- Access Wiring Terminals: Carefully open the thermostat casing to access the wiring terminals. Refer to the wiring diagram provided with the product packaging for specific connections.
- Connect Wires: Connect the 230V power supply and the heat pump control wires to the appropriate terminals. Ensure all connections are secure.
- Close Casing: Securely close the thermostat casing.
4.3 Initial Power-Up
Once wiring is complete and the casing is closed, restore power to the heating system. The thermostat display should illuminate, indicating it is powered on. Follow any on-screen prompts for initial setup, such as setting the current time and date.
