4. Поставување и инсталација
4.1 Монтирање
The STC-1000HX is designed for embedded installation. Ensure the mounting hole dimensions are 71mm x 29mm. The front panel has an IP65 waterproof rating, making it suitable for environments where splashes may occur.
4.2 Дијаграм за поврзување
Proper wiring is crucial for the safe and correct operation of the temperature controller. Refer to the wiring diagram below for connection instructions. This model requires DIY wiring; if a pre-wired product is preferred, consider the STC-1000Pro.
Figure 5: Wiring Diagram for STC-1000HX. Connect power supply (110VAC or 220VAC) to terminals 1 and 2. Connect the sensor to terminals 3 and 4. Connect the heating load to terminals 5 and 6. Connect the cooling load to terminals 7 and 8. Ensure all connections are secure and follow local electrical codes.
Важна забелешка за безбедност: Always disconnect power before performing any wiring or maintenance. Incorrect wiring can lead to damage to the device or electrical hazards.
