6 Wire Thermostat Wiring Diagram

A 6 wire thermostat wiring diagram is a visual representation of how the thermostat, furnace, and air conditioner are wired together. It shows the location of each wire in the thermostat, as well as the wire colors and what they are connected to. A 6 wire thermostat is typically used in homes with heat pumps or dual-fuel systems. It has six terminals, labeled R, W, Y, G, C, and O/B. The R terminal is connected to the R wire from the furnace, the W terminal is connected to the W wire from the air conditioner, the Y terminal is connected to the Y wire from the air conditioner, the G terminal is connected to the G wire from the furnace, the C terminal is connected to the C wire from the furnace, and the O/B terminal is connected to the O/B wire from the air conditioner. If your home has a 24-volt transformer, you will also need to connect the transformer to the thermostat. The transformer is typically located near the furnace. The transformer has two terminals, labeled L and N. The L terminal is connected to the L wire from the furnace, and the N terminal is connected to the N wire from the furnace. Once you have connected all of the wires, you can turn on the power to the furnace and air conditioner. The thermostat should now be able to control the temperature in your home. Here is a more detailed explanation of the 6 wire thermostat wiring diagram: *

R terminal:

This terminal is connected to the R wire from the furnace. The R wire carries the 24-volt power supply to the thermostat. *

W terminal:

This terminal is connected to the W wire from the air conditioner. The W wire carries the signal from the thermostat to the air conditioner to turn it on or off. *

Y terminal:

This terminal is connected to the Y wire from the air conditioner. The Y wire carries the signal from the thermostat to the air conditioner to change the fan speed. *

G terminal:

This terminal is connected to the G wire from the furnace. The G wire carries the signal from the thermostat to the furnace to turn on or off the fan. *

C terminal:

This terminal is connected to the C wire from the furnace. The C wire is a common wire that is used to connect the thermostat to the furnace and air conditioner. *

O/B terminal:

This terminal is connected to the O/B wire from the air conditioner. The O/B wire carries the signal from the thermostat to the air conditioner to change the heating or cooling mode.
