• Installazione professionale: If you are unsure about any part of the installation process, consult a qualified HVAC professional.
• Solo per uso interno: This device is designed for indoor use in residential or light commercial environments.
• Gestione della batteria: The thermostat uses AA batteries. Ensure correct polarity when inserting batteries. Do not mix old and new batteries or different types of batteries.

4. Impostazione

4.1 Installazione

1. Spegni l'alimentazione: Individua l'interruttore automatico e spegni l'alimentazione del sistema di riscaldamento e raffreddamento.
2. Rimuovere il vecchio termostato: Carefully remove your old thermostat from the wall. Take a picture of the wiring before disconnecting any wires.
3. Installa Nest Base: Mount the Nest Base to the wall using the provided screws and anchors. Ensure the base is level.
4. Wire the Nest Thermostat: Connect your system's wires to the corresponding terminals on the Nest Base. The Nest Thermostat is compatible with most 24V heating and cooling systems. A C-wire (common wire) is often recommended for consistent power, especially with systems that do not provide continuous power to the thermostat. If you do not have a C-wire, the Nest Thermostat may still work by 'power stealing' from other wires, but this can lead to intermittent issues.
5. Allega display: Snap the Nest Thermostat display onto the Nest Base.
6. Ripristina alimentazione: Riattivare la corrente tramite l'interruttore automatico.
