FAQ
What is the difference between an 8 wire and a 5 wire Honeywell thermostat?
The main difference between an 8 wire and a 5 wire Honeywell thermostat is the number of wires that are used to control the heating and cooling system. While a 5 wire thermostat is designed to work with heating and cooling systems that use 5 wires, an 8 wire thermostat is designed to work with systems that use 8 wires.
Can I install an 8 wire Honeywell thermostat myself?
Yes, you can install an 8 wire Honeywell thermostat yourself if you are comfortable with basic electrical wiring. However, if you are not confident in your ability to safely wire your thermostat, it is best to hire a professional HVAC technician to do the job for you.

If you have extra wires that are not used in your heating and cooling system, you can simply leave them unconnected. However, if you are unsure about which wires to connect, it is best to consult the manufacturer’s instructions or hire a professional HVAC technician to do the job for you.
What is the purpose of the heat pump reversing valve?
The heat pump reversing valve is a component that is used in heat pump systems to switch the flow of refrigerant between the indoor and outdoor units. This valve is necessary for the heat pump to switch between heating and cooling modes.
What do I do if my thermostat is not working?
If your thermostat is not working, check to make sure that all the wires are connected properly and that the power to your heating and cooling system is turned on. If the problem persists, it may be a problem with the thermostat itself, and you may need to replace it.
Overall, wiring your 8 wire Honeywell thermostat is not difficult if you follow the instructions carefully.
