4. ማዋቀር እና መጫን

ጠቃሚ የደህንነት ማስታወቂያ፡- Installation should be performed by qualified personnel. Ensure power is disconnected before wiring to prevent electric shock. Strictly distinguish between power supply, sensor, and relay interfaces. Maintain proper distance between sensor down-lead and power wires to avoid interference.

4.1 የሽቦ ዲያግራም

Refer to the following diagram for correct wiring connections. This model operates on DC 12V power supply.

ምስል 3፡ Wiring diagram for the STC-1000 12V temperature controller. Connections are for power supply, NTC sensor, heating relay, and cooling relay.

• Terminals 1 & 2: Power Supply (DC 12V).
• Terminals 3 & 4: NTC Sensor connection.
• Terminals 5 & 6: Heating Relay Output (Connect to heating device).
• Terminals 7 & 8: Cooling Relay Output (Connect to cooling device).

Ensure all connections are secure and insulated. Verify the power supply voltage matches the controller's requirement (DC 12V for this model).

4.2 መጫን

The STC-1000 is designed for panel mounting. Cut an opening of 71mm x 29mm in your panel. Insert the controller and secure it using the provided clips or mounting brackets.

5. የአሠራር መመሪያዎች

The STC-1000 operates in Celsius only. It cannot be switched to Fahrenheit.

5.1 ማብራት / ማጥፋት

• የሚለውን ይጫኑ የኃይል መቀየሪያ button (marked with ⏻) to turn the controller on or off.

5.2 Setting Temperature Parameters

The controller has two main temperature settings: the Set Temperature (ST) እና የ Difference Temperature (DT), also known as hysteresis.

1. ለ view the Set Temperature (ST): በአጭሩ ይጫኑ Setting (S) button. The display will show the current set temperature.
2. To modify the Set Temperature (ST):
   • ተጭነው ይያዙት። Setting (S) button for approximately 3 seconds until the display flashes.
   • የሚለውን ተጠቀም ወደላይ (▲) or ታች (▼) buttons to adjust the desired set temperature.
   • የሚለውን ይጫኑ የኃይል መቀየሪያ button to save the setting and exit, or wait for 10 seconds for it to save automatically.

5.3 Advanced Parameter Settings (F1-F4)

የላቁ መለኪያዎችን ለመድረስ እና ለማሻሻል፦

1. ተጭነው ይያዙት። Setting (S) button for approximately 3 seconds until the display flashes.
2. ማሳያው ብልጭ ድርግም እያለ፣ ይጫኑ Setting (S) button again (do not hold) to cycle through parameters F1, F2, F3, F4.
3. የሚለውን ተጠቀም ወደላይ (▲) or ታች (▼) buttons to adjust the value of the selected parameter.
4. የሚለውን ይጫኑ የኃይል መቀየሪያ button to save the setting and exit, or wait for 10 seconds for it to save automatically.

5.4 Heating and Cooling Modes

The STC-1000 automatically switches between heating and cooling based on the set temperature (ST) and difference temperature (DT).

• የማቀዝቀዝ ሁኔታ; If the current temperature is higher than (ST + DT), the cooling relay activates. It deactivates when the temperature drops to ST.
• የማሞቂያ ሁነታ; If the current temperature is lower than (ST - DT), the heating relay activates. It deactivates when the temperature rises to ST.
