4. Persediaan dan Pemasangan
Important Safety Notice: Installation should only be performed by qualified personnel. Ensure all power is disconnected before beginning installation to prevent electric shock or damage to the unit.
4.1. Pemasangan Fizikal
- Mount the main control board in a secure, dry location, away from direct heat or moisture.
- Install the display unit in an easily accessible location for user interaction.
- Position temperature sensors (T1, T2) according to your heat pump system's requirements, typically for water temperature and ambient/coil temperature monitoring.
4.2. Gambarajah Pendawaian dan Sambungan
Refer to the main control board image below for connection points. Use the provided connectors and ensure secure connections for all wiring.

- Line-in (Power Supply): Connect the main power supply (AC ~) to the "Line-in" terminals. Ensure correct polarity (N for Neutral, L for Line).
- Pemampat: Connect the compressor unit to the designated "Compressor" terminals.
- HP (High Pressure Switch): Connect the high-pressure switch for safety monitoring.
- SM (Water Flow Switch): Connect the water flow switch to enable the water flowing warning function.
- HS (Hot Water Sensor): Connect the hot water temperature sensor (T1 or T2, depending on system design) to monitor water temperature.
- T1/T2 (Temperature Sensors): Connect the provided temperature sensors to their respective ports. These typically monitor water temperature and ambient/coil temperature for defrosting.
- Display Unit Connection: Connect the display unit to the main board using the provided cable.
Double-check all connections before applying power. Incorrect wiring can damage the unit or connected appliances.
5. Arahan Operasi
The ZL-R200A display unit features several buttons for control and monitoring:

- Butang Kuasa: Menghidupkan / mematikan unit.
- Anak panah atas/bawah: Adjust temperature settings, navigate menu options, or change parameter values.
- Butang M (Mod): Cycles through different operating modes (e.g., heating, auxiliary heating, defrost).
- S (Set) Button: Enters parameter setting mode or confirms selections.
5.1. Operasi Asas
- Hidupkan kuasa: Press the Power button to turn on the controller. The display will show the current water temperature.
- Tetapkan Suhu: Use the Up/Down arrows to adjust the desired water temperature. Press 'S' to confirm.
- Pilih Mod: Press the 'M' button to cycle through available operating modes. The display will indicate the active mode.
- Tetapan Parameter: Press and hold the 'S' button to enter the parameter setting menu. Use Up/Down arrows to navigate and adjust parameters, then 'S' to confirm and 'M' to exit. (Refer to advanced settings in a separate document for detailed parameter descriptions).
5.2. Fungsi Automatik
- Antibeku: The controller automatically activates heating elements or circulation pumps to prevent freezing when temperatures drop below a set threshold.
- Auto Nyahbeku: The system initiates a defrost cycle when ice buildup is detected on the outdoor coil, ensuring efficient operation.
- Mulakan Semula Automatik: Sekiranya berlaku kuasa outage, the controller will automatically resume its previous operating state once power is restored.
