4. Ntọala na nwụnye
Ọkwa nchekwa dị mkpa: 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 eserese waya
Refer to the following diagram for correct wiring connections. This model operates on DC 12V power supply.
Foto 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 Na-arịgo
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. Ntuziaka ọrụ
The STC-1000 operates in Celsius only. It cannot be switched to Fahrenheit.
5.1 Gbanyụọ ma ọ bụ gbanyụọ
- Pịa Mgbanwe ọkụ 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) na nke Difference Temperature (DT), also known as hysteresis.
- Iji view the Set Temperature (ST): Pịa nkenke Setting (S) button. The display will show the current set temperature.
- To modify the Set Temperature (ST):
- Pịa ma jide Setting (S) button for approximately 3 seconds until the display flashes.
- Jiri ihe Elu (▲) or ala (▼) buttons to adjust the desired set temperature.
- Pịa Mgbanwe ọkụ button to save the setting and exit, or wait for 10 seconds for it to save automatically.
5.3 Advanced Parameter Settings (F1-F4)
To access and modify advanced parameters:
- Pịa ma jide Setting (S) button for approximately 3 seconds until the display flashes.
- While the display is flashing, press the Setting (S) button again (do not hold) to cycle through parameters F1, F2, F3, F4.
- Jiri ihe Elu (▲) or ala (▼) buttons to adjust the value of the selected parameter.
- Pịa Mgbanwe ọkụ button to save the setting and exit, or wait for 10 seconds for it to save automatically.
| Oke | Nkọwa | Oke | Ọdabara |
|---|---|---|---|
| F1 | Difference Temperature (Hysteresis): The difference between the set temperature and the temperature at which the relay switches off. | 0.3°C ruo 10°C | 2.0°C |
| F2 | Highest Set Point Limit: Limits the maximum adjustable set temperature. | Set Temp to 110°C | 110°C |
| F3 | Lowest Set Point Limit: Limits the minimum adjustable set temperature. | -50°C to Set Temp | -50°C |
| F4 | Nhazi ọnọdụ okpomọkụ: Adjusts the temperature reading to match a known accurate thermometer. | -10°C ruo 10°C | 0.0°C |
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).
- Ụdị oyi: If the current temperature is higher than (ST + DT), the cooling relay activates. It deactivates when the temperature drops to ST.
- Ụdị ikpo oku: If the current temperature is lower than (ST - DT), the heating relay activates. It deactivates when the temperature rises to ST.
6. Nlekọta
- Nhicha: Wipe the controller's surface with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Nlekọta ihe mmetụta: Ensure the NTC sensor probe is clean and free from debris. While waterproof, avoid unnecessary physical damage to the probe or cable.
- Njikọ: Periodically check wiring connections for tightness and signs of corrosion.
- gburugburu: Operate the controller within the specified ambient temperature and humidity ranges to ensure optimal performance and lifespan.
