Below are the complete installation and setup instructions for the Honeywell RTH6580 thermostat.
Identify System Type
Before installing your thermostat, it’s crucial to determine your heating and cooling system type.
The RTH6580 is compatible with:
- Conventional heating/cooling systems (gas, oil, electric)
- Heat pump systems with or without auxiliary heat
However, it is not compatible with electric baseboard heating systems (120/240V).
Check your existing thermostat labels or HVAC documentation to identify your system before wiring.
Turn Off Power to the Heating/Cooling System
Before beginning any installation, turn off the power to your HVAC system at the circuit breaker or fuse box.
This prevents electrical shock and protects your thermostat and equipment from damage during installation.
Remove Old Thermostat
Remove the cover from your existing thermostat.
Take a clear photo of the wiring connections for reference.
Label each wire according to its terminal using the provided stickers in your Honeywell RTH6580 packaging.
Carefully disconnect the wires, ensuring they do not fall back into the wall.
Identify Wires
Labeling your wires correctly is one of the most important steps. Common wire labels include:
O/B – Reversing valve for heat pump systems
Make sure to match these wires exactly to the new thermostat terminals.
R / Rc / Rh – Power (24VAC)
Y / Y1 – Compressor or cooling
G – Fan control
W / W1 – Heating
C – Common wire (required for Wi-Fi models)
Mount New Wallplate
Position the Honeywell RTH6580 wallplate on the wall where your previous thermostat was installed.
Use the built-in level to ensure it’s straight.
Drill pilot holes if necessary and insert the wall anchors.
Secure the wallplate with screws.
Proper mounting ensures accurate temperature readings and stable installation.
Connect Wires
Conventional Systems (Typical Wiring)
For conventional heating/cooling systems, wiring usually follows this pattern:
- R – Power
- Y – Cooling compressor
- G – Fan
- W – Heating
If your system has both Rc and R, keep the factory jumper between them unless instructed otherwise.
Connect Wires: Conventional Systems (Alternate Wiring)
Some systems use separate Rc (cooling power) and Rh (heating power) terminals.
In that case, remove the jumper and connect the appropriate wires individually. Always follow the diagram in your Honeywell manual to ensure accuracy.
Connect Wires: Heat Pump Systems with Auxiliary/Backup Heat (Typical Wiring)
For heat pump systems, connections typically include:
- O/B – Reversing valve
- Y – Compressor
- Aux/E – Auxiliary or Emergency Heat
- G – Fan
- C – Common wire
Follow the specific wiring diagram for heat pump systems in the Honeywell RTH6580 installation guide.
Set Heating Fan Control
The fan control determines whether the fan is managed by the heating system or by the thermostat.
- For electric heat, set to “Thermostat”.
- For gas or oil furnaces, set to “Equipment”.
Set Heat Pump Reversing Valve
Heat pumps require configuration for the reversing valve.
Select O if the valve is energized during cooling, or B if energized during heating.
Incorrect settings may cause the system to heat when it should cool or vice versa.
Install Batteries and Thermostat
Insert two AA batteries into the thermostat to power the display and preserve your settings.
Then, gently snap the thermostat body onto the wallplate until it clicks into place.
System Setup (RTH6580 Honeywell Home)
Power on your HVAC system and thermostat, then follow on-screen prompts to complete setup:
- Select system type (Conventional / Heat Pump)
- Enter date and time
- Choose your preferred temperature scale (°F or °C)
- Connect to your Wi-Fi network
Once connected, download the Honeywell Home App to access remote temperature control from your smartphone or tablet.
Display Settings
Temperature Display
Choose between Fahrenheit (°F) or Celsius (°C) display modes.
Time Display Format
Select either 12-hour or 24-hour clock format based on your preference.
Heating Cycles per Hour
Adjusting the heating cycles per hour ensures efficient operation:
- Electric Heat Pump: 3–4 cycles/hour
- Fine-tuning this setting prevents excessive temperature swings and improves comfort.
Gas or Oil Furnace: 5–6 cycles/hour
Compressor Protection
This built-in feature prevents short cycling of your cooling system, helping protect the compressor and extend equipment life.
Early Start
The early start function ensures your home reaches the programmed temperature by the scheduled time.
System Startup
After all setup steps:
- Turn the system power back on.
- Confirm the thermostat display is active.
- Test heating and cooling operations.
- Check fan function and Wi-Fi connectivity.
Your Honeywell RTH6580 Smart Wi-Fi Thermostat is now ready to deliver reliable temperature control and energy savings.
FAQS
