Understanding Thermostat Wiring Basics
Before diving into the specifics of the Lux thermostat wiring diagram, it's crucial to understand the basics of thermostat wiring in general. Thermostats control heating and cooling systems by sending signals to the HVAC unit. The wiring typically consists of several colored wires, each serving a unique purpose.
Common Wire Colors and Their Functions
1. Red (R or Rc/Rh): This wire connects to the power supply from the furnace or air conditioner. It often serves as the primary power source for the thermostat.
2. White (W): This wire is associated with the heating system, specifically the furnace. It sends a signal to turn the heating on when the thermostat calls for heat.
3. Yellow (Y): This wire is responsible for the cooling system, signaling the air conditioner to turn on when cooling is required.
4. Green (G): This wire controls the fan. When the thermostat calls for fan operation, this wire sends the signal to activate the blower motor.
5. Blue or Black (C): This wire is the common wire, which provides a return path for the power to the thermostat. It is essential for smart thermostats that require continuous power.
