4.1 સ્થાપન

1. પાવર બંધ કરો: Locate your circuit breaker and turn off the power to your heating and cooling system.
2. જૂના થર્મોસ્ટેટને દૂર કરો: Carefully remove your old thermostat from the wall. Take a picture of the wiring before disconnecting any wires.
3. Install 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. Attach Display: Snap the Nest Thermostat display onto the Nest Base.
6. પાવર પુન Restસ્થાપિત કરો: સર્કિટ બ્રેકર પર પાવર ફરીથી ચાલુ કરો.
