How do you wire a Honeywell thermostat correctly?

To wire a Honeywell thermostat correctly, first turn off the power to your heating and cooling system. Then, remove the old thermostat and label the wires according to their corresponding terminals. Next, connect the labeled wires to the matching terminals on the new Honeywell thermostat. Finally, secure the thermostat to the wall and turn the power back on to test the system.
