Preparing for Installation
Before starting, review the RTH6580WF PDF manual to confirm system compatibility and locate existing wiring. Turn off power to the HVAC system safely.
Identifying System Compatibility
Ensuring compatibility is crucial before installing the Honeywell RTH6580WF. The PDF manual details supported heating and cooling systems, including conventional, heat pump, and radiant systems.
Carefully check your existing system’s voltage – the RTH6580WF typically requires 24 VAC. Note if your system labels the 24 VAC common (C-wire) terminal; if not, consult your system’s documentation or manufacturer.
The manual clarifies if your setup needs a C-wire adapter, and provides guidance. Incorrect wiring can damage the thermostat or HVAC system, so thorough verification is essential for a successful installation.
Locating the Existing Thermostat Wiring
Before disconnecting your old thermostat, carefully document the existing wiring. The PDF manual emphasizes taking a clear photograph of the wiring connections as a reference.
Identify each wire’s terminal designation (e.g., R, W, Y, G, C). Note that wire colors can vary, so rely on the terminal labels, not the wire color alone.
The manual advises caution when removing wires, and suggests labeling them with small pieces of tape corresponding to their terminal designations. This meticulous approach prevents confusion during the RTH6580WF installation process, ensuring correct reconnection.
Turning Off Power to the HVAC System
The RTH6580WF installation manual PDF strongly emphasizes safety, beginning with disconnecting power to your HVAC system. Locate the circuit breaker that controls your furnace and air conditioner.
Turn the breaker to the “OFF” position. To verify power is completely off, the manual recommends using a non-contact voltage tester at the thermostat wires.
Never proceed with wiring until you’ve confirmed no voltage is present. This crucial step prevents electrical shock and potential damage to the thermostat or HVAC system. Re-check before touching any wires!

Wiring the RTH6580WF Thermostat
The RTH6580WF installation manual PDF details precise wiring instructions. Identify wires, including the common (C-wire), and follow the diagrams carefully for correct connections.
Identifying Common Wires (C-Wire)
The Honeywell RTH6580WF thermostat often requires a common (C-wire) for consistent power. However, not all systems readily label this wire. The PDF installation manual emphasizes checking your existing HVAC system’s wiring diagram or contacting the manufacturer to definitively identify the 24 VAC common terminal.
Older systems might not have a C-wire initially installed. In such cases, the manual provides guidance on potential solutions, including utilizing a C-wire adapter kit. Correctly identifying the C-wire is crucial for reliable thermostat operation and Wi-Fi connectivity. Miswiring can lead to functionality issues, so careful verification is essential before proceeding with the installation process. Refer to the PDF for detailed diagrams and troubleshooting tips.
Connecting the Wires – Detailed Instructions
