection (Terminals 3 & 4): Connect the provided temperature sensor probe to these terminals. The sensor is non-polar, so connection order does not matter.
3. Load Output (Terminals 5 & 6): Connect the device you wish to control (e.g., heater, cooler) to these terminals. The controller acts as a switch for the load.

Note: This thermostat uses a single-pole relay. For 240V applications in regions like the USA where 240V is two 120V phases, only one phase of the load will be switched. Consider using an external dual-pole relay for complete power disconnection of the load if required by your application or local electrical codes.

5. പ്രവർത്തന നിർദ്ദേശങ്ങൾ

5.1 അടിസ്ഥാന പ്രവർത്തനം

• പവർ ഓൺ/ഓഫ്: Press and hold the power button (usually located near the display) to turn the unit on or off.
• ഡിസ്പ്ലേ: The large LED display shows the current measured temperature.
• കീ ലോക്ക്/അൺലോക്ക്: To unlock the buttons for setting parameters, press and hold the "SET" button for approximately 5 seconds until the display changes or unlocks. The lock icon will disappear.

5.2 താപനില പാരാമീറ്ററുകൾ ക്രമീകരിക്കുന്നു

The STC-3000 allows you to set a target temperature and a hysteresis (difference) value to control the heating/cooling cycle.

1. ലക്ഷ്യ താപനില സജ്ജമാക്കുക:
   • Press the "SET" button once. The current set temperature will flash.
   • Use the "Up" (▲) and "Down" (▼) arrows to adjust the desired target temperature.
   • Press "OK" or wait a few seconds for the setting to be saved.
2. Accessing Advanced Settings (P-codes):
   • Press and hold the "SET" button for approximately 3-5 seconds until "P0" appears on the display.
   • Use the "Up" (▲) and "Down" (▼) arrows to navigate through the P-codes (P0, P1, P2, etc.).
   • Press "SET" again to enter a specific P-code setting.
   • Use "Up" (▲) and "Down" (▼) to adjust the value.
   • Press "OK" or "SET" to confirm and exit the P-code setting.

Common P-Codes:

5.3 Switching between Celsius and Fahrenheit

Although the product label may indicate Fahrenheit, this model primarily displays in Celsius. However, some units may have a hidden function to switch. To attempt to switch between Celsius (C) and Fahrenheit (F) display modes:

• With the unit powered on and unlocked, press and hold the gray space between the "SET" and "RST" buttons (or the "OK" button on some variants) for approximately 5 seconds.
• The display should switch between "C" and "F" indicators if this function is available on your specific unit.

6. പരിപാലനം

The STC-3000 is designed for low maintenance. Follow these guidelines to ensure longevity:

• വൃത്തിയാക്കൽ: മൃദുവായതും ഉണങ്ങിയതുമായ തുണി ഉപയോഗിച്ച് യൂണിറ്റ് തുടയ്ക്കുക. അബ്രാസീവ് ക്ലീനറുകളോ ലായകങ്ങളോ ഉപയോഗിക്കരുത്.
• സെൻസർ പരിചരണം: Ensure the temperature sensor is clean and free from debris. Do not bend or damage the sensor cable excessively.
• കണക്ഷനുകൾ: എല്ലാ വയറിംഗ് കണക്ഷനുകളും സുരക്ഷിതമാണെന്നും തുരുമ്പെടുക്കലിൽ നിന്ന് മുക്തമാണെന്നും ഉറപ്പാക്കാൻ ഇടയ്ക്കിടെ പരിശോധിക്കുക.
• പരിസ്ഥിതി: Operate the controller within its specified temperature and humidity ranges.

7. പ്രശ്‌നപരിഹാരം

If you encounter issues with your STC-3000, refer to the following common problems and solutions:

7.1 ഫാക്ടറി റീസെറ്റ്

To restore the controller to its factory default settings:

• With the unit powered on, press and hold the "RST" button for approximately 5 seconds.
• The display will briefly show "888" or similar, indicating the reset is complete.
