VAROITUS: Disconnect main power supply before performing any wiring. Incorrect wiring can cause damage to the device or heating system and poses an electrical hazard.

The receiver unit connects to your heating system. The wiring configuration depends on your specific heating application (e.g., underfloor heating, boiler, electric heating).

Kuva 5: Esim.ample wiring diagrams for various heating systems.

• Virtalähde: Connect the receiver to a 230V/50Hz mains power supply. Use the "Receiver Power Cable Input" terminals (L and N).
• Heating System Connection: Connect your heating device (e.g., boiler, actuator, electric heater) to the "Heating/Cooling Unit Connection Cable Input" terminals. This is a potential-free switching contact.

Consult a qualified electrician if you are unsure about the wiring process for your specific heating system.

5.3. Termostaatin ja vastaanottimen parittaminen

The thermostat and receiver are typically pre-paired from the factory. If they are not communicating or if you are setting up a new unit, follow these steps:

1. Ensure both the thermostat (with batteries) and the receiver (powered) are on.
2. On the receiver unit, press and hold the Pariliitospainike (often marked with a link icon) until the LED indicator starts flashing.
3. On the thermostat, access the pairing menu (refer to the specific instructions in your full manual for the exact button sequence, usually involving holding a mode or program button).
4. Once pairing is successful, the receiver's LED will stop flashing and remain solid, or turn off, indicating a successful connection.
5. Test the connection by adjusting the temperature on the thermostat and observing if the receiver activates the heating system.
