5. Instal·lació
The STC-1000 controller is designed for panel mounting. Proper wiring is crucial for safe and correct operation.

Figura 5.3: Angle view of the STC-1000 controller wiring.
Instruccions de cablejat:
- Font d'alimentació (terminals 1 i 2): Connect the AC 110V-220V power supply to terminals 1 and 2. Ensure correct polarity if applicable, though for AC, line and neutral can typically be interchanged.
- NTC Sensor (Terminals 3 & 4): Connect the NTC temperature sensor probe to terminals 3 and 4. The sensor is non-polarized.
- Heating Output (Terminals 5 & 6): Connect your heating device to terminals 5 and 6. This is a relay output, so ensure the heating device's power requirements do not exceed 10A/220VAC.
- Cooling Output (Terminals 7 & 8): Connect your cooling device to terminals 7 and 8. This is also a relay output, with a maximum capacity of 10A/220VAC.
Nota important: Strictly distinguish the interface of the relay, sensor, and power. Ensure the sensor down-lead and power wire are kept a proper distance to avoid interference.
6. Funcionament
The STC-1000 controller operates in two main modes: display mode and setting mode.
Mode de visualització
When powered on, the controller displays the current temperature measured by the NTC sensor.
Configuració de paràmetres
To enter the parameter setting mode, press and hold the 'S' button for 3 seconds. The display will show 'F1'. Use the UP (▲) and DOWN (▼) buttons to navigate through the parameters (F1, F2, F3, F4). Press 'S' again to view or modify the value of the selected parameter. Use UP (▲) and DOWN (▼) to change the value, then press 'S' to confirm and save. To exit setting mode, press the power button or wait 10 seconds for it to automatically exit.
Parameter Functions:
- F1: Temperature Setting Value (Set Point)
This is the desired temperature you want to maintain. Range: -50℃ to 99℃. - F2: Differential Value (Hysteresis)
This sets the temperature difference between the set point and when the heating/cooling output activates. For example, if F1=25℃ and F2=2℃:- In cooling mode, cooling starts at 27℃ (25+2) and stops at 25℃.
- In heating mode, heating starts at 23℃ (25-2) and stops at 25℃.
- F3: Compressor Delay Time (Delay Start)
This parameter sets a delay before the compressor (cooling or heating device) starts after power-on or a cycle change. This protects the compressor from frequent starts. Range: 0 to 10 minutes. - F4: Calibració de la temperatura
Allows you to adjust the displayed temperature to match a known accurate thermometer. If the controller reads 25℃ but a reference thermometer reads 26℃, set F4 to +1.0℃. Range: -10℃ to 10℃.
Heating and Cooling Mode Selection
The controller automatically switches between heating and cooling based on the set point (F1) and differential (F2).
- If the current temperature is més alt than (F1 + F2), the cooling relay activates.
- If the current temperature is inferior than (F1 - F2), the heating relay activates.
7. Manteniment
- Regularly clean the controller's display and buttons with a soft, dry cloth.
- Ensure the sensor probe is clean and free from debris that could affect temperature readings.
- Reviseu periòdicament totes les connexions del cablejat per assegurar-vos que estiguin ben fixades.
- Avoid exposing the main unit to water or extreme temperatures.
8. Solució De Problemes
| Problema | Causa possible | Solució |
|---|---|---|
| Display shows 'HHH' or 'LLL' | Sensor error (open circuit or short circuit) or temperature exceeds range. | Check sensor wiring. Replace sensor if damaged. Ensure temperature is within -50℃ to 99℃. |
| Display shows 'EEE' | Sensor error or internal fault. | Check sensor wiring. If problem persists, the unit may be faulty. |
| Controller not responding to temperature changes | Incorrect F1/F2 settings, sensor not properly placed, or delay time (F3) is too long. | Verify F1 and F2 settings. Ensure sensor is accurately measuring the desired area. Check F3 setting. |
| El dispositiu de calefacció/refrigeració no s'encén/apaga | Incorrect wiring, device faulty, or relay failure. | Recheck wiring connections for heating/cooling outputs. Test the connected device independently. |
