Understanding the Trane Voyager Wiring Diagram
The wiring diagram for the Trane Voyager series is a schematic representation showing all electrical connections between components such as the thermostat, contactors, relays, capacitors, and the outdoor and indoor units. It illustrates how power flows through the system and how control signals activate various components.
Key Elements of a Trane Voyager Wiring Diagram:
- Power Supply Lines: Usually labeled as L1 (hot) and L2 (neutral or common), these provide the electrical power to the system.
- Thermostat Connections: Typically marked R (power), C (common), Y (cooling), W (heating), G (fan), and auxiliary signals.
- Contactor and Relay Controls: Switches that activate the compressor and fan motors.
- Capacitors: Assist in starting and running motors efficiently.
- Control Boards: Manage the overall operation, including safety features and diagnostic indicators.
- Sensors and Safety Switches: Such as pressure switches, limit switches, and temperature sensors.
A well-designed wiring diagram not only shows the connections but also indicates the wire colors, terminal labels, and voltage ratings, which are crucial for correct wiring.

Components of a Trane Voyager System and Their Wiring
Understanding the individual components and their wiring is fundamental to interpreting the diagram.
1. Thermostat
- Sends control signals to the system.
- Connects via wires labeled R, C, Y, W, G, and sometimes O or B for heat pump reversing valves.
- Controls the activation of compressor, fan, and auxiliary heating.
2. Contactor
- An electromagnetic switch that controls power to the compressor and fan motor.
- Wired to the thermostat control signals and supply voltage.
3. Capacitors
- Start capacitor and run capacitor are wired to motors to assist in starting and running.
- Proper wiring ensures motors operate smoothly.
4. Indoor and Outdoor Units
- Indoor unit includes the blower motor, indoor coil, and control board.
- Outdoor unit contains the compressor, outdoor coil, contactor, and fan motor.
- Wiring connects these units to the control board and power supply.
5. Control Board
- The central control hub that manages signals from the thermostat and sensors.
- Provides diagnostic LEDs and test points.

How to Read a Trane Voyager Wiring Diagram
Interpreting the wiring diagram involves understanding symbols, labels, and color codes.
Step-by-Step Guide:
- Identify Power Sources: Locate the power supply lines L1 and L2, ensuring proper voltage (typically 208/230V).
- Follow Control Wiring: Trace wires from the thermostat to the control board, noting the terminal labels.
- Check Component Connections: Confirm that the contactor coil is wired correctly to activate with the thermostat signal.
- Inspect Capacitor Wiring: Ensure capacitors are wired in parallel with the motors according to the diagram.
- Verify Safety Switches and Sensors: Make sure limit switches, pressure switches, and other safety devices are correctly integrated.
- Look for Color Codes: Wire colors are typically standardized; for example, yellow for cooling, white for heating, and green for fan control, but always verify with the specific diagram.
Common Symbols and Notations:
- Switches: Represented by a breakable line or a switch symbol.
- Motors: Indicated by a circle with an 'M'.
- Capacitors: Shown as two parallel lines with polarity marked.
- Transformers: Rectangular symbol with primary and secondary windings.
