Installation Guide
Proper installation requires careful wiring and mounting. Consult the detailed wiring diagrams and follow step-by-step instructions for a successful setup!
Wiring Diagram Overview
Understanding the wiring is crucial for a correct installation of your Honeywell RTH9585WF thermostat. The diagram illustrates the connections for various system types, including conventional heating and cooling, heat pumps, and systems with a common (C) wire. Carefully identify your existing wiring before disconnecting anything from your old thermostat.
Key terminals include Rh and Rc for heating and cooling power, W for heating, Y for cooling, and G for the fan. A C-wire provides continuous power to the thermostat. Refer to the diagram to match your wires to the corresponding terminals on the thermostat base. Incorrect wiring can damage your system, so double-check all connections before proceeding. Always power off your HVAC system at the breaker before working with the wiring.
C-Wire Requirement and Alternatives
The Honeywell RTH9585WF thermostat generally requires a common (C) wire for consistent power. Without a C-wire, the thermostat may draw power from other wires, potentially causing system instability. If you lack a C-wire, several alternatives exist. A C-wire adapter can repurpose an unused wire, or you might be able to utilize the G (fan) wire with a compatible adapter.
However, using adapters can sometimes introduce compatibility issues. Carefully review the adapter’s instructions and ensure it’s compatible with your HVAC system. Alternatively, running a new C-wire from your furnace or HVAC unit is the most reliable solution, though it may require professional assistance.
Mounting the Thermostat Base
Before mounting, ensure the HVAC system is powered off at the breaker. Remove your old thermostat, carefully labeling the wires. Use the included mounting screws to attach the thermostat baseplate to the wall. Ensure the base is level for proper display alignment.
Feed the thermostat wires through the opening in the baseplate. Confirm the wires are not pinched or strained. The baseplate should sit flush against the wall; use shims if necessary to compensate for uneven surfaces. Double-check that the base is securely fastened before proceeding to wire connections.
Connecting the Wires – Step-by-Step
Refer to your labeled wires and the wiring diagram. Carefully insert each wire into the corresponding terminal on the thermostat base. Ensure each wire is securely fastened within the terminal – a gentle tug confirms a solid connection. Avoid stripping the wire insulation beyond the recommended length.
If a C-wire is present, connect it to the ‘C’ terminal. For systems without a C-wire, explore the alternative power options detailed in the manual. Double-check all connections against the wiring diagram before proceeding. Incorrect wiring can damage your HVAC system.
