- Disconnect the wires from the old thermostat, noting which wire connects to each terminal.
- Remove the old mounting plate, if applicable.
Wiring the Honeywell TH5220D1029
Understanding the Wiring Terminals
The Honeywell TH5220D1029 features a terminal block with labels such as R, C, W, Y, G, and others. Here's what they typically represent:
- R: Power (24V hot wire)
- C: Common wire (returns power back to transformer, optional but recommended)
- W: Heating system control
- Y: Cooling system control
- G: Fan control
Wiring Steps
- Turn the power back ON to your HVAC system (briefly, or ensure system is energized for testing purposes).
- Identify the wires from your existing thermostat based on color and terminal labels.
- Disconnect the existing thermostat wires, then connect each wire to the corresponding terminal on the Honeywell thermostat:
- Insert the wire into the matching terminal (e.g., W wire to W terminal) and tighten the screw securely.
- Repeat for each wire: R, C, Y, G, etc.
- Ensure all wires are firmly connected and no loose strands are present.
- If your system lacks a C wire, consider installing one or use a power extender kit if supported.
